Medical Coding for Beginners

are you someone who's interested in medical coding maybe you're thinking about this as a future career path or you already work somewhere in healthcare and you just want to know a little bit about medical coding enough to get through the day well you're in luck because today i'm going to be talking about the beginner's guide to medical coding [Music] hey everyone i'm victoria i'm a medical coder auditor educator and content creator and on my channel i provide tips tricks and tutorials to help you be successful in a medical coding career today we're going to go over medical coding 101 the beginner's guide and make sure you stick around till the end because we're going to do some hands-on coding cases so let me start out just saying with medical coding it is not something that you need to have even an associate's degree or a bachelor's degree in order to become a certified coder most employers are just looking that you have a certification through ahima or aapc i myself am a very proud community college girl i went through their career programs and i have a certificate as a medical billing specialist and then i became certified as a professional coder from the aapc there are just so many amazing amazing opportunities in medical coding and if you take advantage of all these opportunities you are going to have an enormous amount of different growth potential to get into things like compliance and auditing and specialties there's even certain specialties in medical coding like interventional radiology that pay a lot of money medical coding is reviewing medical records analyzing them abstracting certain pieces and then converting them into medical codes now sometimes all the pieces aren't there you might need to go back and have them correct the documentation so that you can abstract the best code possible but that is a very simplified process so medical coding involves every diagnosis and procedure known to man and as part of a healthcare team you do need to understand things like medical terminology and anatomy and physiology so that you can be the best coder you can be now medical coding is not just for reimbursement but that's the first thing that comes to mind because we hear this term medical billing and coding and we think oh these are kind of tied sometimes people do both sometimes there's a biller sometimes there's a coder and they do one does billing one does coding so medical coding does not just serve purposes for billing and reimbursement there is also a lot of data in it because we need to track how many patients have certain diseases and how often those diseases progress into something else how many times those patients have complications and there are different codes to identify that there's a code for a patient that has diabetes and there's all kinds of different codes for diabetic complications and that way we can look at those data analytics and determine how many patients that have uncomplicated diabetes are likely to develop some kind of complications what complications are they developing and then we can look at other things like well what services did the patients who didn't develop complications receive are these services that we should start giving to patients so that we can cut down on health care costs so there's a lot more involved in medical coding than just getting reimbursed from insurance companies and there's different code sets that we use and depending on what type of coding you do you might use all of them or you might use only one of them there is professional coding that's the most popular one that medical coders get into where you use icd-10 cpt and hick picks but we also have things like the icd-10-pcs let me show you some of the books i have for medical coding so this is my icd-10 cm manual this is the international classification of diseases version 10 and this is the cm clinical modification there's different versions of icd-10 that are used throughout the world but the cm version is the one that's used in the united states so other countries have a different abbreviation here for the version that they're using in their country so icd-10-cm is diagnosis codes and then other little codes that give information about things like if you're at risk for developing cancer you have a family history of cancer you're coming in for an encounter for your routine physical exam so maybe there's not necessarily a diagnosis there but we have a diagnosis code to identify oh yeah this is a patient who's presenting for their routine physical exam then we have our cpt code cpt is current procedural terminology so cpt this is my 2021 edition so depending on what type of coding you do you might not use cpt if you do inpatient coding you might not do a lot if you do risk adjustment you're not going to use any cpt but cpt is current procedural terminology and this is published by the ama and these are all the different medical services and procedures so this hcpcs book we call hick pics it is the healthcare common procedural code set it has durable medical equipment drugs and then there's some insurance specific information and services as well and then icd-10-pcs i actually don't code for icd-10-pcs because this is used in inpatient coding and i don't do in-patient coding i do do profi outpatient and risk adjustment coding so this is icd-10 pcs and this is the ic10 procedural code set and that is for inpatient coding you know what i almost forgot there's another code set c d t which is the dental code so i've never coded for dental i don't know a lot about dental coding but that is an additional code set specifically for dental coders if you're interested in learning about the best medical coding books to get not just ones to learn the code sets but also to learn how to code and learn medterm too i have a great video on my best recommendations for medical coding books you can find it here in the tag and then i will also link it in the description below now if you're interested in learning about the