Valid for Submission
H10.509 is a billable diagnosis code used to specify a medical diagnosis of unspecified blepharoconjunctivitis, unspecified eye. The code H10.509 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 H10.509 might also be used to specify conditions or terms like blepharoconjunctivitis, marginal corneal infiltrate, marginal corneal infiltrate associated with blepharoconjunctivitis, rosacea blepharoconjunctivitis or rosacea conjunctivitis.
Unspecified diagnosis codes like H10.509 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Marginal corneal infiltrate
- Marginal corneal infiltrate associated with blepharoconjunctivitis
- Rosacea blepharoconjunctivitis
- Rosacea conjunctivitis

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert H10.509 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code H10.509 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
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.
