About X9HF01B

X9HF01B is the ICD-10-PCS code for a insertion procedure on the bilateral 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 X9HD01B (right inner ear) and X9HE01B (left 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.
