ICD-10 Code H10.501 – Unspecified blepharoconjunctivitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.501 – Unspecified blepharoconjunctivitis, right eye
What it is
This code identifies inflammation involving both the eyelid margin and conjunctiva of the right eye, when the cause is not specified. Use it when documentation states blepharoconjunctivitis without a more exact type.
Clinical signs
Typical findings include red, irritated eye, eyelid swelling, crusting, itching, tearing, or discharge. Clinical features vary; refer to documentation.
When to use this code
Use H10.501 when the provider documents unspecified blepharoconjunctivitis affecting the right eye and does not identify a specific organism or allergic cause. It is appropriate for unilateral right-eye involvement in outpatient or inpatient records. You should code the documented laterality exactly as written.
Do not use for
Do not use this code if the record specifies allergic, viral, bacterial, or other named conjunctivitis. Check documentation if the condition is bilateral or if blepharitis or conjunctivitis is documented separately.
Coding tip
Verify laterality and whether the provider documented an unspecified versus specific type before assigning H10.501.