typical day in the life of a medical coder i have a whole video on that you can check that out here and in the description but let's talk about salary so according to the aapc salary survey the average salary for a certified professional coder is usually around 57 000 now that's average that includes the people who have 20 30 years experience starting salaries are more like 38 000 or so for starting wages for professional coders now this varies a lot depending on your state your country and there's a lot of information that goes into it aapc actually has a salary calculator that they use they have information about different regions i have a video specifically on salaries for medical coders again check out that link and i'll put it in the description below medical coders can work in a lot of variety of places they could work in provider offices they can work in hospitals they can work for insurance companies they can work for vendors they could work for lawyers in the legal sector there are coders that work just for companies that hire coders that they're kind of outsourced companies they just do billing and coding they could work anywhere in the revenue cycle and there's a lot of opportunity for growth and medical coding you can specialize in certain types of coding like you could do just cardiology or urology oftentimes the more and more specialized your niche is you can make more money but having that broad range of knowledge is exceptional as well so medical coding is not as simplified as some people think they feel like oh it's just kind of looking up things like you would in a phone book and you assign the right number like if i look up john smith in the phone book i'm going to find john smith's phone number it's not quite that simple there's a lot of analyzing that goes into medical coding a lot of interpretation a lot of reading goes into medical coding and understanding that you're part of the healthcare team you do have to know some clinical information and understand the impact that incorrect coding can have on finances so i'm going to talk a little bit about professional coding professional coding is coding for provider-based services so your doctor doing your physical exam your surgeon doing your cholecystectomy all the different services and procedures that are provided by providers versus inpatient coding where they are coding for services that you were formally admitted to the hospital and coding for that whole inpatient hospital stay there's also risk adjustment coding that just works with diagnoses then there's outpatient coding which is services that were provided in an outpatient facility like an ambulatory surgical center let's actually start with the icd-10-cm book so there's a couple sections to the icd-10-cm book at the very front you will find your alphabetic index which is the a-to-z listing of terms that you're going to look for for diagnoses and other types of encounter status types now one of the first things you have to do is locate your key term and that key term can be easy if it's just a one word diagnosis but if you've got a diagnosis that's six or seven words you have to figure out what that key word is and i'll talk about this as we go through our demonstration so what you do is you find your keyword and you look in the alphabetic index in the front so i'm looking right now at the page that says infection and there's tons of different infections so if i'm looking for an infection i have to narrow that down so is there an infection so here we have infection of the pinworm it says infection pinworm is b80 so once i found that code i can't just assign b80 i have to verify that in what's known as the tabular list so the tabular list is back here now this alphabetic index isn't just the only alphabetic index we have we also have a couple of tables so there's the general alphabetic index then we have a table for drugs and chemicals so those are things like poisoning and self-harm with different types of substances and that could be a substance like alcohol it could be different types of medications and then we have our table of neoplasms so that's commonly used for things like cancer or carcinoma in situs or even benign lesions so this is the same table we would use for things like moles and other lumps and bumps that a patient may have in different areas and then we have the index for external causes of injury and those are the ones that people find more humorous codes in because the diagnosis codes that we have are not just things like cellulitis and inflammation and pain and headaches it's also things like being bitten by a cow being sucked into a jet engine or even injured while knitting so icd-10-cm you can get for free there are free versions that you can get through the cdc or through cms they are not formatted like an ebook they're in all kinds of different pdf files there are some tricks i'll probably show in a future video where you can take those and kind of format them into one full pdf ebook but this you can get for free and again you look things up in the alphabetic index verified in the tabular i'll take you through a couple of cases so with icd-10-cm you look up in the alphabetic index verify in the tabular list and sometimes it'll give you additional instructions it'll say hey this condition that you're looking for isn't included here or it'll say hey we need you to code something else first before you code this or you need to code something else after this or hey this code might not be the best maybe look for this or hey or they might say you need to verify that this is the right wrist or the left wrist or was it bilateral and there's a lot of guidelines that have to be followed in icd-10-cm there's pages of them and pages of them usually at the front of your book some additions have them in the back you can download them for free as well and i actually have a whole playlist just about the icd-10-cm guidelines i go through the whole shebang so it's sequencing things it's about when a patient presents