ICD-10 Code H10.023 – Other mucopurulent conjunctivitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.023 – Other mucopurulent conjunctivitis, bilateral
What it is
This code identifies mucopurulent conjunctivitis affecting both eyes when the provider documents a bilateral infection or inflammation of the conjunctiva with mucus and pus. Use it for the specific bilateral form, not a nonspecific eye discharge.
Clinical signs
Typical findings include red conjunctiva, sticky or thick discharge, and eyelid crusting. Clinical features vary; refer to documentation if laterality, severity, or cause is unclear.
When to use this code
Use H10.023 when the record clearly states other mucopurulent conjunctivitis in both eyes. This is appropriate when the clinician documents bilateral conjunctival inflammation with mucopurulent drainage and does not assign a more specific conjunctivitis diagnosis. Check documentation if the cause is infectious, allergic, or unspecified.
Do not use for
Do not use this code for unilateral conjunctivitis or for conjunctivitis with a different documented type, such as viral or allergic. Do not assign it when the chart only notes eye redness or discharge without a diagnosis.
Coding tip
Verify both laterality and the exact conjunctivitis type before coding; if the note does not support bilateral mucopurulent disease, check documentation.
