About 0SN50ZZ

0SN50ZZ is the ICD-10-PCS code for a release procedure on the sacrococcygeal 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, other specified sites, the ICD-9-CM procedure title it maps to (80.49).

For a different body part, codes include 0SN00ZZ (lumbar vertebral joint), 0SN20ZZ (lumbar vertebral disc), 0SN30ZZ (lumbosacral joint), 0SN40ZZ (lumbosacral disc), 0SN60ZZ (coccygeal joint), 0SN70ZZ (right sacroiliac joint) and 15 more.

The same procedure with a different approach is coded 0SN53ZZ (percutaneous), 0SN54ZZ (percutaneous endoscopic) and 0SN5XZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “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.
