About 0QNS0ZZ

0QNS0ZZ is the ICD-10-PCS code for a release procedure on the coccyx using an open 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, other bones, the ICD-9-CM procedure title it maps to (78.49).

The same procedure with a different approach is coded 0QNS3ZZ (percutaneous) and 0QNS4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical category “Other Musculoskeletal System and Connective Tissue O.R. Procedures”.