for this condition and they also have this condition this is what goes first this is when you can code for this you can't code for this and a lot of really nitty gritty details and then there's even additional stuff kind of going on behind the scenes but i'm not going to talk about that for this video hey if you're enjoying this content you definitely want to make sure that you subscribe and hit that notification bell so you can get alerts when i post new episodes cpt the index is in the back so there is an official guidance with cpt of how you have to look it up so there is with icd-10-cm you have to go to the alphabetic index verify in the tabular list look at all the additional instructions with cpt there isn't an official way that you have to look up so there are different chapters broken out by body systems so for example we have one that is cardiovascular we have digestive and then we have other sections like medicine services or evaluation and management which are things like your providers just kind of doing an exam getting your history making some decision making processes you might think about it as something like your pcp visit you're going in to see your primary care physician because you have chronic conditions he's managing or he or she is seeing you for an upper respiratory infection so they're determining you know what your course of treatment is going to be and those are those office visits are based off of different levels and there's all kinds of code integrations that go into how we figure out what that level of service is going to be so with cpt you can look it up in this alphabetic index and then go to that particular chapter to verify it or what some coders do is they go to these specific chapters so each chapter has a table of contents in it so for example this is the surgical digestive system and they go into lips and all the other different areas so if you're looking for something that's maybe an incision or excision of the stomach you would go down here try to find the section that says stomach and then you would go into okay what's the thing we did to the stomach did we do a biopsy did we do an incision did we do an excision what did we do and just kind of locate the code through searching that way so the cpt book is all the procedures and services that could be done to a patient and then we have what's called bundling so for example if we're doing a hernia repair on the patient and we open them up to repair the hernia obviously we're going to close them so even though there's different codes foreclosures that's included in that code for the hernia repair because if we open them up to repair a hernia we're going to close them back up so we don't code that additional code for closure we just code the code for the hernia repair because it encompasses everything typically involved in repairing a hernia now cpt is maintained by the ama so they own all of the rights and they do not provide any of the materials in the cpt index for free there's one resource you can use to kind of look up some descriptions and you can only do a limited amount of them but generally speaking you need to purchase the cpt book there is also an ebook version i actually prefer my paper version even though i'm a very techy person i have the ebook of the cpt but i like my paper book now each chapter has specific chapter guidelines and then there's even some guidelines in addition to that so if you look at the section for removing a lesion like a mole on your arm or your trunk it goes based off of things like location so you need to know in the documentation where was it located what size was it and there's even guidelines on specifically how we determine what size we use for code selection because there might be different sizes documented and we might even have to do a little bit of math if you're concerned about the math i have a video on that too about how much math is involved in medical coding so this page for example gives us all the guidance that we need for how to select the appropriate size for excision of a lesion and how we measure and how we figure out what the measurement is that we use for code selection so now let's dive into a couple of cases so i can show you hands-on what it looks like when you are coding some medical records so this first case that i want to look at with you guys is a carpal tunnel repair so this is a surgical procedure that we're going to code so this one we have a pre-operative diagnosis and a post-operative diagnosis you'll see these in most procedure and surgery codes so in this case we have right carpal tunnel syndrome is our pre and postop you may see this change sometimes if the patient had something discovered during surgery they went in they opened them up it wasn't what they thought it was going in so that might be different so we always code based off of that post-operative diagnosis because that's usually the more specific of what we're looking at the other thing to consider is pathology so we might open this patient up to remove a tumor and then we send that tumor to tumor to pathology and discover if it was cancerous it's non-cancerous what type of tumor is it so if we have something where we sent a specimen we wait until we get that report back of what was that specimen because that's going to be the most specific diagnosis and that's what we're going to use for what we're coding so if we look here this patient had right carpal tunnel syndrome right's going to be important and then the whole diagnosis and then the procedure was performed on the right side and that's going to impact some things we do with our coding as well so this was a right carpal tunnel release and even though we have this procedure listing here we never code directly based off of just this procedure performed we have to read this whole operative report to verify that this is exactly what the provider is describing down here sometimes there's extra things sometimes they omit things sometimes they don't put a size in incorrectly that