About 08B10ZX

08B10ZX is the ICD-10-PCS code for a excision procedure on the left eye using an open 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 eyeball and orbit, the ICD-9-CM procedure title it maps to (16.23).

For a different body part, codes include 08B00ZX (right eye), 08BA0ZX (right choroid), 08BB0ZX (left choroid), 08BL0ZX (right extraocular muscle), 08BM0ZX (left extraocular muscle), 08BN0ZX (right upper eyelid) and 7 more.

The same procedure with a different approach is coded 08B13ZX (percutaneous) and 08B1XZX (external).

It is an operating-room procedure in the MS-DRG logic for DRG 113 (Orbital Procedures with CC/MCC) and DRG 114 (Orbital Procedures without CC/MCC), under the surgical category “Orbital Procedures”.

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