ICD-10 Code H10.029 – Other mucopurulent conjunctivitis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.029 – Other mucopurulent conjunctivitis, unspecified eye
What it is
This code identifies mucopurulent conjunctivitis affecting an unspecified eye when the record describes a bacterial-type conjunctival inflammation with mixed mucus and pus. Use it when laterality is not documented.
Clinical signs
Typical findings include red conjunctiva, discharge that is thick, yellow, or green, and eyelid crusting. Clinical features vary; refer to documentation.
When to use this code
Use H10.029 when the clinician documents other mucopurulent conjunctivitis and does not specify right, left, or bilateral eye involvement. It may fit office, urgent care, or emergency notes describing purulent conjunctival discharge without a more specific diagnosis. Check documentation if another conjunctivitis type is named.
Do not use for
Do not use this code for allergic, viral, or nonspecific conjunctivitis, or when laterality is clearly documented elsewhere. If the chart supports a different conjunctival disorder, code that condition instead.
Coding tip
Confirm both the conjunctivitis type and the eye laterality before assigning H10.029.
