What A9530 covers
A9530 identifies therapeutic iodine-131 sodium iodide in liquid form for oral administration. Nuclear medicine services commonly use this radioiodine treatment for hyperthyroidism or differentiated thyroid cancer. A nuclear medicine physician or another clinician overseeing radioiodine treatment may administer it in a hospital or other authorized treatment setting; the radiopharmaceutical may be supplied through a radiopharmacy.
The HCPCS unit is one millicurie, so report the number of units that corresponds to the amount supplied or administered. A9530 is for therapeutic solution, not a diagnostic iodine-131 preparation or the therapeutic capsule formulation. Medicare assigns physician fee schedule status C: there is no national physician fee schedule payment, and the Medicare Administrative Contractor sets payment for the claim under contractor pricing. Coverage is left to the contractor’s judgment.
