Diffuse interstitial keratitis, right eye

This code signifies a non-ulcerative inflammation of the corneal stroma, characterized by diffuse infiltration of inflammatory cells without primary involvement of the epithelium or endothelium, specifically affecting the right eye. This condition often results in corneal opacification and can impair vision.

Apply this code when documentation explicitly states diffuse interstitial keratitis affecting the right eye. This diagnosis is typically made following a slit-lamp examination revealing stromal haze and cellular infiltration. Ensure the laterality is clearly specified as "right eye."

• Differentiate from other forms of keratitis, such as ulcerative or punctate, which have distinct codes.
• Always confirm laterality; separate codes exist for the left and bilateral eyes.
• Look for associated systemic conditions, as interstitial keratitis can be a manifestation of underlying autoimmune diseases or infections.
