Sclerosing keratitis, bilateral

This code describes a chronic inflammatory condition affecting both eyes, characterized by hardening and thickening of the sclera, the white outer layer of the eyeball. This sclerosing process can lead to significant ocular pain, vision impairment, and potentially globe perforation if severe.

Assign this code when documentation explicitly states "sclerosing keratitis" affecting both eyes. This diagnosis is typically made by an ophthalmologist based on slit-lamp examination findings and patient symptoms. Supporting documentation should detail the bilateral involvement.

• Ensure the documentation clearly specifies bilateral involvement; otherwise, use the appropriate unilateral code.
• Distinguish from other forms of keratitis (e.g., infectious, ulcerative) which have different code assignments.
• Look for associated systemic conditions, as sclerosing keratitis can be a manifestation of autoimmune diseases, and code those conditions separately if documented.
