About 08123K4

08123K4 is the ICD-10-PCS code for a bypass procedure on the right anterior chamber using a percutaneous approach with nonautologous tissue substitute (qualifier: sclera). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to other scleral fistulizing procedure, the ICD-9-CM procedure title it maps to (12.69).

For a different body part, codes include 08133K4 (left anterior chamber).

With a different device, use 08123J4 (synthetic substitute) and 08123Z4 (no device).

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.
