About 0GJK4ZZ

0GJK4ZZ is the ICD-10-PCS code for a inspection procedure on the thyroid gland 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 0GJ04ZZ (pituitary gland), 0GJ14ZZ (pineal body), 0GJ54ZZ (adrenal gland), 0GJR4ZZ (parathyroid gland) and 0GJS4ZZ (endocrine gland).

The same procedure with a different approach is coded 0GJK0ZZ (open) and 0GJK3ZZ (percutaneous).

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. Procedures” and “Thyroid, Parathyroid and Thyroglossal Procedures”.

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