ICD-10 Code H16.053 – Mooren’s corneal ulcer, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.053 – Mooren’s corneal ulcer, bilateral
What it is
This code identifies Mooren’s corneal ulcer affecting both eyes. It refers to a painful peripheral corneal ulceration that is not caused by another known systemic or infectious condition.
Clinical signs
Typical findings include peripheral corneal ulceration, eye pain, redness, tearing, and light sensitivity. Clinical features vary; refer to documentation.
When to use this code
Use H16.053 when the provider documents Mooren’s corneal ulcer in both eyes. Apply it when the diagnosis is confirmed in the chart and laterality is clearly bilateral.
Choose this code for a bilateral corneal ulcer specifically identified as Mooren’s. Check documentation if the record only says corneal ulcer, peripheral ulcer, or autoimmune keratitis.
Do not use for
Do not use this code for infectious corneal ulcers, traumatic corneal injury, or nonspecific keratitis. Check documentation if the cause or laterality is unclear.
Coding tip
Verify both laterality and the exact phrase “Mooren’s corneal ulcer” before assigning H16.053.
