AAPC certification
How to Become a Certified Professional Biller (CPB) in 2026
To become a Certified Professional Biller (CPB) you pass the CPB exam set by AAPC. The billing-side credential, covering claim submission, denials, appeals, and payer rules.
On cost, exam vouchers start at $425, and AAPC's prep course starts at $1,495.
There is no licence and no state board in medical coding, so the credential is the qualification. What follows is what the CPB covers, what it costs in total, who can sit it, what keeps it current, and when it is the right one to choose over CPC or COC.

What is the CPB certification?
The CPB, or Certified Professional Biller, is a certification awarded by AAPC that validates expertise in the medical billing process: claim submission, payment posting, insurance guidelines and revenue cycle workflows. In practice it is the credential for the other half of the job, and the right one if the work you want is claims rather than charts.
AAPC points the CPB at three groups in particular:
- People entering healthcare through billing rather than coding
- Experienced billers validating what they already do
- Revenue cycle staff strengthening their payer knowledge
What does the CPB exam cover?
The CPB exam covers 5 areas, as AAPC describes them:
- The healthcare revenue cycle and payer reimbursement fundamentals
- Claim submission for commercial payers, Medicare and Medicaid
- Coordination of benefits, medical necessity and prior authorisation
- Identifying claim errors, preparing appeals and managing resubmissions
- HIPAA privacy and security in billing workflows, and fraud prevention
What that means in practice: denials are the centre of gravity. Claim submission is the easy half; the weight sits on why claims fail, how appeals are constructed and how payer rules differ, which is what the job is actually spent on.
How much does the CPB exam cost?
The CPB exam costs exam vouchers start at $425, and AAPC's prep course starts at $1,495. Nothing else is included in that figure: expect to buy the current code books, and to pay tuition separately if you take a programme.
The CPB is taken online at home with a live remote proctor, or at a testing centre.
Compare that with tuition before deciding it is expensive. Programmes we rank charge between about $1,100 and $10,100 a year, so the exam fee is a small share of what you will actually spend getting to it. See the ranked programmes.
Who can sit the CPB exam?
Anyone meeting AAPC's stated conditions can sit the CPB. AAPC expects candidates to bring high-level knowledge of medical terminology, anatomy and pathophysiology, together with payer policies, compliance rules and the CPT, HCPCS Level II and ICD-10-CM code sets.
Meeting it is not the same as being ready for it. AAPC is describing who may register, not who tends to pass, and the gap between those two is where most failed first attempts sit. A programme built specifically around the CPB is worth more than one that merely leaves you eligible for it, which is why our ranked programmes record the exam each one names.
How do you keep the CPB?
Keeping the CPB takes an active AAPC membership plus 36 continuing education units every two years. Worth pricing in before you choose: lapse it and you pay the full exam fee again to recover it.
What sets the CPB apart
- The billing credential rather than a coding one, which matters because billing-only roles sit in a different, lower-paid federal occupation
- The only AAPC credential centred on denials, appeals and collections rather than on code assignment
How does the CPB compare with other coding certifications?
The CPB compares most directly with CPC and COC, and the choice between them follows the employer rather than the credential. The CPB is the credential for the other half of the job, and the right one if the work you want is claims rather than charts.
| Credential | Body | Where it fits |
|---|---|---|
| CPC | AAPC | the default first credential for physician-practice and outpatient work, and the foundation the other AAPC credentials build on |
| COC | AAPC | the facility-side counterpart to the CPC, for people whose employer is a hospital outpatient department rather than a practice |
| CIC | AAPC | AAPC's answer to the inpatient hospital market, where AHIMA's CCS has the longer history |
| CCA | AHIMA | AHIMA's entry credential, and the usual first exam for a graduate of a PCAP-approved certificate |
| CCS | AHIMA | the inpatient hospital standard, and the credential most worth working toward if acute care is the goal |
What jobs and pay does the CPB lead to?
The CPB leads to medical biller roles. Federal data files that work as Billing and Posting Clerks, SOC 43-3021, with a median of $48,500 , with the bottom tenth at $37,290 and the top tenth at $67,710, per the U.S. Bureau of Labor Statistics for May 2025. Pay follows experience and setting more than it follows any single credential, and the lower percentiles are where new entrants sit.
