About 09HY0YZ

09HY0YZ is the ICD-10-PCS code for a insertion procedure on the sinus 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 sinusotomy, not otherwise specified, the ICD-9-CM procedure title it maps to (22.50).

For a different body part, codes include 09HH0YZ (right ear), 09HJ0YZ (left ear) and 09HK0YZ (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09HY3YZ (percutaneous), 09HY4YZ (percutaneous endoscopic), 09HY7YZ (via natural or artificial opening) and 09HY8YZ (via natural or artificial opening endoscopic).

With a different device, use 09HY01Z (radioactive element).

It is an operating-room procedure in the MS-DRG logic for DRG 135 (Sinus and Mastoid Procedures with CC/MCC) and DRG 136 (Sinus and Mastoid Procedures without CC/MCC), under the surgical category “Sinus and Mastoid Procedures”.

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