About 0F520ZZ

0F520ZZ is the ICD-10-PCS code for a destruction procedure on the liver, left lobe using an open approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to open ablation of liver lesion or tissue, other and unspecified ablation of liver lesion or tissue and other destruction of lesion of liver, the ICD-9-CM procedure titles it maps to (50.23, 50.26 and 50.29).

For a different body part, codes include 0F500ZZ (liver), 0F510ZZ (liver, right lobe), 0F540ZZ (gallbladder), 0F550ZZ (right hepatic duct), 0F560ZZ (left hepatic duct), 0F570ZZ (hepatic duct, common) and 6 more.

The same procedure with a different approach is coded 0F523ZZ (percutaneous) and 0F524ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), DRG 405 (Pancreas, Liver and Shunt Procedures with MCC), DRG 406 (Pancreas, Liver and Shunt Procedures with CC) and DRG 407 (Pancreas, Liver and Shunt Procedures without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures” and “Pancreas, Liver and Shunt Procedures”.

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