Welcome to the world of medical billing and coding! No other job in the medical field affects more lives than this one because everyone involved in the healthcare experience, from the patient and front office staff to providers and payers, relies on you. You are, so to speak, the touchstone in the medical industry.
A lot rests on your shoulders as the biller and coder. With this responsibility comes great power, and that power must be treated with respect and integrity. In this chapter, I take you on a very brief tour of what medical billing and coding entails. I hope you find, as I have, that working as a medical biller/coder is a challenging and rewarding job that takes you right into the heart of the medical industry.
Coding versus Billing: They Really Are Two Jobs
Although many people refer to billing and coding as if it were one job function (a convention I use in this book unless I’m referring to specific functions), billing and coding really are two distinct careers. In the following sections, I briefly describe the tasks and functions associated with each job and give you some things to think about to determine which path you want to pursue:
The medical coder deciphers the documentation of a patient’s interaction with a healthcare provider (physician, surgeon, nursing staff, and so on) and determines the appropriate procedure (CPT) and diagnosis code(s) (ICD) to reflect the services provided.
The medical biller then takes the assigned codes and any required insurance information, enters them into the billing software, and then submits the claim to the payer (often an insurance company) to be paid. The biller also follows up on the claim as necessary.
Both medical billers and coders are responsible for a variety of tasks, and they’re in constant interaction with a variety of people (you can read about the various stakeholders in Part 5). Consider these examples:
Because they’re responsible for billing insurance companies and patients correctly, medical billers have daily interaction with both patients and insurance companies to ensure that claims are paid correctly in a reasonable time.
To ensure coding accuracy, coders often find themselves querying physicians regarding any questions they may have about the procedures that were performed during the patient encounter and educating other office staff on gathering required information.
Billers (but sometimes coders, too) have the responsibility for explaining charges to patients, particularly when patients need help understanding their payment obligations, such as coinsurance and copayments, that their insurance policies specify.
When submitting claims to the insurance company, billers are responsible for verifying the correct billing format, ensuring the correct modifiers have been appended, and submitting all required documentation with each claim.
In short, medical billers and coders together collect information and documentation, code claims accurately so that physicians get paid in a timely manner, and follow up with payers to make sure that the money finds its way to the provider’s bank account. Both jobs are crucial to the office cash flow of any healthcare provider, and they may be done by two separate people or by one individual, depending upon the size of the office.
For the complete lowdown on exactly what billers and coders do, check out Chapter 2 for general information and Part 4, which provides detailed information on claims processing.
Following a Day in the Life of a Claim
When you’re not interfacing with the three Ps — patients, providers, and payers — you’ll be doing the meat and potatoes work of your day: coding claims to convert provider performed services into revenue.
Claims processing refers to the overall work of submitting and following up on claims. Here in a nutshell is the general process of claims submission, which begins almost as soon as the patient enters the provider’s office:
The patient hands over her insurance card and fills out a demographic form at the time of arrival.
The demographic form includes information such as the patient’s name, date of birth, address, Social Security or driver’s license number, the name of the policyholder, and any additional information about the policyholder if the policyholder is someone other than the patient. At this time, the patient also presents a government-issued photo ID so that you can verify that she is actually the insured member.
Warning Using someone else’s insurance coverage is fraud. So is submitting a claim that misrepresents an encounter. All providers are responsible for verifying patient identity, and they can be held liable for fraud committed in their offices.
After the initial paperwork is complete, the patient encounter with the service provider or physician occurs, followed by the provider documenting the billable services.
The coder abstracts the billable codes, based on the physician documentation.
The coding goes to the biller who enters the information into the appropriate claim form in the billing software.
After the biller enters the coding information into the software, the software sends the claim either directly to the payer or to a clearinghouse, which sends the claim to the appropriate payer for reimbursement.
If everything goes according to plan, and all the moving parts of the billing and coding process work as they should, your claim gets paid, and no follow-up is necessary. For a detailed discussion of the claims process from beginning to end, check out Chapters 11, 12, and 13.
