About 09HD0SZ

09HD0SZ is the ICD-10-PCS code for a insertion procedure on the right inner ear using an open approach with hearing 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 implantation or replacement of cochlear prosthetic device, not otherwise specified, the ICD-9-CM procedure title it maps to (20.96).

For a different body part, codes include 09HE0SZ (left inner ear).

The same procedure with a different approach is coded 09HD3SZ (percutaneous) and 09HD4SZ (percutaneous endoscopic).

With a different device, use 09HD01Z (radioactive element), 09HD04Z (hearing device, bone conduction), 09HD05Z (hearing device, single channel cochlear prosthesis) and 09HD06Z (hearing device, multiple channel cochlear prosthesis).

It is an operating-room procedure in the MS-DRG logic for DRG 140 (Major Head and Neck Procedures with MCC), DRG 141 (Major Head and Neck Procedures with CC) and DRG 142 (Major Head and Neck Procedures without CC/MCC), under the surgical category “Major Head and Neck Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
