Welcome to the WPS Medicare Appeals web page.

The Medicare program offers to physicians, suppliers, and beneficiaries the right to appeal claim determinations made by the carrier. The purpose of the appeals process is to ensure the correct adjudication of claims. The appeals activities conducted by carriers are governed by instructions from the Centers for Medicare & Medicaid Services (CMS).

Redetermination - First level of appeal. An appeal of a claim is performed when a claim denied or reduced and no clerical error was made. The request for appeal must clearly state why you are in disagreement with the reduction or denial decision that was made on the initial claim.
Clerical Error Reopening - A reopening is performed to make a minor change or correction to a previously processed claim. For example, you omitted or incorrectly keyed the diagnosis code or a modifier which resulted in a claim denial.
The Centers for Medicare & Medicaid Services (CMS) provide the instructions for reopening activities conducted by MACs. Section 937 of the Medicare Modernization Act (MMA) required CMS to establish a process whereby providers, physicians, and suppliers could correct minor error or omissions outside of the appeals process.
