Scleritis with corneal involvement, left eye

This code describes inflammation of the sclera (the white outer layer of the eyeball) that has spread to involve the cornea of the left eye. Scleritis with corneal involvement can lead to significant pain, vision impairment, and potential complications if not treated.

Use this code when documentation specifies scleritis affecting the left eye, with explicit mention of corneal involvement. This diagnosis is typically supported by an ophthalmologist's examination findings, including slit-lamp examination and detailed notes on the extent of inflammation.

• Ensure the documentation clearly specifies "left eye" and "corneal involvement" to support this specific laterality and manifestation.
• Distinguish from episcleritis, which is a less severe, superficial inflammation and coded differently.
• Code any underlying systemic conditions (e.g., autoimmune diseases) that may be causing the scleritis as additional diagnoses.
