What is Provider Enrollment?

Provider enrollment is a critical function for ensuring that only qualified individuals and entities meeting CMS eligibility criteria are enrolled in the Medicare program and receive reimbursement for services furnished to Medicare beneficiaries.

Physicians, non-physician practitioners, suppliers, and other qualified providers must first enroll in the program in order to submit claims and receive payment for Medicare covered services.

WPS Medicare is responsible for Medicare Part B provider enrollment for Iowa, Kansas, Missouri, and Nebraska.
