Medicare Medical Necessity
As an informational service to Labcorp accounts, this page contains certain Local Coverage Determinations (LCDs) issued by the Medicare Administrative Contractors (MACs) and National Coverage Determinations (NCDs) issued by the Centers for Medicare & Medicaid Services (CMS).
A claim submitted for payment of a test on a local or national list—without a specific diagnosis code that indicates medical necessity based upon the local or national policies—will result in denial of payment for these services. The Medicare program will allow the laboratory to bill the patient for denied LCD/NCD coverage services only if an Advance Beneficiary Notice of Non-coverage (ABN) is completed, signed and dated by the patient prior to service being rendered, and forwarded to the laboratory prior to testing. This policy applies to all Medicare Part B providers of clinical laboratory services. Diagnosis codes provided must be reflected in the patient's medical record.

There can be no representation or warranty as to the accuracy or completeness of the information or that use of this information will comply with the local or national policies. To ensure the accurate and appropriate use of the information, it is recommended that the Medicare Administrative Contractor be consulted. Primary sources (ie, Medicare Administrative Contractor publications, notices, and advice) should be consulted prior to the use of this information for purposes other than for submitting diagnosis codes to Labcorp. This is particularly important since information is often affected by ongoing developments.
NOTE: PRINTING THE MEDICAL NECESSITY INFORMATION
While every effort is made to provide information that is up-to-date, policy updates take place frequently and, as a result, retaining/using a printed version may not represent the most current information. Please also note that the LCD/NCD policy information is more than 700 pages in length.
