About 0WB84ZZ

0WB84ZZ is the ICD-10-PCS code for a excision procedure on the chest wall using a percutaneous endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision or destruction of lesion of chest wall, the ICD-9-CM procedure title it maps to (34.4).

For a different body part, codes include 0WB04ZZ (head), 0WB24ZZ (face), 0WB34ZZ (oral cavity and throat), 0WB44ZZ (upper jaw), 0WB54ZZ (lower jaw), 0WB64ZZ (neck) and 7 more.

The same procedure with a different approach is coded 0WB80ZZ (open), 0WB83ZZ (percutaneous) and 0WB8XZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 495 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with MCC), DRG 496 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC) and DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Local Excision and Removal of Internal Fixation Devices Except Hip and Femur”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 3 more.

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