ICD-10 Code H16.061 – Mycotic corneal ulcer, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.061 – Mycotic corneal ulcer, right eye
What it is
H16.061 identifies a fungal infection causing an ulcer of the cornea in the right eye. Use it when documentation clearly states a mycotic corneal ulcer affecting that eye.
Clinical signs
Typical findings include a corneal ulcer with signs of infection such as pain, redness, tearing, photophobia, and decreased vision. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifies a mycotic, fungal, or fungal corneal ulcer in the right eye. It is appropriate when the provider documents corneal ulceration with fungal etiology and laterality.
If the note only says “corneal ulcer” without an organism, check documentation before assigning this code. You should also confirm that the right eye is identified, not the left or both eyes.
Do not use for
Do not use H16.061 for nonfungal corneal ulcers, corneal abrasions, or nonspecific keratitis. Check documentation if the infection type or eye laterality is unclear.
Coding tip
Assign the code only when the chart supports both fungal cause and right-eye laterality.
