About 0DLK7ZZ

0DLK7ZZ is the ICD-10-PCS code for a occlusion procedure on the ascending colon using a via natural or artificial opening approach. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other operations on intestines, the ICD-9-CM procedure title it maps to (46.99).

For a different body part, codes include 0DL17ZZ (esophagus, upper), 0DL27ZZ (esophagus, middle), 0DL37ZZ (esophagus, lower), 0DL47ZZ (esophagogastric junction), 0DL57ZZ (esophagus), 0DL67ZZ (stomach) and 15 more.

The same procedure with a different approach is coded 0DLK0ZZ (open), 0DLK3ZZ (percutaneous), 0DLK4ZZ (percutaneous endoscopic) and 0DLK8ZZ (via natural or artificial opening endoscopic).

With a different device, use 0DLK7DZ (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for DRG 329 (Major Small and Large Bowel Procedures with MCC), DRG 330 (Major Small and Large Bowel Procedures with CC) and DRG 331 (Major Small and Large Bowel Procedures without CC/MCC), under the surgical category “Major Small and Large Bowel Procedures”.

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