About 0SNL4ZZ

0SNL4ZZ is the ICD-10-PCS code for a release procedure on the left tarsometatarsal 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, foot and toe, the ICD-9-CM procedure title it maps to (80.48).

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 0SNL0ZZ (open), 0SNL3ZZ (percutaneous) and 0SNLXZZ (external).

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.
