Request Submission Tips
- Include proper and legible documentation - Include legible medical records, prescriptions, refill requests, proof of delivery, Certificates of Medical Necessity (CMNs), DME Information Forms (DIFs), and/or the Advance Beneficiary Notice of Noncoverage (ABN) as appropriate. Do not include a corrected claim
- If medical notes are handwritten and/or illegible, the appeal will remain denied as there is no medical documentation to review. If any illegible documentation is submitted, it will be excluded as only legible pieces are considered as part of appeal request
- Include valid appellant signatures - Requests received without appellant's signature are dismissed as incomplete requests
- To appeal overpayment, check "Yes" in Overpayment Appeal section of "Medicare DME Redetermination Request Form" or "Does this appeal involve and overpayment?" box in CMS-20027 "Medicare DME Redetermination Request Form"
- Include a copy of overpayment letter
- Send request to specific Post Office Box for "Overpayment Redetermination and Rebuttal Requests"
- Submit Extrapolation Redetermination requests. View Extrapolation webpage for more information
- 120 days of initial claim determination date (date on Medicare Remittance Advice (RA) or beneficiary's Medicare Summary Notice (MSN))
- A request filed is considered to be filed the date the MAC receives it. The time limit for a request is computed by allowing five additional days beyond the time limit from the RA or MSN date. This allows a 5-day period for mail delivery
- When filing deadline ends on a Saturday, Sunday, legal holiday, or any other nonwork day, the contractor shall apply a rollover period that extends filing deadline to first working day after the Saturday, Sunday, legal holiday, or other nonwork day. Example: Filing deadline falls on Saturday before Columbus Day, filing deadline is then extended to first working day after Columbus Day holiday
- Requests made after the 120-day time limit must include an explanation regarding the late file
- Good cause may apply for a late filing, see CMS Internet Only Manual (IOM), Publication 100-04, Medicare Claims Processing Manual, Publication, Chapter 29 as it addresses the issue of good cause for extension of the time limit for filing appeals. If good cause is not found, request will be dismissed
