ICD Coding
  • ICD-10-AM Codes: H10, H13.1, H13.2, H15.2
Brief description

Conjunctivitis is inflammation of the conjunctiva of the eye, due to infection or other causes.  The conjunctiva is the clear, thin membrane that covers part of the front surface of the eye and the inner surface of the eyelids.

Conjunctivitis may be acute or chronic.  Acute episodes of infectious and irritant-caused conjunctivitis generally resolve completely.

Confirming the diagnosis

The diagnosis is made on clinical grounds and can be made by a treating GP.

The relevant medical specialist is an ophthalmologist.

Additional diagnoses covered by SOP
  • blepharoconjunctivitis
  • keratoconjunctivitis
Conditions not covered by SOP
  • blepharitis without conjunctivitis*
  • keratitis without conjunctivitis#

* Another SOP applies

Clinical onset

Clinical onset will vary with the underlying cause and nature of the condition.  This condition can be a one-off acute condition (from e.g. infection or an irritant), or there can be recurrent discrete episodes (with different causes), or there can be an underlying problem resulting in a chronic or relapsing course.  In the absence of an underlying chronic cause each episode will represent a new clinical onset.  For chronic or relapsing conjunctivitis, including allergic conjunctivitis, the clinical onset will be the first episode triggered by the underlying problem.

Clinical worsening

Clinical worsening will generally only be relevant for chronic or relapsing conjunctivitis.
