About 08BTXZX

08BTXZX is the ICD-10-PCS code for a excision procedure on the left conjunctiva 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 conjunctiva, the ICD-9-CM procedure title it maps to (10.21).

It is an operating-room procedure in the MS-DRG logic for DRG 115 (Extraocular Procedures Except Orbit), under the surgical category “Extraocular Procedures Except Orbit”.

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