Submission of Refund Checks to Fidelis Care
3/3/2026 • Posted by Provider Relations in Provider News

Fidelis Care is committed to ensuring accurate claims processing and compliance with state and federal requirements. Providers who identify an overpayment may self‑disclose and refund the amount owed by submitting a refund check along with the required documentation.

When a Refund Is Required

If your office identifies an overpayment—whether through internal review, reconciliation, or audit—you may self‑disclose by submitting:

  • A refund check, and
  • A completed Provider Claim Refund Form (located on page 91 in the Provider Manual)

Submitting refunds promptly helps ensure accurate member records and supports ongoing compliance.