women have to go back to this provider and go hey we can't code this the way that it needs to be for this procedure that was performed because you omitted this little piece of information can you add that back in or maybe there was just something that wasn't a hundred percent clear so it's always important to read this now this is i would say a medium to small size operative report there are ones that are quite long uh sometimes three four pages depending on what was done with that patient and you might have to read it a couple of times in order to abstract all of the codes to the highest accuracy and then verify if some of them are already included in other codes so it isn't just as easy as looking it up in the book and signing the code and then you move on to the next case there's a lot of reading and analytics involved into it so in this case the procedure note says the right upper extremity was prepped and draped in the usual fashion iv sedation was supplied by the anesthesiologist a local block using 6 cc of 0.5 markain was used at the transverse wrist crease using a 25 gauge needle superficial to the transverse carpal ligament so this is the anesthesia portion of it and we're not coding for the anesthesia because we're coding for the surgery we're coding for the surgery itself so this is the upper extremity was exaggerated with a six inch ace wrap and then this is their tourniquet time less than 10 minutes so here is what we need to really read dive into and then abstract the important pieces this is the body of the operative report and this is the step-by-step provider's description of what they did so an incision was used in line with the third web space just to the ulnar side of the fennar crease it was carried sharply down to the transverse wrist crease on the right wrist and this is the important part the transverse carpal ligament because that's what we're working on right was identified and it was released under direct vision proximal to the transverse risk crease it was released subcutaneously good so during the entire procedure care was taken to avoid injury to the median nerve proper the recurrent median the palmar cutaneous branch the ulnar neurovascular bundle and the superficial palmar arch the nerve appeared to be mildly constricted that's why they are doing that release closure was routine running 5-0 nylon a bulky hand dressing as well as a volar sprint splint was applied and the patient was sent to the outpatient surgery area in good condition so the important thing about this is they're basically saying we didn't accidentally nick any of these nerves and if they did that's actually not something we can build to the patient patient they're sort of a you break it you buy it policy with surgeries if they go in and they accidentally break something else that's not something that gets built to the insurance or sent for patient responsibility it's something that the hospital just kind of has to eat although sometimes depending on how it's organized you might have to code it out and then they just write that code off because they want to maybe keep track of it so then we just have the closure here now anytime a patient is opened up it stands to reason they're also going to be closed so in the majority of cases closure coding is included so you don't code additionally for suturing the patient closed so let's look at this we have a diagnosis that we're going to need to abstract diagnosis and then our our cpt code right so our diagnosis here is the same we didn't find anything else in here that looked like maybe this was not correct or we needed to maybe look at a different code or get clarification it was a right carpal tunnel syndrome so with icd-10-cm we always look for the key word what's our keyword that we're going to look for in the alphabetic index what are we going to start with and it's suggested to not start with a body area or system or part because the reason is if i want to start and look at the word wrist it would tell me c condition and what that means is don't look at the word condition it means what is the condition of the wrist is it lacerated is it fractured is it sprained what is that condition and that's the word you should look at laceration fracture sprain and go from there so in this case we're not going to look at right we're not going to look at carpal we're not going to look at tunnel we're going to look at syndrome that's going to be our keyword now if you don't pick the right keyword right away it's not the end of the world you can just go back and go oh maybe i'm supposed to look up this different word instead or maybe there's an alternative word that means the same thing that you can look up so maybe it's described as a disorder but it's actually under disease in the alphabetic index so let's start with the word syndrome we have a lot of different syndromes as you can imagine so we start in the alphabet index and the beginning of the word syndrome i believe might be on this page at the very bottom corner i have it so syndrome and it says see also disease so what are we looking for syndrome and this is our main term and then we have indentations here for each additional further clarification that we have so we're going to need to flip to our next page to find the word i'm assuming carpal so syndrome carpal tunnel let's see what we can find syndrome here's our b indentations here's our c so oh here we go right here is carpal tunnel g56.0 now there's a little check mark here in mind now that isn't always in every single book but let me zoom in here that isn't in every single book but it's helpful in this book because what it's basically saying is hey double check this because you might need an additional character which stands to reason because they don't have here right or left and we're probably going to want to know right or left right was it was it carpal tunnel syndrome on the right side or the left side so we never ever code directly from the alphabetic index we always verify it in the tabular