About 09HH4YZ
09HH4YZ is the ICD-10-PCS code for a insertion procedure on the right ear 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 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 09HJ4YZ (left ear), 09HK4YZ (nasal mucosa and soft tissue) and 09HY4YZ (sinus).
The same procedure with a different approach is coded 09HH0YZ (open), 09HH3YZ (percutaneous), 09HH7YZ (via natural or artificial opening) and 09HH8YZ (via natural or artificial opening endoscopic).
With a different device, use 09HH41Z (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.
