Question: South Carolina Subscriber Answer: Then, use J3300 (Injection, triamcinolone acetonide, preservative free, 1 mg) or J3301 (Injection, triamcinolone acetonide, not otherwise specified, 10 mg) for the Kenalog itself. Pay careful attention to the code descriptors when reporting units. For J3300, you should report 1 unit per 1 mg. In contrast, you should report 1 unit per 10 mg for J3301. Physicians may order injections of this corticosteroid for patients with certain hematologic disorders (acquired hemolytic anemia, Diamond-Blackfan anemia, pure red cell aplasia, and certain cases of secondary thrombocytopenia), as well as a variety of other conditions, including hypercalcemia associated with cancer.
