Which item is not typically required for prior authorization of a high-cost DME item?

• A. Physician order
• B. Diagnosis
• C. Treatment rationale
• D. Device warranty terms

Answer: (D)

Prior authorization for a high-cost DME item centers on proving medical necessity and meeting coverage criteria. The payer typically needs a physician order to confirm who is prescribing the device, a diagnosis that links the device to a specific medical condition, and a treatment rationale that explains why this device is appropriate and why alternatives wouldn't meet the patient’s needs. These elements establish that the device will meaningfully improve health or function and are the main drivers of the authorization decision.

Device warranty terms, while important for vendor guarantees and post-approval service, do not influence the payer’s determination of medical necessity or coverage. They describe durability, replacement terms, and service obligations rather than the clinical reason for needing the device. So they are not typically required in the prior authorization submission.
