About 0C7C0ZZ

0C7C0ZZ is the ICD-10-PCS code for a dilation procedure on the left parotid duct using an open 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 0C7B0ZZ (right parotid duct) and 0C7S0ZZ (larynx).

The same procedure with a different approach is coded 0C7C3ZZ (percutaneous) and 0C7C7ZZ (via natural or artificial opening).

With a different device, use 0C7C0DZ (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.
