About 0CLC4CZ

0CLC4CZ is the ICD-10-PCS code for a occlusion procedure on the left parotid duct using a percutaneous endoscopic approach with extraluminal device. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other operations on salivary gland or duct, the ICD-9-CM procedure title it maps to (26.99).

For a different body part, codes include 0CLB4CZ (right parotid duct).

The same procedure with a different approach is coded 0CLC0CZ (open) and 0CLC3CZ (percutaneous).

With a different device, use 0CLC4DZ (intraluminal device) and 0CLC4ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 139 (Salivary Gland Procedures), under the surgical category “Salivary Gland Procedures”.

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