About 0SNC4ZZ

0SNC4ZZ is the ICD-10-PCS code for a release procedure on the right knee joint 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 division of joint capsule, ligament, or cartilage, knee, the ICD-9-CM procedure title it maps to (80.46).

For a different body part, codes include 0SN04ZZ (lumbar vertebral joint), 0SN24ZZ (lumbar vertebral disc), 0SN34ZZ (lumbosacral joint), 0SN44ZZ (lumbosacral disc), 0SN54ZZ (sacrococcygeal joint), 0SN64ZZ (coccygeal joint) and 15 more.

The same procedure with a different approach is coded 0SNC0ZZ (open), 0SNC3ZZ (percutaneous) and 0SNCXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 400 (Knee Procedures with Principal Diagnosis of Infection), DRG 488 (Knee Procedures without Principal Diagnosis of Infection with CC/MCC), DRG 489 (Knee Procedures without Principal Diagnosis of Infection 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 “Knee Procedures with Principal Diagnosis of Infection”, “Knee Procedures without Principal Diagnosis of Infection”, “Other O.R.
