Hello coders, my surgeon bills a tenosynovectomy often when doing carpal tunnel release. He uses a diagnosis of tenosynovitis and uses 26145. He says the tenosynovectomy is at the level of palm. With caresource insurance the 727.05 is not an acceptable diagnosis. Are these two surgeries not billable together, or is there a better cpt code? Anyone billing these two procedures together? Is there documentation anywhere to help with this? Thanks, Paula
