Coding Communication:Colonoscopy Coding Made Simple from CPT Assistant
The public awareness of colorectal cancer screening and surveillance has increased dramatically over the past several years. Colonoscopy is the most effective diagnostic procedure for colon polyps and early colorectal cancer. While this procedure is performed more than 2 million times each year, questions about colonoscopy coding for biopsy and removal of colorectal polyps continue. Proper determination is achieved by carefully considering the code descriptors and similarities that exist as well as the intended use of the codes and the potential problems.
Codes in Question
45378Colonoscopy, flexible, proximal to the splenic flexure; diagnostic, with or without collection of specimen(s) by brushing or washing, with or without colon decompression
45380with biopsy, single or multiple
45381with directed submucosal injection(s), any substance
45383with ablation of tumor(s), polyp(s), or other lesion(s) not amenable to removal by hot biopsy forceps, bipolar cautery or snare technique
45384with removal of tumor(s), polyp(s), or other lesion(s) by hot biopsy forceps or bipolar cautery
45385with removal of tumor(s), polyp(s), or other lesion(s) by snare technique
Medicare uses unique procedural codes to identify claims for services when colonoscopy is performed strictly for colorectal neoplasia screening in patients with average risk (G0121, Colorectal cancer screening; colonoscopy on individual not meeting criteria for high risk) and high risk (G0105, Colorectal cancer screening; colonoscopy on individual at high risk) for colon cancer. In these cases, the unique Medicare code is reported instead of the standard CPT colonoscopy code (45378) when there is no need for a therapeutic procedure. Therapeutic procedures include simple biopsies, snare polypectomy, etc. If a therapeutic procedure is performed, then the appropriate CPT code(s) are reported with the ICD-9-CM
diagnosis code that reflects the finding that required the therapeutic procedure. The diagnosis code reflecting the indication should be listed secondarily. If there is no need for a therapeutic procedure, the Medicare G-code is listed with an ICD-9-CM code reflecting the indication. The ICD-9-CM code for screening colonoscopy examinations in average risk patients is V76.51. There are several acceptable ICD-9-CM codes for screening colonoscopy in high risk patients. Incidental findings (eg, diverticulosis, hemorrhoids) not requiring therapeutic procedures can be identified as an additional ICD-9-CM code(s) after the ICD-9-CM code reflecting the indication for the procedure.
Hope this helps!!!
