About 0PHF0CZ

0PHF0CZ is the ICD-10-PCS code for a insertion procedure on the right humeral shaft using an open approach with external fixation device, ring. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to application of external fixator device, humerus and application of external fixator device, ring system, the ICD-9-CM procedure titles it maps to (78.12 and 84.72).

For a different body part, codes include 0PHC0CZ (right humeral head), 0PHD0CZ (left humeral head), 0PHG0CZ (left humeral shaft), 0PHH0CZ (right radius), 0PHJ0CZ (left radius), 0PHK0CZ (right ulna) and 1 more.

The same procedure with a different approach is coded 0PHF3CZ (percutaneous) and 0PHF4CZ (percutaneous endoscopic).

With a different device, use 0PHF04Z (internal fixation device), 0PHF05Z (external fixation device), 0PHF06Z (internal fixation device, intramedullary), 0PHF07Z (internal fixation device, intramedullary limb lengthening), 0PHF08Z (external fixation device, limb lengthening), 0PHF0BZ (external fixation device, monoplanar) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 492 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 493 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with CC), DRG 494 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Lower Extremity and Humerus Procedures Except Hip, Foot and Femur”, “Other O.R. Procedures for Injuries” and “Other O.R.
