About 08BL0ZX

08BL0ZX is the ICD-10-PCS code for a excision procedure on the right extraocular muscle 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 extraocular muscle or tendon, the ICD-9-CM procedure title it maps to (15.01).

For a different body part, codes include 08B00ZX (right eye), 08B10ZX (left eye), 08BA0ZX (right choroid), 08BB0ZX (left choroid), 08BM0ZX (left extraocular muscle), 08BN0ZX (right upper eyelid) and 7 more.

The same procedure with a different approach is coded 08BL3ZX (percutaneous).

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.
