We are an ASC and billing for a 46930-Destruction of internal hemorrhoid(s) by thermal energy (eg, infrared coagulation, cautery, radiofrequency) and a 45330-Sigmoidoscopy, flexible; diagnostic, with or without collection of specimen(s) by brushing or washing (separate procedure) . Patient had both procedures on same day/same time. Would a modifier be required on this? I did not see that there was one required based on the CCI edits. Thanks.
