About 0SGN04Z

0SGN04Z is the ICD-10-PCS code for a fusion procedure on the left metatarsal-phalangeal joint using an open approach with internal 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 0SG504Z (sacrococcygeal joint), 0SG704Z (right sacroiliac joint), 0SG804Z (left sacroiliac joint), 0SG904Z (right hip joint), 0SGB04Z (left hip joint), 0SGC04Z (right knee joint) and 10 more.

The same procedure with a different approach is coded 0SGN34Z (percutaneous) and 0SGN44Z (percutaneous endoscopic).

With a different device, use 0SGN03Z (internal fixation device, sustained compression), 0SGN05Z (external fixation device), 0SGN07Z (autologous tissue substitute), 0SGN0JZ (synthetic substitute) and 0SGN0KZ (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.
