About 0CLB8ZZ

0CLB8ZZ is the ICD-10-PCS code for a occlusion procedure on the right parotid duct using a via natural or artificial opening endoscopic approach. 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 0CLC8ZZ (left parotid duct).

The same procedure with a different approach is coded 0CLB0ZZ (open), 0CLB3ZZ (percutaneous), 0CLB4ZZ (percutaneous endoscopic) and 0CLB7ZZ (via natural or artificial opening).

With a different device, use 0CLB8DZ (intraluminal 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.
