Physician Signature Requirements for Diagnostic Tests

A physician’s signature is not required on orders for clinical diagnostic tests (including X-ray, laboratory and other diagnostic tests) that are paid on the basis of the clinical laboratory fee schedule or the Medicare Physician Fee Schedule, or for physician pathology services. While a physician order is not required to be signed, the physician must clearly document in the medical record his intent that the test be performed.
