About 0CLC4DZ
0CLC4DZ is the ICD-10-PCS code for a occlusion procedure on the left parotid duct using a percutaneous endoscopic approach with intraluminal 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 0CLB4DZ (right parotid duct).
The same procedure with a different approach is coded 0CLC0DZ (open), 0CLC3DZ (percutaneous), 0CLC7DZ (via natural or artificial opening) and 0CLC8DZ (via natural or artificial opening endoscopic).
With a different device, use 0CLC4CZ (extraluminal 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.
