ICD-10 Code H10.8 – Other conjunctivitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.8 – Other conjunctivitis
What it is
H10.8 identifies conjunctivitis that does not fit a more specific category. Use it for inflammation of the conjunctiva when the record supports conjunctivitis but does not name a more precise type.
Clinical signs
Typical findings include conjunctival redness, irritation, tearing, and discharge. Clinical features vary; refer to documentation when the note does not clearly describe the cause or subtype.
When to use this code
Use H10.8 when the clinician documents conjunctivitis and the chart does not specify allergic, bacterial, viral, or another defined form. It may also fit cases labeled as “other” or “unspecified type not elsewhere classified” if that is the documented diagnosis.
Do not use for
Do not use this code when a more specific conjunctivitis diagnosis is documented, such as allergic or viral conjunctivitis. Check documentation if the note describes a nonconjunctival eye disorder or an uncertain eye irritation only.
Coding tip
Code the most specific conjunctivitis type documented; if the record is vague, query or code only what is clearly supported.
