Mycotic corneal ulcer, bilateral

This code signifies a fungal infection of the cornea affecting both eyes. It involves an inflammatory and ulcerative process on the corneal surface caused by various fungal species, leading to significant vision impairment if untreated.

Use this code when documentation explicitly states a mycotic (fungal) corneal ulcer is present in both the right and left eyes. This diagnosis is typically confirmed through corneal scrapings and fungal cultures.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code (H16.061 or H16.062).
• Do not confuse with bacterial or viral corneal ulcers; specific pathogen identification is crucial.
• Code any underlying systemic fungal infection or predisposing factors (e.g., immunocompromised state) as additional diagnoses.
