ICD-10: H10

Conjunctivitis, commonly known as "pink eye," is an inflammation of the conjunctiva, the thin, transparent membrane that covers the white part of the eyeball and lines the inner surface of the eyelids. The condition can be caused by various factors, including infections, allergies, and irritants. The ICD-10 code for conjunctivitis falls under the range H10-H13, specifically categorized as H10 for disorders of the conjunctiva.

Clinical Description of Conjunctivitis (ICD-10 Code H10)

Types of Conjunctivitis

1. Acute Conjunctivitis (H10.0): This type is often viral or bacterial in origin and is characterized by a sudden onset of symptoms. Common symptoms include redness, swelling, and discharge from the eye. Viral conjunctivitis is typically associated with upper respiratory infections, while bacterial conjunctivitis may present with purulent discharge.

2. Allergic Conjunctivitis (H10.1): This form occurs due to allergic reactions to substances such as pollen, dust mites, or pet dander. Symptoms include itching, redness, and watery discharge. It is often seasonal and can be associated with other allergic conditions like hay fever.

3. Other Conjunctivitis (H10.8): This category includes various forms of conjunctivitis that do not fit into the acute or allergic classifications. It may encompass less common causes such as chemical irritants or specific infections.

4. Unspecified Conjunctivitis (H10.9): This code is used when the specific type of conjunctivitis is not clearly defined or diagnosed. It is a general classification for cases where the cause of inflammation is unknown.

Symptoms

The symptoms of conjunctivitis can vary depending on the underlying cause but generally include:
- Redness of the eye
- Increased tearing or discharge (which may be watery or purulent)
- Itching or burning sensation
- Swelling of the conjunctiva
- Sensitivity to light

Diagnosis

Diagnosis typically involves a thorough clinical examination, including:
- Patient history to identify symptoms and potential exposure to allergens or infectious agents.
- Physical examination of the eyes to assess redness, discharge, and other signs of inflammation.
- In some cases, laboratory tests may be conducted to identify the causative agent, especially in bacterial conjunctivitis.

Treatment

Treatment for conjunctivitis varies based on the cause:
- Viral Conjunctivitis: Often self-limiting; symptomatic relief with cool compresses and artificial tears is recommended.
- Bacterial Conjunctivitis: Usually treated with antibiotic eye drops or ointments.
- Allergic Conjunctivitis: Managed with antihistamines or anti-inflammatory eye drops to alleviate symptoms.

Prevention

Preventive measures include:
- Practicing good hygiene, such as frequent handwashing.
- Avoiding touching the eyes with unwashed hands.
- Staying away from known allergens and irritants.

Conclusion

Conjunctivitis is a common eye condition that can significantly impact quality of life due to its symptoms. Understanding the different types and their respective ICD-10 codes (H10.0 for acute, H10.1 for allergic, H10.8 for other, and H10.9 for unspecified) is crucial for accurate diagnosis and treatment. Early intervention and proper management can help alleviate symptoms and prevent complications associated with this condition.

Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the membrane that lines the eyelid and covers the white part of the eyeball. The ICD-10-CM code for conjunctivitis is H10, which encompasses various types of conjunctivitis, including allergic, bacterial, viral, and other forms. The criteria for diagnosing conjunctivitis under this code typically involve a combination of clinical evaluation, patient history, and specific symptoms.
