CPC is AAPC's flagship credential and the dominant certification in physician practice and outpatient coding. It has no mandatory degree requirement, and the exam is 100 questions over four hours, taken with code books open, at approximately $399 including one retake plus annual membership. Candidates who pass without two years of experience receive the CPC-A apprentice designation, which is removed through documented experience or a qualifying externship. The exam is open book but time constrained, and most failures come from navigation speed rather than knowledge. CPC is the right credential if you are targeting physician groups and ambulatory settings; CCS is the right one for hospital inpatient coding.
The apprentice A on CPC-A is the part nobody explains before you pay. You can pass the exam and still be screened out of jobs, because employers read CPC-A as unproven and many postings filter it. That is not a reason to avoid the credential, it is a reason to plan the removal of the A from the day you register: line up an externship or a qualifying position first, so the designation drops as fast as possible rather than sitting on your resume for two years.
CPC certifies coding competence in physician and outpatient settings, focused on CPT procedure coding, ICD-10-CM diagnosis coding, and HCPCS Level II, along with the payer rules and documentation requirements governing professional services billing.
Its market position is clear and worth understanding before choosing between credentials. AAPC is the larger organization by membership and dominates the physician practice, ambulatory, and billing company segment. AHIMA credentials dominate hospital settings. Neither is superior in the abstract, and the correct choice follows from the setting you intend to work in.
The exam is open book, which candidates consistently misinterpret as easy. It is not. You have four hours for 100 questions requiring you to locate and apply codes across three separate manuals, which averages under two and a half minutes per question including lookup. Candidates fail this exam on speed far more often than on knowledge.

Who is eligible
Eligibility is the first thing to verify, because in this field it is frequently the binding constraint rather than the exam itself. Confirm current requirements with AAPC directly before planning around them.
- No mandatory degree requirement
- AAPC recommends an associate degree and coding education before attempting
- Two years of coding experience removes the apprentice (CPC-A) designation, as does a combination of education and externship
What the exam covers
The domains below reflect the published content areas for this credential. Weighting shifts between exam versions, so treat this as a map of the territory rather than a fixed blueprint, and check the current outline with the issuing organization.
| Domain | What it covers |
|---|---|
| CPT procedure coding | Surgery by body system, evaluation and management services, anesthesia, radiology, pathology and laboratory, and medicine sections. |
| ICD-10-CM diagnosis coding | Diagnosis code selection and specificity for outpatient and professional services, including guideline application. |
| HCPCS Level II | Supplies, drugs, durable medical equipment, and the modifiers that determine whether a claim is paid. |
| Anatomy, physiology, and medical terminology | The biomedical foundation required to interpret operative and clinical documentation correctly. |
| Compliance and regulatory | Fraud and abuse, medical necessity, the National Correct Coding Initiative, and payer policy. |
| Coding guidelines and practice management | Official guidelines, modifier usage, bundling rules, and the documentation requirements behind professional billing. |
The apprentice designation, explained properly
This is the part of CPC that most surprises new coders, and understanding it before you register saves real frustration.
If you pass the exam without two years of documented coding experience, you are awarded CPC-A rather than CPC. The A denotes apprentice. It is removed once you document two years of experience, or one year plus completion of a qualifying education and externship route that AAPC recognizes.
It matters because employers read it. Many postings screen for CPC and treat CPC-A as unproven, which creates the familiar problem of needing experience to remove a designation that is making it harder to get experience.
The way through is to plan for it in advance. Take the qualifying externship route if it is available to you, seek any role that produces documentable coding experience even at lower pay, and treat the first year as an apprenticeship in fact as well as in title. Coders who plan this from the start remove the A in about a year rather than two.
Preparing for an open book exam
The open book format changes what preparation should look like, and candidates who prepare as though it were a closed book exam waste most of their study time.
Book navigation is the primary skill. You need to find the right section of CPT within seconds, know where the guidelines sit within each section, and have your manuals tabbed and annotated to your own system well before exam day. Speed here is entirely a function of practice.
Time management is the second. At under two and a half minutes per question, there is no room to labor over a difficult item. Successful candidates triage: answer what is quick, mark what is slow, and return. Practicing under strict time is not optional preparation for this exam, it is the main preparation.
Evaluation and management coding deserves disproportionate attention. It is heavily represented, the rules changed substantially in recent years, and it is the area where experienced candidates most often carry outdated assumptions.
- Tab and annotate your own code books, and use those exact books in every practice session.
- Practice under strict time. Speed is the constraint, not knowledge.
- Study evaluation and management coding heavily, and make sure your sources reflect current guidelines.
- Learn modifiers properly, because they are heavily tested and drive whether claims are paid.
