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).
This billing/coding guideline complements LCD L33459 (Computerized Axial Tomography (CT), Thorax); follow the LCD for clinical coverage and any required documentation or prior authorization rules.
The ordering/referring practitioner's assessment related to the patient's complaint and the specific reason for the test must be documented in the medical record.

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.
Non-invasive vascular diagnostic tests are covered when ordered by the treating practitioner or a consulting physician who will use the results to manage the beneficiary's specific medical problem.
A documented referral/order must be on record for each individual non-invasive vascular study performed for coverage to apply.
Cerebrovascular arterial duplex follow-up is covered annually for stenosis 20–49% (diameter reduction).
