Medical necessity for each test must be documented in the patient's medical record as required by LCD L35006.
All documentation must be maintained in the patient's medical record and made available to the contractor upon request; every page must be legible and include patient identification and dates of service.
Documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care to the patient.
The submitted medical record must support the selected ICD-10-CM code(s) and the submitted CPT/HCPCS code must accurately describe the service performed.

Urine drug testing (UDT) and drugs-of-abuse testing are covered when reasonable and necessary per LCD L35006 and ordered on an individual patient basis by the treating clinician with medical-record documentation of medical necessity.
Patients with a documented diagnosis consistent with substance use disorder (SUD) may qualify for an exception to the standard presumptive UDT annual limits.
RAST type tests are covered when medically necessary and supported by the related Local Coverage Determination (LCD) and current medical literature or standards of practice.
Monitored Anesthesia Care (MAC) is medically necessary when the patient has one or more documented diagnoses listed as supporting medical necessity (e.g., F91.9, G97.81, T81.9XXA, T88.8XXA, F79) and the diagnosis is matched to the anesthesia/CPT/HCPCS procedure performed.
Use G9 anesthesia modifier to indicate need for MAC due to a history of severe or advanced cardiopulmonary disease when the proceduralist determines additional monitoring is required.
Use G8 anesthesia modifier for certain deep, complex, complicated, or markedly invasive surgical procedures when applied to anesthesia codes 00100, 00300, 00400, 00160, 00532, or 00920.
