Neurotrophic keratoconjunctivitis, right eye

This code signifies a degenerative corneal disorder affecting the right eye, characterized by impaired corneal sensation due to damage to the trigeminal nerve. This nerve damage leads to reduced tear production, epithelial breakdown, and potential ulceration, compromising the integrity of the ocular surface.

Apply this code when documentation specifies neurotrophic keratoconjunctivitis affecting the patient's right eye. This diagnosis is typically supported by findings of decreased corneal sensation, persistent epithelial defects, and a history of trigeminal nerve dysfunction or damage.

• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Distinguish from other forms of keratoconjunctivitis (e.g., dry eye, allergic) which have different underlying etiologies.
• Consider co-reporting codes for underlying conditions causing the trigeminal nerve damage, if applicable and documented.
