Multiple Wart Injections

Question: If the dermatologist injects two warts five times each, would I need to report 10 units of 11900?

California Subscriber

Answer: CPT® code 11900 (Injection, intralesional; up to and including 7 lesions) specifies the number of lesions treated — in this case, up to and including seven. Your dermatologist only treated two warts, so only one unit of 11900 describes the physician’s work.
