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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
