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.
Coverage and reasonable/necessary determinations for assays for vitamins and metabolic function are governed by LCD L34914 and claims must meet that LCD's requirements to be covered.
