About 0QSN042

0QSN042 is the ICD-10-PCS code for a reposition procedure on the right metatarsal using an open approach with internal fixation device (qualifier: sesamoid bone(s) 1st toe). In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to open reduction of fracture with internal fixation, tarsals and metatarsals, the ICD-9-CM procedure title it maps to (79.37).

For a different body part, codes include 0QSP042 (left metatarsal).

The same procedure with a different approach is coded 0QSN342 (percutaneous) and 0QSN442 (percutaneous endoscopic).

With a different device, use 0QSN052 (external fixation device) and 0QSN0Z2 (no device).

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 was added in FY2018, effective October 1, 2017.
