There are 3 ways to file a complaint about DME:
Contact your supplier
- Within 5 calendar days, your supplier must let you know they got your complaint and are investigating it.
- Within 14 calendar days, your supplier must send you the result of your complaint and their response in writing.
Ask to send your complaint to the Competitive Acquisition Ombudsman (CAO)
If you still need help after contacting your supplier or 1-800-MEDICARE, ask the 1-800-MEDICARE representative to send your complaint to the CAO. The CAO responds to individual and supplier inquiries, issues, and complaints, and helps make sure that your complaint is resolved.
