About 09HH0YZ

09HH0YZ is the ICD-10-PCS code for a insertion procedure on the right ear using an open approach with other device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to other operations on middle and inner ear, the ICD-9-CM procedure title it maps to (20.99).

For a different body part, codes include 09HJ0YZ (left ear), 09HK0YZ (nasal mucosa and soft tissue) and 09HY0YZ (sinus).

The same procedure with a different approach is coded 09HH3YZ (percutaneous), 09HH4YZ (percutaneous endoscopic), 09HH7YZ (via natural or artificial opening) and 09HH8YZ (via natural or artificial opening endoscopic).

With a different device, use 09HH01Z (radioactive element).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

It was added in FY2018, effective October 1, 2017.
