About 0SNF0ZZ

0SNF0ZZ is the ICD-10-PCS code for a release procedure on the right ankle joint 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 division of joint capsule, ligament, or cartilage, ankle, the ICD-9-CM procedure title it maps to (80.47).

For a different body part, codes include 0SN00ZZ (lumbar vertebral joint), 0SN20ZZ (lumbar vertebral disc), 0SN30ZZ (lumbosacral joint), 0SN40ZZ (lumbosacral disc), 0SN50ZZ (sacrococcygeal joint), 0SN60ZZ (coccygeal joint) and 15 more.

The same procedure with a different approach is coded 0SNF3ZZ (percutaneous), 0SNF4ZZ (percutaneous endoscopic) and 0SNFXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 492 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 493 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with CC), DRG 494 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur 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 “Lower Extremity and Humerus Procedures Except Hip, Foot and Femur”, “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.