list so we're going to go now into our tabular list and look at this g56.0 and know since we have this check mark here we're probably going to need some additional characters or there's going to be some additional guidance there for us so here is our g5 6.0 and you can see it says that we need and this is real tiny it might not pick up on the camera we need a fifth character so these are all of the additional extensions that we have we have carpal tunnel syndrome unspecified right left and bilateral so let's double check our report what does it say it says that this was the right carpal tunnel g56.01 carpal tunnel syndrome right upper limb and next we need to find our procedure code so our procedure is a right carpal tunnel release and there's a couple of different ways that people can tackle finding a procedure code in cpt so with icd-10cm they have official guidelines on how this is how you look up the code you go in the alphabetic index you find the main term you verify it in the tabular list there's actually not an official way you need to look up cpt codes some people prefer to use their alphabetic listing in the back other people prefer to go to that specific system and then decide from there in their table of contents like what was it what we were doing was the digestive system okay well it was the stomach we did an incision into the stomach and find the code that way for this demonstration i'm actually going to show you both so the term that they're using here is right carpal tunnel release so i'm going to check the word release if i can't find a release i might look at something maybe like repair and then see if i can find it that way so release so here's release and we have capsule and oh carpal tunnel is right there six four seven two one i'm gonna write that down right now six four seven two one so i don't forget it so here it is six four seven two one now this isn't the full description here so what we do in cpt to kind of i guess save space is we have terms and i'll zoom you guys in here we have terms kind of abbreviated so this is the main part of this description neuroplasty and or transposition and then you see that semicolon and when you see a semicolon in cpt that means stop and that stop means that here's where we can go for this code here's where we go for this code here's where we go for this code so neuroplasty and our transposition now six four seven one six this is the full description neuroplasty and our transposition cranial nerve and then specify but that's not what we did we did this median nervous carpal tunnel this full description is everything after that semicolon so neuroplasty and or transposition stop go here median nerve at carpal tunnel so 64721 that's our code six four seven two one that's right we're verifying does it say that we should there's some additional guidance here do not report six four seven one six six one eight six four seven two one in conjunction with one one nine six zero okay so that's fine nothing else that we need to be too worried about here it doesn't say to add on an additional code for any other section that was done here so 64721 looks like it's it now the way we could also find this in the table of contents and i'll show you that right now so let's go to the cable contents so here is our nerves nervous system so here we have a listing of the nerves of the skull no spine noob that's not where we are we're in the median nerve of the wrist okay so extra cranial peripheral nerves and autonomic nervous system and here is where we have neuroplasty and that's what we did we decompressed those carpal tunnel nerves so that's how you would find it in the table of contents this one's not as obvious as some of the others are but that's where it is we did this decompression of the carpal tunnel nerves now we're not quite done yet because we also have in cpt what are called modifiers and they're two digit codes that modify the procedure code the modifier that we're going to need in this case is going to clarify that this procedure was done on the right side so just because we have a right sided diagnosis doesn't mean it was a right side procedure as well a good amount of the modifiers are in the inner flap of your cpt book they're also in appendix a for the full descriptions and then there's some that are actually in the hicpix book so for this one these are our rt so rt means it's the right side of the body so we're gonna add that on as a modifier to this cpt code modifier r t so now this case is fully coded out we have our diagnosis of g five six point zero one and then our cpt six four seven two one with the rt modifier and then we're going to enter this into our billing system and send it out to insurance for payment now this case i want to show you because it demonstrates a little bit how you have to think a little bit further with medical coding that the diagnosis lookup is not going to always be exceptionally straightforward so in this particular case we have a patient that is coming for a colonoscopy screening this is a 55 year old female who is having a colonoscopy to screen we're doing a screening screening because there's different types of colonoscopies there's diagnostic and there are screening colonoscopies so diagnostic is we're going to diagnose something screening is we're just looking to see if there is anything there is no family history that's going to come into play no family history of colon cancer has been no blood in the school so there's no symptoms here this is just gener this is truly a screening colonoscopy the patient isn't having any symptomology there's no high risk so it's just a screening colonoscopy and again procedure performed we don't just want to code just based off this we can use it as a good jumping off point but we want to always verify in this procedure note this body of the operative report as i call it so colonoscopy to screen for colon cancer here's the prep they did fentanyl and then we did the tip of the endoscope so that endoscope is that long scope