Flow Cytometry

Flow cytometry is covered for diagnosis, classification, prognostic assessment, therapeutic-target antigen detection, and residual disease monitoring in hematopoietic neoplasms, for monitoring lymphocyte populations in HIV and post-transplant patients, for disease-specific antigen identification (e.g., CD59 in PNH), and for CD34 counts for stem cell transplant. Coverage requires appropriate documentation by the pathologist and communication of results to the treating clinician; services that are statutorily excluded, have no Medicare benefit category, or are for screening are not covered. Administrative billing rules (Part A vs Part B, FQHC bill type 77X) and advance written notice to beneficiaries when tests may not be covered also apply.
