The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care to the patient.

  4. The medical record documentation must support the medical necessity of the services as directed in this policy.
  5. The laboratory or billing provider must have on file the physician requisition which sets forth the diagnosis or condition (ICD-10-CM code) that warrants the test(s).

  8. Medical record documentation must clearly indicate the rationale which supports the medical necessity for performing eGFR by measurement of cystatin C (i.e. support GFR estimates based on serum creatinine are thought to be inaccurate and what decisions depend on more accurate knowledge of the GFR) and must reflect how the test result were used in the patient’s plan of care.