Of course, things may not go as planned, and the claim will get hung up somewhere — often for missing or incomplete information — or it may be denied. If either of these happens, you must follow up to discover the problem and then resolve it. Chapter 14 has all the details you need about this part of your job.
Keeping Abreast of What Every Biller/Coder Needs to Know
If you’re going to work in the medical billing and coding industry (and you will!), you must familiarize yourself with three big must-know items: compliance (following laws established by federal or state governments and regulations established by the department of HHS or other designated agencies), medical terminology (the language healthcare providers use to describe the diagnosis and treatment they provide), and medical necessity (the diagnosis that makes the provided service necessary). In the following sections, I introduce you to these concepts. For more information, head to Part 2.
Complying with federal and state regulations
In the United States, as in many countries, healthcare is a regulated industry, and you have to follow certain guidelines. In the United States, these rules are enforced by the Office of Inspector General (OIG). The regulations are designed to prevent fraud, waste, and abuse by healthcare providers, and as a medical biller or coder, you must familiarize yourself with the basics of compliance.
Being in compliance basically means an office or individual has established a program to run the practice under the regulations as set forth by federal or state governments and the department of HHS or other designated agencies.
You can thank something called HIPAA for setting the bar for compliance. The standard of securing the confidentiality of healthcare information was established by the enactment of the Health Insurance Portability and Accountability Act (HIPAA). This legislation guarantees certain rights to individuals with regard to their healthcare. Check out Chapter 4 for more info on compliance, HIPAA, and the OIG.
Learning the lingo: Medical terminology
Everyone knows that doctors speak a different language. Turns out that that language is often Latin or Greek. By putting together a variety of Latin and Greek prefixes and suffixes, physicians and other healthcare providers can describe any number of illnesses, injuries, conditions, and procedures.
As a coder, you need to become familiar with these prefixes and suffixes so that you can figure out precisely what procedure codes to use. By mastering the meaning of each segment of a medical term, you’ll be able to quickly make sense of the terminology that you use every day.
You can read about the most common medical prefixes and suffixes in Chapter 5.
Demonstrating medical necessity
Before a payer (such as an insurance company) will reimburse the provider, the provider must show that rendering the services was necessary. Setting a broken leg is necessary, for example, only when the leg is broken. Similarly, prenatal treatment and newborn delivery is necessary only when the patient is pregnant.
To demonstrate medical necessity, the coder must make sure that the diagnosis code supports the treatment given. Therefore, you must be familiar with diagnosis codes and their relationship to the procedure codes. You can find out more about medical necessity in Chapter 5.
Remember Insurance companies are usually the parties responsible for paying the doctor or other medical provider for services rendered. However, they pay only for procedures that are medically necessary to the well-being of the patient, their client. Each procedure billed must be linked to a diagnosis that supports the medical necessity for the procedure. All diagnoses and procedures are worded in medical terminology.
Deciding Which Job Is Right for You
If you think the idea of working with everyone from patients to payers sounds good and working a claim through the billing and coding process seems right up your alley, then you can start to think about which particular jobs in the field might be a good fit for you. Luckily, you have lots of options. You just need to know where to look and what kind of job is right for you. I give you some things to think about in the following sections.
Examining your workplace options
Before you crack open the classifieds, give some thought to what sort of environment you want to work in. You can find billing and coding work in all sorts of places, such as
Physician offices
Hospitals
Nursing homes
Outpatient facilities
Billing companies
Home healthcare services
Durable medical good providers
Practice management companies
Federal and state government agencies
Commercial payers
Which type of facility you choose depends on the kind of environment that fits your personality. For example, you may want to work in the fast-paced, volume-heavy work that’s common in a hospital. Or maybe the controlled chaos of a smaller physician’s office is more up your alley.
Other considerations for choosing a particular area include what you can gain from working there. A larger office or a hospital setting is great for new coders because you get to work under the direct supervision of a more experienced coding staff. A billing company that specializes in specific provider types lets you become an expert in a particular area. In many physician offices, you get to develop a broader expertise because you’re not only in charge of coding, but you’re also responsible for following up on accounts receivable and chasing submitted claims.
