About 0QNM4ZZ

0QNM4ZZ is the ICD-10-PCS code for a release procedure on the left tarsal 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 0QNM0ZZ (open) and 0QNM3ZZ (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.
