About 0QSN4Z2

0QSN4Z2 is the ICD-10-PCS code for a reposition procedure on the right metatarsal using a percutaneous endoscopic approach (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 closed reduction of fracture without internal fixation, tarsals and metatarsals, the ICD-9-CM procedure title it maps to (79.07).

For a different body part, codes include 0QSP4Z2 (left metatarsal).

The same procedure with a different approach is coded 0QSN0Z2 (open), 0QSN3Z2 (percutaneous) and 0QSNXZ2 (external).

With a different device, use 0QSN442 (internal fixation device) and 0QSN452 (external fixation device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
