About 79440: Intra-articular radiopharmaceutical therapy
Reports radiopharmaceutical treatment delivered into a joint to treat synovial disease, such as persistent inflammatory synovitis or synovitis associated with hemophilic arthropathy.
This service delivers a therapeutic radiopharmaceutical directly into a joint to treat synovial disease, rather than using a routine medication injection. It is generally performed by a nuclear medicine or radiology physician with the joint accessed by a qualified clinician, often in a specialized outpatient or hospital setting. Examples include treatment of persistent synovitis associated with inflammatory arthritis or hemophilic arthropathy.
Select 79440 when documentation supports intra-articular delivery of a radiopharmaceutical for therapy. The record should identify the treated joint, the therapeutic purpose, and the administration performed. CMS recognizes professional and technical components: modifier 26 reports the professional interpretation, modifier TC reports the technical component, and billing without either modifier represents the global service. The technical component includes equipment and staff.

79440 billing questions
When should 79440 be chosen over 79445?
Use 79440 for radiopharmaceutical treatment delivered into a joint. Code 79445 describes treatment delivered by the intra-arterial route.
Does 79440 describe ordinary medication injection into a joint?
No. It is for intra-articular radiopharmaceutical therapy, such as treatment directed at diseased synovium, rather than a routine corticosteroid or anesthetic injection.
How are the professional and technical components reported?
Report modifier 26 for the professional interpretation or modifier TC for the technical component. Without either modifier, the claim represents the global service.
What documentation supports reporting 79440?
Document the joint treated, the therapeutic indication, and that a radiopharmaceutical was administered intra-articularly. The record should distinguish this treatment from an ordinary joint injection.
Does 79440 identify the specific joint or number of joints treated?
The code identifies the intra-articular radiopharmaceutical therapy, not a particular joint. Document each treated site and the service performed; do not infer a unit count from the code descriptor alone.
