About 0PN04ZZ

0PN04ZZ is the ICD-10-PCS code for a release procedure on the sternum using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to other repair or plastic operations on bone, scapula, clavicle, and thorax [ribs and sternum], the ICD-9-CM procedure title it maps to (78.41).

For a different body part, codes include 0PN14ZZ (ribs, 1 to 2), 0PN24ZZ (ribs, 3 or more), 0PN34ZZ (cervical vertebra), 0PN44ZZ (thoracic vertebra), 0PN54ZZ (right scapula), 0PN64ZZ (left scapula) and 20 more.

The same procedure with a different approach is coded 0PN00ZZ (open) and 0PN03ZZ (percutaneous).

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 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and “Other O.R. Procedures for Injuries”.

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