About 0D1B4KB

0D1B4KB is the ICD-10-PCS code for a bypass procedure on the ileum using a percutaneous endoscopic approach with nonautologous tissue substitute (qualifier: ileum). 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 Small-to-small intestinal anastomosis, the ICD-9-CM procedure title it maps to (45.91).

For a different body part, codes include 0D114KB (esophagus, upper), 0D124KB (esophagus, middle), 0D134KB (esophagus, lower), 0D154KB (esophagus), 0D164KB (stomach), 0D194KB (duodenum) and 1 more.

The same procedure with a different approach is coded 0D1B0KB (open) and 0D1B8KB (via natural or artificial opening endoscopic).

With a different device, use 0D1B47B (autologous tissue substitute), 0D1B4JB (synthetic substitute) and 0D1B4ZB (no 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), DRG 331 (Major Small and Large Bowel Procedures without CC/MCC), DRG 619 (O.R. Procedures for Obesity with MCC), DRG 620 (O.R. Procedures for Obesity with CC) and DRG 621 (O.R. Procedures for Obesity without CC/MCC), under the surgical categories “Major Small and Large Bowel Procedures”, “O.R. Procedures for Obesity”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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