About 0D1K8ZK

0D1K8ZK is the ICD-10-PCS code for a bypass procedure on the ascending colon using a via natural or artificial opening endoscopic approach (qualifier: ascending colon). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to Large-to-large intestinal anastomosis, the ICD-9-CM procedure title it maps to (45.94).

For a different body part, codes include 0D188ZK (small intestine), 0D1A8ZK (jejunum), 0D1B8ZK (ileum) and 0D1H8ZK (cecum).

The same procedure with a different approach is coded 0D1K0ZK (open) and 0D1K4ZK (percutaneous endoscopic).

With a different device, use 0D1K87K (autologous tissue substitute), 0D1K8JK (synthetic substitute) and 0D1K8KK (nonautologous tissue substitute).

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), DRG 331 (Major Small and Large Bowel Procedures without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Major Small and Large Bowel Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures” and “Other O.R. Procedures for Injuries”.

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