CPB Certification (AAPC): The Medical Billing Credential Explained (2026)

Key takeaway: The Certified Professional Biller is AAPC’s credential for the billing side of the revenue cycle: payer rules, claim submission, denials, appeals, and collections. It suits people who want billing or revenue cycle roles rather than coding, and it pairs with the CPC for those who do both.

If denials, payer portals, and getting a claim paid sound more like you than surgical CPT, start here. Many “biller” postings still list the CPC because small practices want one person who can do both. Read the ads. This site is not affiliated with AAPC.

What the CPB covers

As published by AAPC:

• Insurance types and payer rules, including Medicare and Medicaid basics
• Billing regulations and compliance, including HIPAA
• The claim cycle from eligibility through appeals and patient collections
• Reimbursement methods and remittance interpretation
• Coding fundamentals sufficient to review a claim
• Case analysis questions that mirror real billing scenarios

Eligibility and renewal

AAPC does not require a course, recommends relevant education, and requires membership. Like other AAPC credentials it renews every two years through continuing education units.

You can sit this exam without being a CPC. You cannot skip knowing enough CPT and ICD-10-CM to see why a line denied.

The CPB does not skip coding or an on-site first job

The CPB will not make you a coder, and it will not skip the on-site first job. Billing companies hire new people; they also measure days in A/R. If you hate follow-up, this credential will not change the work.
