The AAPC CPB exam consists of 100 multiple-choice questions with a 4-hour time limit. A score of 70% or higher is required to pass. The exam is delivered electronically via live remote proctoring or at a testing center. AAPC membership is required.

How should I study for CPB in 2026?

What is the difference between CPB and CPC?

CPB (Certified Professional Biller) focuses on the business side of healthcare — billing, claims, revenue cycle, payer rules, and compliance. CPC (Certified Professional Coder) focuses on the clinical coding side — CPT, ICD-10-CM, and HCPCS code assignment from documentation. Many professionals hold both credentials.

Is CPC required before taking CPB?

No. CPC and CPB are independent certifications. You can take CPB without having CPC. However, some CPB exam content involves coding fundamentals, so basic familiarity with ICD-10-CM and CPT is helpful.

What career opportunities does CPB open?

CPB-certified professionals work in medical billing departments, revenue cycle management, insurance follow-up, denial management, payment posting, patient financial services, and billing management roles across physician practices, hospitals, and billing companies.

Can I take the CPB exam remotely?

Yes. AAPC offers the CPB exam via live remote proctoring (LRP) through Meazure Learning/ProctorU, in addition to testing center delivery. You need a computer with webcam, microphone, and stable internet connection.
