Scleritis with corneal involvement, unspecified eye

This code signifies inflammation of the sclera (the white outer layer of the eye) that has extended to affect the cornea, the transparent front part of the eye. This condition can lead to pain, redness, and vision impairment due to the combined inflammatory processes in both structures. The "unspecified eye" designation indicates that the laterality of the affected eye is not documented.

Use this code when documentation clearly states scleritis with corneal involvement, but the medical record does not specify whether the right, left, or both eyes are affected. This code is appropriate for initial encounters or follow-up visits where the laterality remains undetermined. Supporting documentation would include ophthalmological exam findings detailing both scleral and corneal inflammation.

• Avoid using this code if laterality (right, left, or bilateral) is documented; instead, choose the more specific H15.041, H15.042, or H15.043.
• Ensure the documentation explicitly links the corneal involvement to the scleritis, rather than two separate conditions.
• Consider sequencing this code after any underlying systemic conditions (e.g., autoimmune diseases) that may be causing the scleritis.
