About 0DSM4ZZ

0DSM4ZZ is the ICD-10-PCS code for a reposition procedure on the descending colon using a percutaneous endoscopic approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to other fixation of large intestine, the ICD-9-CM procedure title it maps to (46.64).

For a different body part, codes include 0DS54ZZ (esophagus), 0DS64ZZ (stomach), 0DS84ZZ (small intestine), 0DS94ZZ (duodenum), 0DSA4ZZ (jejunum), 0DSB4ZZ (ileum) and 7 more.

The same procedure with a different approach is coded 0DSM0ZZ (open), 0DSM7ZZ (via natural or artificial opening), 0DSM8ZZ (via natural or artificial opening endoscopic) and 0DSMXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 344 (Minor Small and Large Bowel Procedures with MCC), DRG 345 (Minor Small and Large Bowel Procedures with CC) and DRG 346 (Minor Small and Large Bowel Procedures without CC/MCC), under the surgical category “Minor Small and Large Bowel Procedures”.

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