Final answer:
The initial step in the Medicare appeal process is a Redetermination, and beneficiaries or providers must file it within 120 days of receiving the initial claim determination.
Step-by-step explanation:
The first level of the Medicare appeal process is called a Redetermination. Upon receiving the initial claim determination, a beneficiary or provider has 120 days to request a Redetermination from the same Medicare Administrative Contractor (MAC) that made the initial determination. The Redetermination is the first step where the MAC reviews its original decision, providing an opportunity for the claim to be re-evaluated.
The first level of Medicare's appeal process is called the redetermination. After receiving the initial claim determination, you have 120 days to file for redetermination. During this level, the appeal is reviewed by a different Medicare contractor who was not involved in the initial decision-making process. It is important to provide any additional supporting documentation or evidence that may strengthen your case.
