About 0D9R00Z

0D9R00Z is the ICD-10-PCS code for a drainage procedure on the anal sphincter using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other anal sphincterotomy, the ICD-9-CM procedure title it maps to (49.59).

For a different body part, codes include 0D9100Z (esophagus, upper), 0D9200Z (esophagus, middle), 0D9300Z (esophagus, lower), 0D9400Z (esophagogastric junction), 0D9500Z (esophagus), 0D9600Z (stomach) and 20 more.

The same procedure with a different approach is coded 0D9R30Z (percutaneous) and 0D9R40Z (percutaneous endoscopic).

With a different device, use 0D9R0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 347 (Anal and Stomal Procedures with MCC), DRG 348 (Anal and Stomal Procedures with CC) and DRG 349 (Anal and Stomal Procedures without CC/MCC), under the surgical category “Anal and Stomal Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
