About this exam

The Certified Professional Biller (CPB) is a credential offered by AAPC that validates expertise in the medical billing process. According to AAPC, earning the CPB demonstrates proficiency in claim submission, payment posting, insurance guidelines, and revenue cycle workflows that ensure healthcare providers are reimbursed accurately and on time. The credential is aimed at new entrants to healthcare who want to launch a billing career, experienced but uncertified billers seeking to validate their skills and increase earning potential, revenue cycle professionals strengthening their billing and payer knowledge, and healthcare staff transitioning into billing from administrative or support roles. The exam covers four areas: core billing knowledge (revenue cycle fundamentals, claim submission for commercial payers, Medicare and Medicaid, payer guidelines, edits, and clean claim requirements); insurance and payer requirements (plan types, coverage rules, coordination of benefits, medical necessity, prior authorization); denials, appeals, and collections (correcting claim errors, appeals, resubmissions, payment posting and reconciliation); and compliance and regulatory standards (HIPAA privacy and security in billing workflows, fraud and abuse prevention, CMS and payer-specific billing guidelines). AAPC states that candidates need a high-level knowledge of medical terminology, anatomy, and pathophysiology, plus payer policies, compliance rules, healthcare regulations, CPT, HCPCS Level II, and ICD-10-CM codes; prerequisite courses are offered for those without billing experience or working knowledge of these subjects. Preparation options include self-paced and virtual instructor-led CPB exam prep courses, and the exam can be scheduled online with a live remote proctor or at a testing center.

What you'll study

Common questions

About CPB Medical Billing preparation

What is the CPB exam format?

AAPC lists the CPB exam as multiple choice and lets you choose to take it online at home with a live remote proctor or at a testing center. Purchase an exam voucher to view available dates and times. The source does not publish the question count or time limit, so confirm those details with AAPC when you schedule.

How much does the CPB exam cost?

AAPC lists exam vouchers starting at $425. That is a starting price, so the amount you pay can vary by option or membership status. Exam prep training is separate: self-paced and virtual instructor-led CPB courses start at $1,495. Budget for both the voucher and any training you choose.

Do I need billing experience to sit for the CPB exam?

AAPC states that candidates need a high-level knowledge of medical terminology, anatomy, and pathophysiology, along with understanding of payer policies, compliance rules, healthcare regulations, and CPT, HCPCS Level II, and ICD-10-CM codes. If you lack billing experience or working knowledge of these subjects, AAPC offers recommended prerequisite courses to prepare you for CPB training.

How hard is the CPB exam?

Expect applied questions rather than definitions. The content spans revenue cycle fundamentals, payer rules, coordination of benefits, medical necessity, prior authorization, denial correction, appeals, payment posting, reconciliation, HIPAA, and fraud and abuse prevention. Weak spots are usually payer-specific rules and compliance details, so study those areas rather than only claim form mechanics.

What should I study first when preparing for the CPB?

Start with core billing knowledge: revenue cycle fundamentals, payer reimbursement, and clean claim requirements, since the other domains build on that vocabulary. Then move to insurance and payer requirements, followed by denials, appeals, and collections, and finish with compliance and regulatory standards. Practice applying rules to scenarios instead of memorizing lists.

What is the difference between the CPB and CPC?

AAPC explains that the CPC preparation course teaches physician office coding, including assigning diagnosis and procedure codes from operative reports and patient charts, and prepares you for the CPC exam. The CPB course emphasizes billing and only lightly touches coding, teaching how to take codes already assigned and process a claim form and work with third-party payers.

What are common reasons candidates struggle on billing exams?

Frequent trouble spots are payer-specific edits and clean claim rules, coordination of benefits order, medical necessity and prior authorization requirements, and the compliance boundaries around claim submission. Denial scenarios also trip people up when they cannot match an error to its root cause. Build accuracy by working through claim examples step by step.

How do I keep my CPB credential after passing?

AAPC states that to maintain your credential you must maintain your AAPC annual membership and earn 36 continuing education units (CEUs) every two years. Credit is not awarded for educational activities completed prior to certification, so plan your CEUs from the date you are certified.

Can I retake the CPB exam if I do not pass?

The source text provided does not describe a retake policy, including any waiting period or retake fee. Treat that detail as unconfirmed and check AAPC's exam policies directly before you schedule so you know your options and costs if you need a second attempt.
