Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 79300 covers

This CPT service describes treatment using a radioactive colloid placed within tissue at a targeted site. Interstitial administration means placement into tissue, rather than delivery into a body cavity, joint, or bloodstream. Nuclear medicine and radiation oncology teams may provide or report the service in settings equipped to administer therapeutic radiopharmaceuticals; the route and material distinguish it from other radiopharmaceutical therapy codes.

Medicare assigns this code physician fee schedule status C, or carrier priced: there is no national payment amount, and the Medicare Administrative Contractor sets payment for each claim. The professional interpretation may be reported with modifier 26, and the technical portion for equipment and staff with modifier TC; billing without either modifier represents the global service. Select the component that matches the service furnished and documented.

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.
