About 0F944ZX

0F944ZX is the ICD-10-PCS code for a drainage procedure on the gallbladder 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 percutaneous biopsy of gallbladder or bile ducts, the ICD-9-CM procedure title it maps to (51.12).

For a different body part, codes include 0F904ZX (liver), 0F914ZX (liver, right lobe), 0F924ZX (liver, left lobe), 0F954ZX (right hepatic duct), 0F964ZX (left hepatic duct), 0F974ZX (hepatic duct, common) and 6 more.

The same procedure with a different approach is coded 0F940ZX (open), 0F943ZX (percutaneous) and 0F948ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 420 (Hepatobiliary Diagnostic Procedures with MCC), DRG 421 (Hepatobiliary Diagnostic Procedures with CC) and DRG 422 (Hepatobiliary Diagnostic Procedures without CC/MCC), under the surgical category “Hepatobiliary Diagnostic Procedures”.

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