About 0D773ZZ

0D773ZZ is the ICD-10-PCS code for a dilation procedure on the stomach, pylorus using a percutaneous approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to dilation of pylorus by incision, the ICD-9-CM procedure title it maps to (44.21).

For a different body part, codes include 0D713ZZ (esophagus, upper), 0D723ZZ (esophagus, middle), 0D733ZZ (esophagus, lower), 0D743ZZ (esophagogastric junction), 0D753ZZ (esophagus), 0D763ZZ (stomach) and 15 more.

The same procedure with a different approach is coded 0D770ZZ (open), 0D774ZZ (percutaneous endoscopic), 0D777ZZ (via natural or artificial opening) and 0D778ZZ (via natural or artificial opening endoscopic).

With a different device, use 0D773DZ (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for DRG 326 (Stomach, Esophageal and Duodenal Procedures with MCC), DRG 327 (Stomach, Esophageal and Duodenal Procedures with CC) and DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), under the surgical category “Stomach, Esophageal and Duodenal Procedures”.

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