CPB Medical Billing study guide
CPB Medical Billing · Work through your exam, one topic at a time.
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). The CPB Medical Billing study guide has 4 sections and about 1,565 words.
