About X9HD01B

X9HD01B is the ICD-10-PCS code for a insertion procedure on the right inner ear using an open approach with infusion device, temporary (qualifier: new technology group 11). 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.

For a different body part, codes include X9HE01B (left inner ear) and X9HF01B (bilateral inner ear).

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 was added in FY2027, effective October 1, 2026.