To find out more about your workplace options and the advantages and disadvantages that come with each, head to Chapter 3.
Thinking about your dream job
Although you can’t predict the future, you can begin to put some thought into your long-term career goals and how you can reach them. Here are some factors to consider when thinking about what kind of billing/coding job you want:
The kind of job you want to do and the tasks you want to spend your time performing: Refer to the earlier sections "Following a Day in the Life of a Claim and
Keeping Abreast of What Every Biller/Coder Needs to Know" for more job-related tasks. Chapter 2 has a complete discussion of billing and coding job functions.
Where you plan to seek employment and in what kind of setting: The preceding section gives you a quick idea of what your options are. Chapter 3 gives you more detail.
The type of certification potential employers prefer and the time commitment involved: Many billing or practice management companies, for example, are contractually obligated to their clients to employ only certified medical coders to perform the coding.
The type of training program(s) available in your area: Many reputable training programs are associated with the two main biller/coder credentialing organizations, the AAPC (American Academy of Professional Coders) and AHIMA (American Health Information Management Association), each of which tends to focus on a particular area. AAPC certification is generally associated with coding in physicians’ offices, but it has recently updated its courses and now offers certification in both hospital inpatient and outpatient coding; AHIMA certification is generally associated with hospital coding. For information about finding a training program and your options, head to Chapter 8.
Tip Take a few minutes (or hours!) now to think over these points. Trust me: It’s time well spent before you jump on the billing and coding bandwagon.
Prepping for Your Career: Training Programs and Certifications
Breaking into the billing and coding industry takes more than a wink and a smile (though I’m sure yours are lovely). It takes training from reputable institutions and certification from a reputable credentialing organization. The next sections have the details.
Previewing your certification options
To score a job as a biller and coder, you should get certified by a reputable credentialing organization such as the American Health Information Management Association (AHIMA) or the AAPC (American Academy of Professional Coders). In Chapter 7, I tell you everything you need to know about these organizations. Here’s a quick overview:
AAPC is the credentialing organization that offers Certified Professional Coder (CPC) credentials, as well as a myriad of other credentials. AAPC training focuses on physician offices, practice management, compliance, auditing, billing, and inpatient and outpatient hospital-based coding.
AHIMA coding certifications — Correct Coding Specialist (CCS) and Certified Coding Associate (CCA) — are intended to certify the coder who has demonstrated proficiency in inpatient and outpatient hospital-based coding, while the Correct Coding Specialist—Physician-based (CCS-P) is, as its name indicates, for coders who work for individual physicians.
All sorts of other specialty certifications are also available, which you can read more about in Chapter 10.
Tip To choose which certification — AHIMA or AAPC — best fits your career goals, first think about the type of training program you want. Second, examine your long-term career goals. What kind of medical billing and coding job do you ultimately want to do, in what sort of facility do you want to work, and how do you want to spend your time each day?
Remember To get certified, you must pass an exam administered by the credentialing organization. Head to Chapter 9 for exam details and information on how to sign up for one.
Going back to school
Sharpen your pencils, get a sweet new backpack, and shine up an apple for the teacher because you’re going back to school. That’s right, school. It’s your first stop on the way to Medical Billing and Coding Land. The good news is that medical coding or billing is one of the few medical careers with fewer education requirements. Translation: You won’t be spending decades preparing for your new career. Most billing and coding programs get you up and running in a relatively short amount of time, often less than two years.
Remember After you successfully complete a training program, you receive a certificate of completion. Note that this is different from achieving certification. To get your certification, you still have to take certification exams offered by the credentialing bodies after graduation. Fortunately, a solid medical coding and billing program provides you with the knowledge necessary to ace the exams and gain entry-level certification. Most programs offer training in the following:
Human anatomy and physiology
Medical terminology
Medical documentation
Medical coding, including proper use of modifiers
Medical billing
Claims filing
Medical insurance, including commercial payers and government programs
You can read all about your educational options — from abbreviated study programs to more inclusive extended programs — in Chapter 8, where I highlight the advantages of some programs and the pitfalls of others.
