About 0QNN4ZZ

0QNN4ZZ is the ICD-10-PCS code for a release procedure on the right metatarsal using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to other repair or plastic operations on bone, tarsals and metatarsals, the ICD-9-CM procedure title it maps to (78.48).

For a different body part, codes include 0QN04ZZ (lumbar vertebra), 0QN14ZZ (sacrum), 0QN24ZZ (right pelvic bone), 0QN34ZZ (left pelvic bone), 0QN44ZZ (right acetabulum), 0QN54ZZ (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0QNN0ZZ (open) and 0QNN3ZZ (percutaneous).

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.
