About 0D19079

0D19079 is the ICD-10-PCS code for a bypass procedure on the duodenum using an open approach with autologous tissue substitute (qualifier: duodenum). 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 0D11079 (esophagus, upper), 0D12079 (esophagus, middle), 0D13079 (esophagus, lower), 0D15079 (esophagus) and 0D16079 (stomach).

The same procedure with a different approach is coded 0D19479 (percutaneous endoscopic) and 0D19879 (via natural or artificial opening endoscopic).

With a different device, use 0D190J9 (synthetic substitute), 0D190K9 (nonautologous tissue substitute) and 0D190Z9 (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.
