Glaucoma w increased episcleral venous pressure, right eye

This diagnosis code signifies a specific type of glaucoma affecting the right eye, characterized by elevated pressure within the episcleral veins. This increased pressure impedes the outflow of aqueous humor, leading to elevated intraocular pressure and subsequent optic nerve damage. It is a secondary form of glaucoma, meaning it arises from an underlying condition causing the venous pressure elevation.

Use this code when documentation explicitly states glaucoma in the right eye is due to increased episcleral venous pressure. This often occurs in conditions like carotid-cavernous fistula, superior vena cava syndrome, or thyroid eye disease. Supporting documentation should include ophthalmological examination findings confirming glaucoma and a clear etiology linking it to elevated episcleral venous pressure.

• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Always code the underlying condition causing the increased episcleral venous pressure first, followed by this glaucoma code.
• Do not confuse with primary open-angle glaucoma or other secondary glaucomas without documented episcleral venous pressure involvement.
