Certified Professional Biller (CPB) - Certification Exam


The Certified Professional Biller (CPB) credential prepares medical billers with skills to maintain all aspects of the revenue cycle. Without expertise in medical billing and the nuances of payer requirements, healthcare provider reimbursement may be compromised.

Validate Your Expertise

Through rigorous examination and experience, CPBs have proven knowledge of how to submit claims compliant with government regulations and private payer policies. They follow up on claim statuses, resolve claim denials, submit appeals, post payments and adjustments, and manage collections. The CPB medical billing credential is vital to the financial success of the professional healthcare services claims process.

CPBs Earn Their Worth

According to AAPC's 2022 Salary Survey, medical billers with CPB certification average $55,078 in annual salary. If you want to see how much earning potential you have with medical billing expertise, can calculate the average CPB salary in your area, based on your job responsibility. Keep in mind that a CPB's annual salary varies based on the size of the practice you bill for or whether you work in a large facility. Other factors include years of experience, how many credentials held, and your location.

CPBs have demonstrated:

  • An understanding of various types of insurance plans
  • Expertise in applying payer policy, Local Coverage Determinations (LCDs), and National Coverage Determinations (NCDs) for successful claim submissions
  • Knowledge of CPT®, ICD-10-CM, and HCPCS Level II coding guidelines
  • Successful navigation of healthcare industry rules and regulations, including HIPAA, False Claims Act, Fair Debt Collections Act, and Stark Law.
  • An understanding of the life cycle of a medical billing claim and how to improve the revenue cycle
  • Expertise in effective claim follow-up, patient follow-up, and denial resolution
