No Prior Auth Required

Covered without prior authorization (high confidence)

Claims must be supported by medical record documentation of the patient’s diagnosis/clinical condition and justification that the selected drug, dose, and route of administration are appropriate and medically necessary for the non-oncologic indication.
Billing must comply with Medicare rules and any applicable LCD prior authorization or documentation requirements; follow any specific forms or prior authorization processes required by the LCD or payer.
Claims must report the appropriate CPT code for the flow cytometry service, include 1 unit of service (UOS), and list the appropriate ICD-10-CM diagnosis code.
Medical necessity documentation per LCD L34513 is required when coverage criteria are not fully met in this billing guideline (for example, when >24 markers are requested).

Anti-neoplastic (chemotherapy) agent CPT/HCPCS codes may be used to bill for administration of these drugs when given to treat non-oncologic (noncancer) diagnoses if the drug is medically necessary for the patient’s condition and consistent with the standard of medical practice.
Monoclonal antibody agents and other biologic response modifiers may be administered and billed using chemotherapy administration codes for noncancer indications when the dose, route, and clinical use are appropriate and medically necessary.
Coverage and medical necessity determinations for flow cytometry are governed by Local Coverage Determination L34513.
Flow cytometry may be used to analyze cellular components of body fluids and lymphoreticular tissues, including peripheral blood, cerebrospinal fluid (CSF), bone marrow, lymph nodes, tonsil, spleen, and fine needle aspirate material.
Peripheral blood or fine needle aspirate specimens may be used to avoid more invasive diagnostic procedures when clinically appropriate.
For tests that currently lack specific CPT codes (functional intracellular analysis and total antioxidant function), bill using CPT 84999 and add a note identifying which test was performed in the Remarks area for Part A claims and the Narrative area for Part B claims.
