About 0QJY4ZZ

0QJY4ZZ is the ICD-10-PCS code for a inspection procedure on the lower bone 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 diagnostic procedures on bone, not elsewhere classified, femur, diagnostic procedures on bone, not elsewhere classified, patella, diagnostic procedures on bone, not elsewhere classified, tibia and fibula and 2 more, the ICD-9-CM procedure titles it maps to (78.85, 78.86, 78.87 and 2 more).

The same procedure with a different approach is coded 0QJY0ZZ (open), 0QJY3ZZ (percutaneous) and 0QJYXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 477 (Biopsies of Musculoskeletal System and Connective Tissue with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 478 (Biopsies of Musculoskeletal System and Connective Tissue with CC) and DRG 479 (Biopsies of Musculoskeletal System and Connective Tissue without CC/MCC), under the surgical category “Biopsies of Musculoskeletal System and Connective Tissue”.

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