that has a little camera on it so they can see as they're going in and the scope wasn't introduced into the rectum retroflexion of the tip of the endoscope failed to reveal any distal rectal lesion so that means there wasn't any little little lumps or bumps or any tumors that they found in there sounds like there was a good clean uh good clean screening colonoscopy the rest of the colon through the cecum was well visualized good the sql strap ileocecal valve and light reflex in the right lower quadrant were all identified there was no evidence of tumor polyp mass ulceration or any other focus of inflammation adverse reactions none impression normal colonic mucosa through the to the cecum there was no evidence of tumor or polyp so good so this was an encounter for screening uh colon cancer so now we're going to need our diagnosis right so what's our diagnosis and then our cpt code so what's going to be our diagnosis here because this patient didn't have any symptoms we didn't find anything right we didn't find a mass we didn't find an ulcer there's no polyps they didn't have a family history so what are we coding here well this is something that we call an encounter for so it is an encounter for screening colonoscopy so in this case there isn't really a diagnosis but we have a status code so we have these z codes that are status codes they're things like you have a family history of something you're at higher risk of having a disease you are receiving an encounter for your routine physical and encounter for a gyn physical and in this case this was an encounter to screen for colon cancer so we're going to start with our encounter this was an encounter to screen we might also find it under the word screening those are some some of the words that i'm thinking of that we should start looking at when we're trying to find this in the alphabetic index so we're going to start with encounter so here are our encounters and if we go to encounter and then we go to our next indentation so we have adjustment we have administrative purposes we have antinatal screening we have assisted reproduction breast implants oh wait here we go colonoscopy screening z12.11 now i'm going to write that down so that i don't forget it so z12.11 and i'm going to verify that in my tabular list we always verify in the tabular list so here we go encounter for screening for malignant neoplasms and this is z12.11 encounter for screening for malignant neoplasms of the colon and that's what we were doing the screening for to make sure that they don't have colon cancer but there's a little note here what does it say use additional code to identify any family history of malignant neoplasm well this patient it says here they had no family history so we don't have to add that in because there was no family history so this is the rank code z 12.11 now cpt how do we find that one so let's check our index in the back and we'll just look at colonoscopy because that seems like the most obvious thing to look for right so when we look at colonoscopy there's all different types there's flexible and then there's the ablations we didn't do ablations we didn't do biopsies placement of a stent i'm actually not seeing a screening code isn't that interesting but maybe we could find something around where these codes are so let's do this one where we go to the digestive system and look it up that way so usually with these chapters they kind of start at the top meaning start at the head and then go to the feet so lips tongue and colon will probably be towards the end so here we are colon incision excision destruction endoscopy that's what we did endoscopy that's going to be page 368 so we have proctored sigmoidoscopies so colonoscopy flexible diagnostic including collection of specimen by brushing or washing when performed separate procedure so this is when performed so that when performed means we don't have to do it but when we perform it that is included so let's actually this is a great tool is the colonoscopy decision tree so decision to undergo colonoscopy is this diagnostic or therapeutic it is diagnostic um we went let's see did we reach the does not reach splenic lecture beyond splendid flexure or to the cecum so let's go back here did we reach the cecum in this case we did the rest of the column through the cecum was well visualized so that's it so this is what we're doing here we have this one to the cecum colonoscopy four five three seven eight so that's the code we're gonna use four five three seven eight now the other thing to consider with this is that depending on this patient's insurance they might have different codes so if this is a medicare patient medicare has their own screening colonoscopy codes so those codes are not found in your cpt book they're actually found in your hicpix book and they are g codes so if you look here in your hicpix book this is the codes for colonoscopy cancer screening and they want to differentiate for medicare patients is this a patient at high risk or patient not high risk now high risk would be like they have a personal history or family history this patient didn't so we would code this as a g0121 not at high risk for this patient if they have medicare so medical coding is not just looking up the term finding it in the alphabetic index there is some analytics involved to appropriately map them to the right code and verification and then even being able to identify deficiencies and communicate those with providers i hope you found the hands-on demonstration helpful now do you need more practice because if so i have got you covered check the link in the description below so you can download my free beginner practice sheets so what questions do you still have about medical coding because i want to know what your burning questions are what i didn't cover that maybe i can cover in future videos definitely let me know in the comments below guys don't forget to like share and subscribe i will see you guys in the next video and until then just keep on coding on
