About 08B9XZX

08B9XZX is the ICD-10-PCS code for a excision procedure on the left cornea using an external approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of cornea, the ICD-9-CM procedure title it maps to (11.22).

For a different body part, codes include 08B0XZX (right eye), 08B1XZX (left eye), 08B6XZX (right sclera), 08B7XZX (left sclera), 08B8XZX (right cornea), 08BNXZX (right upper eyelid) and 5 more.

It is an operating-room procedure in the MS-DRG logic for DRG 115 (Extraocular Procedures Except Orbit), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC) and DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC), under the surgical categories “Extraocular Procedures Except Orbit”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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