The CPB (Certified Professional Biller) is the AAPC's credential for medical billing professionals. It validates your knowledge of the full billing process: insurance types and payer rules, billing regulations, claim submission, reimbursement, collections and appeals. CPB holders help practices and facilities get paid correctly and on time while staying compliant with Medicare, Medicaid and commercial payer requirements.
The CPB exam evaluates your knowledge across these areas:
Medicare, Medicare Advantage, Medicaid, TRICARE and commercial plans.
Global surgery, teaching physician rules, ACOs and the False Claims Act.
CMS-1500 and UB-04 claims, ABNs, modifiers and the appeals process.
Fee schedules, assignment, remittance advice and collections.

Prepares and submits claims, posts payments, follows up on denials, handles appeals and collections, and makes sure billing follows payer and federal rules.
Learn the rules for each payer type, practice CMS-1500 and UB-04 scenarios, review the appeal levels and ABN rules, then take timed practice exams. Our five CPB practice sets follow these areas.
The CPB shows you can manage the billing side of healthcare with confidence. It supports careers in physician practice billing, hospital patient accounts and revenue cycle teams.
