About 09HK4YZ

09HK4YZ is the ICD-10-PCS code for a insertion procedure on the nasal mucosa and soft tissue using a percutaneous endoscopic 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 incision of nose, the ICD-9-CM procedure title it maps to (21.1).

For a different body part, codes include 09HH4YZ (right ear), 09HJ4YZ (left ear) and 09HY4YZ (sinus).

The same procedure with a different approach is coded 09HK0YZ (open), 09HK3YZ (percutaneous), 09HK7YZ (via natural or artificial opening) and 09HK8YZ (via natural or artificial opening endoscopic).

With a different device, use 09HK41Z (radioactive element).

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

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