About 0SGN45Z

0SGN45Z is the ICD-10-PCS code for a fusion procedure on the left metatarsal-phalangeal joint using a percutaneous endoscopic approach with external fixation device. In ICD-10-PCS, fusion means joining together portions of an articular body part rendering the articular body part immobile.

In plain terms, this corresponds to metatarsophalangeal fusion, the ICD-9-CM procedure title it maps to (81.16).

For a different body part, codes include 0SG945Z (right hip joint), 0SGB45Z (left hip joint), 0SGC45Z (right knee joint), 0SGD45Z (left knee joint), 0SGF45Z (right ankle joint), 0SGG45Z (left ankle joint) and 7 more.

The same procedure with a different approach is coded 0SGN05Z (open) and 0SGN35Z (percutaneous).

With a different device, use 0SGN43Z (internal fixation device, sustained compression), 0SGN44Z (internal fixation device), 0SGN47Z (autologous tissue substitute), 0SGN4JZ (synthetic substitute) and 0SGN4KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 503 (Foot Procedures with MCC), DRG 504 (Foot Procedures with CC), DRG 505 (Foot 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 “Foot 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.
