ICD-10-PCS Code For Anterior Chamber Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0812 includes procedures performed to bypass the route of passage of the contents in the anterior chamber, right. These ICD-10-PCS codes are used for inpatient documentation when a clinician creates an alternative pathway for aqueous humor flow or otherwise alters the passage within the right anterior chamber to treat conditions such as glaucoma or traumatic aqueous outflow obstruction. Accurate coding within the ICD-10-PCS 0812 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Anterior Chamber Bypass Procedure Overview

Procedures in this group involve bypassing the normal route of passage of aqueous humor within the eye, specifically targeting the right anterior chamber. These procedures are performed on the eye body system and alter the route of flow to relieve pressure or reroute fluid. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the exact operation and supports appropriate case mix assignment.

When to Use

Use a code from this group when the operative intent is to bypass or reroute the normal flow of aqueous humor in the right anterior chamber. These codes apply when an inpatient procedure establishes an alternative passage to relieve intraocular pressure or restore fluid outflow.

Typical Clinical Scenarios

An elderly patient with advanced primary open-angle glaucoma on maximal medical therapy presents electively for surgical lowering of intraocular pressure because progressive visual field loss and uncontrolled IOP threaten remaining vision. In the inpatient setting the surgeon creates an alternative pathway from the right anterior chamber to the sclera to enhance aqueous outflow using a synthetic implant placed through a percutaneous approach to achieve sustained pressure reduction. Typical codes: 08123J4
A middle-aged patient sustains blunt ocular trauma to the right eye with hyphema and acute elevation of intraocular pressure that fails medical management, prompting urgent inpatient intervention to restore outflow and prevent optic nerve damage. The operative plan is to bypass the obstructed trabecular outflow by creating a right anterior chamber–to–sclera route via a percutaneous procedure using a nonautologous tissue substitute to reestablish drainage. Typical codes: 08123K4
A patient with prior failed glaucoma surgery develops scarring obstructing the previous outflow tract and presents for revision; the inpatient operation aims to create a new external bypass from the right anterior chamber to the sclera without implanting a substitute, performed percutaneously to reestablish aqueous drainage. Typical codes: 08123Z4
