CMS (Medicare) has determined that Thyroid Testing (CPT Codes 84436, 84439, 84443, 84479) is only medically necessary and, therefore, reimbursable by Medicare when ordered for patients with any of the diagnostic conditions listed below in the “ICD-9-CM Codes Covered by Medicare Program.” If you are ordering this test for a diagnostic condition other than those listed below, please have your patient sign and date an Advanced Beneficiary Notice (ABN). All ICD-9-CM codes provided must be consistent with the documentation in the patient’s medical records for the date of service.
