Medical Necessity - Medicare

The Centers for Medicare and Medicaid Services (CMS) is responsible for ensuring that services being paid for by the Medicare program are medically necessary. CMS has created national edits called National Coverage Determinations (NCDs), which require documentation of medical necessity before a claim may be paid. In addition, local carriers maintain a list of Local Medical Review Policies (LMRPs) that also require documentation of medical necessity.

Local Medicare carriers have the authority to deny claims when the diagnosis code(s) provided for a test does not substantiate medical necessity. If a physician does not submit a covered ICD-9 code for an NCD or LMRP, AMS will contact the physician’s office to request a diagnosis indicating medical necessity. If a covered diagnosis code is not available, AMS will expect a completed Advanced Beneficiary Notice to be attached to the requisition in order to bill the patient. Directions for completing the ABN are on the requisition. If an ABN has not been completed, AMS will bill the client.

Tests that are subject to NCDs and LMRPs are printed in red on the requsitions. The Medicare carrier may approve additional LMRPs for other laboratory tests at any time. A complete listing of all NCDs and LMRPs along with covered diagnosis codes can be found at
