No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- 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).

Key Coverage Criteria
- 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.
- 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.
- CPT 88182 reports the physician professional and facility technical components of DNA ploidy and S-phase analysis of tumor by flow cytometry.
