About 0SJC4ZZ

0SJC4ZZ is the ICD-10-PCS code for a inspection procedure on the right knee joint using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to Arthroscopy, knee, the ICD-9-CM procedure title it maps to (80.26).

For a different body part, codes include 0SJ04ZZ (lumbar vertebral joint), 0SJ24ZZ (lumbar vertebral disc), 0SJ34ZZ (lumbosacral joint), 0SJ44ZZ (lumbosacral disc), 0SJ54ZZ (sacrococcygeal joint), 0SJ64ZZ (coccygeal joint) and 15 more.

The same procedure with a different approach is coded 0SJC0ZZ (open), 0SJC3ZZ (percutaneous) and 0SJCXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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