The Certified Professional Biller (CPB) credential demonstrates skills related to maintaining all aspects of the revenue cycle, particularly patient and payer billing and collections. Without expertise in medical billing and the nuances of payer requirements, healthcare provider reimbursement may be compromised.

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.
