About 0PHS45Z

0PHS45Z is the ICD-10-PCS code for a insertion procedure on the left thumb phalanx using a percutaneous endoscopic approach with external fixation device. 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, other bones, the ICD-9-CM procedure title it maps to (78.19).

For a different body part, codes include 0PHC45Z (right humeral head), 0PHD45Z (left humeral head), 0PHF45Z (right humeral shaft), 0PHG45Z (left humeral shaft), 0PHH45Z (right radius), 0PHJ45Z (left radius) and 9 more.

The same procedure with a different approach is coded 0PHS05Z (open) and 0PHS35Z (percutaneous).

With a different device, use 0PHS44Z (internal fixation device).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures 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 “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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