Medical Necessity

The Health Care Financing Administration (HCFA) is responsible for administering the Medicare Program throughout the United States. Medicare does not cover routine screening tests and will only pay for tests that meet Medicare coverage criteria. Medicare will only pay for those tests which it considers reasonable and necessary, and supported by the patient’s medical record. To document medical necessity of the ordered tests, physicians must provide ICD-9 codes specific to the patient’s condition on the specific date of service.

Advanced Beneficiary Notices

If reimbursement is denied for improper documentation of medical necessity, Medicare prohibits the laboratory from billing the patient unless an Advanced Beneficiary Notice (ABN) has been signed and dated by the patient PRIOR to the provision of service. The ABN insures the patient is informed of Medicare’s medical necessity policy, reviews why payment may be denied on the specific tests being ordered, and requires both the patient’s and physician’s signature. A copy of the Westchester Medical Center Advanced Laboratory Services ABN may be found on the back of the laboratory test requisition, and is required for Medicare patients anytime a test highlighted is ordered. The ABN should be signed and dated after the requisition has been completed. To insure complete compliance on both the laboratory’s and the physician’s part, the physician must enter the appropriate ICD-9 codes to document the medical necessity of the tests being ordered.
