CMS provider disputes
According to federal regulations that govern Medicare Advantage plans, non-contracted providers may file a payment dispute for a Medicare Advantage plan payment determination.
A payment dispute may be filed when the provider disagrees with the amount paid. This includes issues related to bundling of services.
To dispute a claim payment, submit a written request within 120 days of the remittance notification date and include, at a minimum:
- A statement indicating factual or legal basis for the dispute
- A copy of the original claim
- A copy of the remittance notice showing the claim payment
- Any additional information, clinical records or documentation to support the dispute
- Dispute form
