About 08N8XZZ

08N8XZZ is the ICD-10-PCS code for a release procedure on the right cornea using an external approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to other repair of cornea, the ICD-9-CM procedure title it maps to (11.59).

For a different body part, codes include 08N0XZZ (right eye), 08N1XZZ (left eye), 08N6XZZ (right sclera), 08N7XZZ (left sclera), 08N9XZZ (left cornea), 08NNXZZ (right upper eyelid) and 5 more.

It is an operating-room procedure in the MS-DRG logic for DRG 116 (Intraocular Procedures with CC/MCC), DRG 117 (Intraocular Procedures without CC/MCC), 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) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Intraocular Procedures”, “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.
