PECOS, the Provider Enrollment, Chain, and Ownership System, is the CMS web-based portal through which healthcare providers and suppliers enroll in Medicare, update their enrollment information, and manage their participation status.

In-house credentialing costs a medical practice $75,000 to $100,000 per year once salary, benefits, payroll taxes, software, and management oversight are fully accounted for.

That’s also per provider, per payer […]
