ICD-10: H16.323

Clinical Description of ICD-10 Code H16.323: Diffuse Interstitial Keratitis, Bilateral

ICD-10 Code Overview
ICD-10 code H16.323 refers to "Diffuse interstitial keratitis, bilateral." This condition is characterized by inflammation of the cornea, specifically affecting the interstitial tissue, which is the area between the layers of the cornea. The bilateral aspect indicates that both eyes are affected.

Pathophysiology

Diffuse interstitial keratitis is often associated with infectious or inflammatory processes. The inflammation leads to the accumulation of immune cells and fluid in the corneal stroma, resulting in corneal opacification and potential vision impairment. This condition can be caused by various factors, including:

• Infectious agents: Such as viruses (e.g., herpes simplex virus), bacteria, or fungi.
• Systemic diseases: Conditions like syphilis or tuberculosis can lead to keratitis.
• Autoimmune disorders: Diseases such as rheumatoid arthritis or lupus may also contribute to the development of interstitial keratitis.

Clinical Presentation

Patients with bilateral diffuse interstitial keratitis may present with a range of symptoms, including:

• Visual disturbances: Blurred vision or decreased visual acuity due to corneal opacification.
• Ocular discomfort: Patients may experience pain, photophobia (sensitivity to light), and redness in the eyes.
• Tearing: Increased tear production may occur as a response to irritation.
• Corneal changes: Upon examination, the cornea may appear cloudy or have a "ground glass" appearance due to the interstitial edema.

Diagnosis

Diagnosis of diffuse interstitial keratitis typically involves:

• Patient history: A thorough review of symptoms and any underlying systemic conditions.
• Ocular examination: Slit-lamp examination is crucial for assessing the corneal condition and identifying the extent of keratitis.
• Laboratory tests: In some cases, cultures or serological tests may be performed to identify infectious agents or underlying systemic diseases.

Treatment

Management of bilateral diffuse interstitial keratitis focuses on addressing the underlying cause and alleviating symptoms. Treatment options may include:

• Topical corticosteroids: To reduce inflammation and control symptoms.
• Antibiotics or antivirals: If an infectious cause is identified, appropriate antimicrobial therapy is essential.
• Supportive care: Artificial tears and other lubricants may help relieve discomfort.

Prognosis

The prognosis for patients with diffuse interstitial keratitis varies depending on the underlying cause and the timeliness of treatment. Early intervention can lead to better visual outcomes, while untreated cases may result in significant corneal scarring and vision loss.

Conclusion

ICD-10 code H16.323 encapsulates a significant ocular condition that requires careful diagnosis and management. Understanding the clinical features, potential causes, and treatment options is essential for healthcare providers to ensure optimal patient care and outcomes. If you suspect diffuse interstitial keratitis in a patient, prompt referral to an ophthalmologist is advisable for further evaluation and management.

Diffuse interstitial keratitis (DIK) is a condition characterized by inflammation of the corneal stroma, which can lead to significant visual impairment if not properly managed. The ICD-10 code H16.323 specifically refers to bilateral diffuse interstitial keratitis. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this condition.
