About 0WJ64ZZ

0WJ64ZZ is the ICD-10-PCS code for a inspection procedure on the neck 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 other diagnostic procedures on thyroid and parathyroid glands, the ICD-9-CM procedure title it maps to (06.19).

For a different body part, codes include 0WJ04ZZ (head), 0WJ14ZZ (cranial cavity), 0WJ24ZZ (face), 0WJ34ZZ (oral cavity and throat), 0WJ44ZZ (upper jaw), 0WJ54ZZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WJ60ZZ (open), 0WJ63ZZ (percutaneous) and 0WJ6XZZ (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 625 (Thyroid, Parathyroid and Thyroglossal Procedures with MCC), DRG 626 (Thyroid, Parathyroid and Thyroglossal Procedures with CC) and DRG 627 (Thyroid, Parathyroid and Thyroglossal Procedures without CC/MCC), under the surgical categories “Other Musculoskeletal System and Connective Tissue O.R.
