About 0WJP8ZZ

0WJP8ZZ is the ICD-10-PCS code for a inspection procedure on the gastrointestinal tract using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other nonoperative measurements and examinations, the ICD-9-CM procedure title it maps to (89.39).

For a different body part, codes include 0WJQ8ZZ (respiratory tract) and 0WJR8ZZ (genitourinary tract).

The same procedure with a different approach is coded 0WJP0ZZ (open), 0WJP3ZZ (percutaneous), 0WJP4ZZ (percutaneous endoscopic) and 0WJP7ZZ (via natural or artificial opening).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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