About 08BY8ZX

08BY8ZX is the ICD-10-PCS code for a excision procedure on the left lacrimal duct using a via natural or artificial opening endoscopic 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 lacrimal sac, the ICD-9-CM procedure title it maps to (09.12).

For a different body part, codes include 08BX8ZX (right lacrimal duct).

The same procedure with a different approach is coded 08BY0ZX (open), 08BY3ZX (percutaneous) and 08BY7ZX (via natural or artificial opening).

It is an operating-room procedure in the MS-DRG logic for DRG 115 (Extraocular Procedures Except Orbit), 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 categories “Extraocular Procedures Except Orbit” and “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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