ICD-10 Code H10.02 – Other mucopurulent conjunctivitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.02 – Other mucopurulent conjunctivitis
What it is
Use this code for conjunctival inflammation with mucopurulent discharge when the record does not identify a more specific type. It refers to an eye infection or irritation involving mucus and pus-like drainage.
Clinical signs
Typical findings include red conjunctiva, eye discharge, and irritation or crusting of the eyelids. Clinical features vary; refer to documentation.
When to use this code
Assign H10.02 when the provider documents other mucopurulent conjunctivitis and does not specify a different conjunctivitis category. Use it for cases with mucopurulent drainage that are not better captured by a more specific code. Check documentation if the cause, eye laterality, or acuity is unclear.
Do not use for
Do not use this code for allergic, viral, or unspecified conjunctivitis when the record supports a different diagnosis. Avoid it if the provider documents a more specific infectious organism or another eye disorder.
Coding tip
Code only what the provider documents, and query for laterality or specificity when the note is incomplete.
