Zoster scleritis

This code identifies inflammation of the sclera, the white outer layer of the eye, specifically caused by the varicella-zoster virus (shingles). It represents a complication of herpes zoster ophthalmicus affecting the structural integrity of the eye.

Assign this code when documentation clearly indicates scleritis as a direct result of a zoster infection. This typically occurs in patients with a history of shingles, particularly herpes zoster ophthalmicus, presenting with ocular pain, redness, and scleral inflammation.

• Ensure documentation specifies zoster as the causative agent for scleritis, not just general scleritis.
• Code any associated herpes zoster ophthalmicus (e.g., HZ.xx) if still active and relevant to the encounter.
• Do not confuse with other forms of scleritis (e.g., H15.0- for episcleritis or other scleritis not specified as zoster).