Planning for the Future
As soon as you get your first billing and coding job — and probably even before that — you’ll start hearing about something called ICD-10, which is the tenth revision of the International Classification of Diseases (hence, the ICD), the common system of codes used by the World Health Organization (WHO) that classifies every disease or health problem you code. These diagnosis codes represent a generalized description of the disease or injury that was the catalyst for the patient/physician encounter. As a biller/coder, you use the ICD every day.
ICD codes are also used to classify diseases and other health problems that are recorded on many types of health records, including death certificates, to help provide national mortality and morbidity rates. ICD-10 went into place October 1, 2015. Before that, the ninth edition of the ICD classification (ICD-9) had been used in the United States since 1979. Now, ICD-11 is on the horizon and is tentatively scheduled for a January 2022 release.
Technical stuff WHO uses the data gleaned from your coding to analyze the health of large population groups and monitor diseases and other health problems for all members of the global community. For your purposes, you can think of the ICD codes as the language you speak when coding so that organizations like WHO can do the work of keeping the world healthy.
The transition to ICD-10 increased the demand for medical coders due to the increased specificity. The healthcare workforce is predicted to continue growing, which should increase the demand for billing and coding professionals for the foreseeable future.

Exploring the Billing and Coding Professions
IN THIS CHAPTER
check Understanding how medical coding differs from medical billing
check Looking at the tasks that billers and coders must perform
check Determining which job is best for you
Medical billing and coding specialists are the healthcare professionals responsible for converting patient data from treatment records and insurance information into revenue. They take all that complicated information and turn it into a language of codes the insurance companies and other payers can understand. The healthcare industry depends on qualified medical billers and skilled medical coders to accurately record, register, and keep track of each patient’s account so that the docs get paid and the patients get charged only for services they receive.
Although they’re frequently clumped together, medical billing and medical coding are actually two distinct jobs. In this chapter, I discuss each separately.
Note: In this chapter, I offer a very brief overview of the tasks that billers and coders perform. For a detailed discussion of the billing and coding process, head to Part 4.
Looking at the Medical Coding Job
The coder’s job is to extract the appropriate billable services from the documentation that has been provided. The coder is given the office notes and/or the operative report as dictated by the physician. From this documentation, the coder identifies any and all billable procedures and assigns the correct diagnosis and procedure codes. The coder also identifies whether a procedure that is often included with another procedure should be billed on its own (or, in coder-speak, unbundled) to allow for additional reimbursement. To be eligible for unbundling, the documentation must indicate that extra time and effort was required or that a procedure that is normally included in the primary procedure was done at a separate site or time and was necessary to ensure a positive outcome for the patient.
Remember That’s the nuts-and-bolts stuff. To do the job of medical coder well, however, you must be aware that medical coding requires a daily commitment to remaining ethical despite pressures from employers who are looking at the bottom line and don’t understand the laws and procedural mandates a coder must follow. I have heard physicians tell coders to just use the code with the highest revenue potential. This philosophy may be what is best in the short term for the provider’s bottom line, but when an auditor comes around to investigate, that money is going back with interest. So the first order every day for the coder is to be mindful of her ethical duty to the profession, physicians, and patients.
The key to optimal reimbursement is full documentation by the provider (the physician, for example, who sees the patient and performs the procedure) coupled with full extraction, or identification, of billable procedures by the coder. Everyone — from the doc to you, the coder — has to dot every i and cross every t.
In the following sections, I take you through the different tasks you’ll perform as you prepare claims for reimbursement.
Verifying documentation
As noted earlier, the job of coder starts with the documentation provided by the physician. This documentation can take the form of an operative report or an office note.
Remember Physicians are trained to document their work, so consider them partners in the coding enterprise. They (or a member of their staff) note all the information needed to treat a particular patient before the paperwork hits the coder’s desk.
