CMS announced it will discontinue the use of certificates of medical necessity and durable medical equipment information forms after January 1, 2023. The change comes after CMS received feedback that CMNs and DIFs for selected DME were repetitive information already available on claims. The data revealed the forms especially hindered small and rural providers.
The change hopes to reduce unnecessary administrative burdens for stakeholders. It also aligns with the Biden-Harris Administration’s goals to improve access to essential, affordable care. Instead 
of adding more admin tasks, this change will allow frontline clinicians to streamline their coverage process.
Before January 1, 2023, CMS suppliers should continue to submit certificates of medical necessity and durable medical equipment information forms. After that date, medical necessity information will be found on the claim or medical record. Effective after that date, these forms will no longer be required:
- CMS-484 – Oxygen
- CMS-846 – Pneumatic Compression Devices
- CMS-847 – Osteogenesis Stimulators
- CMS-848 – Transcutaneous Electrical Nerve Stimulators
- CMS-849 – Seat Lift Mechanisms
- CMS-854 – Section C Continuation Form
- CMS-10125 – External Infusion Pumps
- CMS-10126 – Enteral and Parenteral Nutrition
