What 79101 covers
Code 79101 represents therapeutic delivery of a radiopharmaceutical through a vein. It is used when treatment requires intravenous administration rather than oral dosing or another delivery route. Nuclear medicine physicians and other qualified clinicians may provide the service in a hospital or outpatient nuclear medicine setting, with the radiopharmaceutical prepared and administered under appropriate clinical supervision. The treatment record should identify the agent, the therapeutic purpose, the intravenous route, and the administration performed.
Choose this code by the route of administration, not by the imaging used to assess the condition. Document the administered agent and activity, treatment date, and relevant administration details so the service can be distinguished from oral or nonintravenous therapy. CMS identifies separately priced professional and technical components: report modifier 26 for the professional interpretation and modifier TC for the technical portion involving equipment and staff. Report without either modifier for the global service.

How to choose
79101 billing questions
How do I distinguish 79101 from oral radiopharmaceutical therapy?
Use 79101 when the therapeutic radiopharmaceutical is administered intravenously. Oral administration is represented by a different route-specific code.
Which modifiers identify the components?
Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion involving equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports 79101?
The record should identify the therapeutic agent, treatment purpose, intravenous route, administered activity, and date and details of administration.
Is 79101 selected by the drug or by the route?
Select it based on intravenous administration. The route distinguishes it from oral, intra-arterial, intracavitary, and other radiopharmaceutical therapy codes.
Does reporting 79101 without a modifier include both components?
Yes. CMS identifies an unmodified claim as the global service; modifiers 26 and TC separately identify the professional and technical portions.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