- Use the included free retake as a planning assumption rather than a failure. It exists because many candidates use it.
Total cost of the credential
The exam is approximately $399 and includes one free retake, which is a meaningful difference from AHIMA exams where a retake is charged separately. AAPC membership is required and runs roughly $200 annually.
Code books are a genuine recurring cost. CPT, ICD-10-CM, and HCPCS are updated annually and current editions typically run $250 to $400 for the set. You need current books for the exam and, if you code professionally, every year afterward.
Ongoing membership and continuing education are also recurring, at 36 CEUs every two years. Factor the annual cost into the comparison with AHIMA credentials, which have lower ongoing membership requirements but charge separately for retakes.
What this credential is worth
Certification moves compensation in health information more than degree level, employer, or geography. Our 2026 survey of 1,127 graduates found 87% of employers required RHIA or RHIT for health information positions, and that requirement is usually enforced automatically by applicant tracking systems before a human reads the application.
That mechanism is the reason credentials matter so much here. An uncredentialed candidate is not paid less for the same job. They are excluded from the job and end up in a lower band of roles entirely. For a full breakdown of pay by credential, see our HIM Salary Guide 2026.
Should you pursue it
- If you are targeting physician practices, ambulatory settings, or billing companies, CPC is the credential those employers screen for.
- If you are targeting hospital inpatient coding, choose CCS instead. The credentials are not interchangeable in employer screening.
- Plan the removal of the apprentice designation before you sit the exam, through an externship or any role producing documentable experience.
- Practice under strict time with your own tabbed code books. This exam is lost on navigation speed more than on knowledge.
What this means for you
Credentials in health information work differently from credentials in most fields, and understanding the mechanism changes how you should sequence them. They are not primarily a signal of what you know. They are what gets your application read at all.
Our 2026 survey of 1,127 graduates found 87% of employers required RHIA or RHIT for health information positions. In practice that is enforced by an applicant tracking system matching on a credential string, which means an uncredentialed candidate is filtered before a human sees the application. The consequence is that credentials do not earn you a premium for identical work. They determine which band of roles you are eligible for at all, and the bands are far apart.
For context on the compensation those bands represent, the federal reference for the occupation most graduates enter is a $51,140 national median for Medical Records Specialists, SOC 29-2072, per BLS Occupational Employment and Wage Statistics, May 2025. That occupation blends entry clerical roles with credentialed specialists and excludes management entirely, which is precisely why it understates a credentialed career and why we publish our own survey figures alongside it.
Three practical rules follow. Verify your eligibility before you plan around a credential, because in this field eligibility is usually the binding constraint rather than the exam. Ask your employer to fund it before you self fund, because most do and it is a straightforward request at hire or at review. And sit the exam while the material is still loaded, since pass rates are meaningfully higher for candidates who test within six months of completing relevant coursework. Our full research findings set out the evidence.

Frequently asked questions
What is CPC certification?
CPC stands for Certified Professional Coder, AAPC's flagship credential for physician and outpatient coding. It covers CPT procedure coding, ICD-10-CM diagnosis coding, HCPCS Level II, modifiers, and the compliance rules governing professional services billing.
What does CPC-A mean?
The A denotes apprentice and is assigned to candidates who pass the exam without two years of documented coding experience. It is removed by documenting two years of experience, or one year plus a qualifying education and externship route. Many employers screen against CPC-A, so planning its removal in advance matters.
How much does the CPC exam cost?
Approximately $399, which includes one free retake, plus AAPC membership of roughly $200 annually. Current code books add $250 to $400 and must be repurchased annually if you code professionally. The included retake is a genuine advantage over exams that charge separately for it.
Is the CPC exam hard?
It is open book, which misleads candidates into underestimating it. The real constraint is time: 100 questions in four hours with lookups across three manuals averages under two and a half minutes per question. Most failures are due to navigation speed rather than knowledge gaps.
CPC or CCS, which is better?
Neither is better in the abstract. CPC dominates physician practice and outpatient coding; CCS dominates hospital inpatient coding and is associated with the higher end of coding pay. Decide the setting you want to work in and take the credential that setting screens for.
Do you need a degree for CPC?
No mandatory degree is required, though AAPC recommends an associate degree and coding education first. Be aware that skipping accredited education also means you are not RHIT-eligible, which closes off hospital roles and the supervisory track. Many coders hold both RHIT and a coding credential for exactly this reason.
How long does it take to get CPC certified?
Typically four to eight months of preparation for candidates with a coding education, longer without one. Removing the apprentice designation takes an additional one to two years depending on whether you use the externship route, so plan for roughly two years to a clean CPC.
