About 0SJN0ZZ

0SJN0ZZ is the ICD-10-PCS code for a inspection procedure on the left metatarsal-phalangeal joint using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other arthrotomy, foot and toe, the ICD-9-CM procedure title it maps to (80.18).

For a different body part, codes include 0SJ00ZZ (lumbar vertebral joint), 0SJ20ZZ (lumbar vertebral disc), 0SJ30ZZ (lumbosacral joint), 0SJ40ZZ (lumbosacral disc), 0SJ50ZZ (sacrococcygeal joint), 0SJ60ZZ (coccygeal joint) and 15 more.

The same procedure with a different approach is coded 0SJN3ZZ (percutaneous), 0SJN4ZZ (percutaneous endoscopic) and 0SJNXZZ (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” and “Other O.R. Procedures for Injuries”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
