About 0G8J4ZZ

0G8J4ZZ is the ICD-10-PCS code for a division procedure on the thyroid gland isthmus using a percutaneous endoscopic approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to division of thyroid isthmus, the ICD-9-CM procedure title it maps to (06.91).

For a different body part, codes include 0G804ZZ (pituitary gland).

The same procedure with a different approach is coded 0G8J0ZZ (open) and 0G8J3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for 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 category “Thyroid, Parathyroid and Thyroglossal Procedures”.

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