Common Reasons for Denial

• Oxygen equipment has exceeded number of approved paid rentals

Next Step

• If CMN is in a payable status, a telephone reopening can be conducted (CMN Required for dates of service prior to January 1, 2023).
• A Redetermination request may be submitted with all relevant supporting documentation. Review applicable Local Coverage Determination (LCD), LCD Policy Article, and documentation checklists prior to submitting request. Noridian encourages Redeterminations be submitted using the Noridian Medicare Portal.

How to Avoid Future Denials

• To verify if beneficiary has/has not had a same or similar item in the past, suppliers may call Noridian Interactive Voice Response (IVR) or use the Noridian Medicare Portal
