Answer: The otolaryngologist in your case injects the corticosteroid into a lesion (a hemangioma is a common benign growth developed from blood vessels). You should report the intralesional injection with 11900 (Injection, intralesional; up to and including seven lesions).
When a physician injects a steroid into the skin or muscle, you should instead use 90772 (Therapeutic, prophylactic or diagnostic injection [specify substance or drug]; subcutaneous or intramuscular).
In an office, you should also bill for physician-supplied medicine with J3301 (Injection, triamcinolone acetonide, per 10 mg).
