About 09HE3SZ
09HE3SZ is the ICD-10-PCS code for a insertion procedure on the left inner ear using a percutaneous 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 09HD3SZ (right inner ear).
The same procedure with a different approach is coded 09HE0SZ (open) and 09HE4SZ (percutaneous endoscopic).
With a different device, use 09HE31Z (radioactive element), 09HE34Z (hearing device, bone conduction), 09HE35Z (hearing device, single channel cochlear prosthesis) and 09HE36Z (hearing device, multiple channel cochlear prosthesis).
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 has been valid since ICD-10-PCS took effect on October 1, 2015.
