DME Authorization
DME denials leave patients without critical equipment.
Prepare a case the medical director can't refuse.
Durable Medical Equipment (DME) prior authorization is one of the most frustrating areas of utilization management for physicians and their staff. From CPAP machines to power wheelchairs, hospital beds to prosthetics -- DME denials are rampant, and the appeal process is byzantine. The P2P call is often your best shot at overturning these denials.
Why DME Denials Are So Common
DME has some of the strictest coverage criteria in healthcare. Medicare and commercial payers require specific clinical documentation thresholds: sleep study results within certain parameters for CPAP, specific mobility assessments for wheelchairs, documented home safety evaluations for hospital beds, and detailed fitting requirements for prosthetics. Most denials happen because the ordering physician's documentation doesn't check every box on the payer's coverage determination checklist -- even when the medical need is obvious.
The DME Coverage Determination Process
Each DME category has its own Local Coverage Determination (LCD) or National Coverage Determination (NCD) that specifies exactly what clinical criteria must be documented. For Medicare, these are published by the DME MAC (Medicare Administrative Contractor) for your region. Commercial payers generally follow similar criteria but may have additional requirements. Before your P2P call, identify the exact LCD/NCD that applies to your DME order and compare your documentation point by point.
Winning DME P2P Calls
DME P2P calls require a different approach than inpatient reviews. The medical director will have the LCD/NCD criteria in front of them. Your job is to walk through each criterion and show how your patient meets it. Be specific: if the criteria requires a 'qualifying sleep study,' cite the exact AHI number. If it requires 'failure of conservative therapy,' document exactly what was tried and for how long. If there's a functional limitation requirement, describe the specific ADL impacts with examples.
Common DME Categories and Strategies
CPAP/BiPAP: Have the sleep study results ready with AHI/RDI scores, documented compliance attempts, and face-to-face evaluation notes. Power Wheelchairs: Prepare the mobility examination, document the specific mobility limitations, and have the ATP evaluation ready. Hospital Beds: Document the specific medical condition requiring the bed, positioning needs, and why a standard bed is insufficient. Prosthetics: Have the K-level assessment, rehabilitation potential documentation, and functional goals clearly stated.
Common denial reasons
1.Documentation does not meet LCD/NCD coverage criteria
2.Sleep study results do not meet threshold requirements
3.Insufficient documentation of medical necessity
4.Missing face-to-face encounter documentation
5.Mobility examination does not support power mobility device
6.Conservative treatment not adequately documented
7.Prior authorization not obtained before delivery
P2P call tips
Pull the exact LCD/NCD and walk through criteria point by point
Have the specific clinical values ready (AHI scores, FVC results, etc.)
Document functional limitations using specific ADL examples
Reference the face-to-face encounter date and findings
If Medicare, know your DME MAC's specific policies
Ask the reviewer which specific criterion was not met
