Valid for Submission
B30.9 is a billable diagnosis code used to specify a medical diagnosis of viral conjunctivitis, unspecified. The code B30.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code B30.9 might also be used to specify conditions or terms like acute epidemic conjunctivitis, bilateral viral conjunctivitis, conjunctivitis of left eye caused by virus, conjunctivitis of right eye caused by virus or viral conjunctivitis.
Unspecified diagnosis codes like B30.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
Conjunctivitis is the medical name for pink eye. It involves inflammation of the outer layer of the eye and inside of the eyelid. It can cause swelling, itching, burning, discharge, and redness. Causes include
- Bacterial or viral infection
- Substances that cause irritation
- Contact lens products, eye drops, or eye ointments
Pink eye usually does not affect vision. Infectious pink eye can easily spread from one person to another. The infection will clear in most cases without medical care, but bacterial pink eye needs treatment with antibiotic eye drops or ointment.
