About 0C7C7ZZ

0C7C7ZZ is the ICD-10-PCS code for a dilation procedure on the left parotid duct using a via natural or artificial opening approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to Probing of salivary duct, the ICD-9-CM procedure title it maps to (26.91).

For a different body part, codes include 0C7B7ZZ (right parotid duct), 0C7M7ZZ (pharynx) and 0C7S7ZZ (larynx).

The same procedure with a different approach is coded 0C7C0ZZ (open) and 0C7C3ZZ (percutaneous).

With a different device, use 0C7C7DZ (intraluminal device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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