About 0D9J4ZX

0D9J4ZX is the ICD-10-PCS code for a drainage procedure on the appendix using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other operations on appendix, the ICD-9-CM procedure title it maps to (47.99).

For a different body part, codes include 0D914ZX (esophagus, upper), 0D924ZX (esophagus, middle), 0D934ZX (esophagus, lower), 0D944ZX (esophagogastric junction), 0D954ZX (esophagus), 0D964ZX (stomach) and 20 more.

The same procedure with a different approach is coded 0D9J0ZX (open), 0D9J3ZX (percutaneous), 0D9J7ZX (via natural or artificial opening) and 0D9J8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 397 (Appendix Procedures with MCC), DRG 398 (Appendix Procedures with CC) and DRG 399 (Appendix Procedures without CC/MCC), under the surgical category “Appendix Procedures”.

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