Checking operative reports
An operative report is the document that is transcribed from the physician’s dictation of the patient encounter. It describes in detail exactly what was done during a surgery. Operative reports are normally set into a template, which serves as an outline that identifies the reason for the procedure, what illness or injury was confirmed during the procedure, and finally the procedure(s) that were performed.
The basic format of an operative report includes the following:
Patient name and date of birth
Operating physician
Assistant at surgery
Date of service
Preoperative diagnosis (the diagnosis based on the examination and preoperative testing)
Postoperative diagnosis (new diagnoses based on what the doctor found during the surgery)
Procedure(s) performed (an outline of the procedures done)
Body of the operative report (a description of everything that was stated in the postoperative diagnosis and procedure performed sections)
Put simply, verifying documentation is a fact-checking gig. Here’s what you need to check:
That procedures stated as performed in the heading of the operative report are substantiated in the body of the report.
The diagnosis provides medical necessity for the procedure and that the procedure(s) listed in the outline are documented in the body of the operative report. Medical necessity is simply the reason for the visit or surgery; it defines the disease process or injury (head to Chapter 5 for details). Before payers reimburse the provider, they have to know why the visit was necessary.
As a coder, you rely on the information in the body of the operative report to verify the documentation. If the body doesn’t support the rest of the operative report (the operative report doesn’t mention a procedure listed in the procedures performed
section, for example, or the description isn’t detailed enough), then you’re responsible for asking the surgeon to clarify.
Remember If the doctor doesn’t say it in the operative report, regardless of how obvious it seems, it is the same as if it was not done, because per coding guidelines, it cannot be coded or billed.
Checking office notes
All physician services are coded and billed based upon physician documentation. When coding office procedures or verifying the level of evaluation and management code that is appropriate for the visit, you rely on the physician’s office notes. An office note typically documents the patient’s symptoms, the physician’s findings, and the plan for treatment, including a follow-up plan.
Warning If you believe that a higher level of service was performed, asking a physician for clarification is certainly acceptable, but coding a procedure that’s not documented is not acceptable. Coding is not a job for those who like to second-guess. You can’t assume you know what the doctor meant or intended and code based on your assumptions. Therefore, make sure you add clarifying information
to your list of daily jobs as a coder.
IT’S A BIRD! IT’S A PLANE! IT’S SUPER-BILL!
A super-bill is a form created specifically for an individual office or provider. It normally is prepopulated with the patient’s demographic information, including insurance copay, and contains the most common diagnosis and procedural codes used by the office. It may also have a section that indicates the need for follow-up appointments and should also have a space for the physician’s signature.
The super-bill is a great tool for the provider for billing purposes and also proves helpful for keeping track of each patient’s visit. In many offices, the super-bill has been replaced by the electronic health record (EHR), an all-electronic method of patient record keeping.
Super-bills, wonderful as they are, can also be the bane of the coder’s existence. Although checking off billable procedures is certainly easier for the provider, they may overlook adding the detail necessary to support the procedures (and level of the visit) indicated on the bill. If the chart doesn’t match the super-bill, it’s back to square one for the coder.
Following up on unclear documentation
As I explain in the preceding sections, the physician documents all procedures he performs. If he doesn’t state a procedure in his dictation (in his operative report) or note it in the physician’s notes, regardless of how obvious it may seem, it was not done.
Remember The chant of the medical coder always comes in handy. When in doubt or faced with incomplete documentation, remember: If the doctor didn’t say it, it wasn’t done.
Period.
When the documentation is missing or ambiguous, it’s your responsibility to clarify with the physician. Although some physicians become defensive or irritated when the coder questions the documentation, those who understand that your questions can maximize their reimbursement will gladly amend the documentation to clear up the problem.
Assigning diagnosis and procedure codes
Time to play Name that Illness!
Upon reading the operative report or office notes, you must identify the illness or disease and find the corresponding International Classification of Diseases (ICD) diagnosis code.
