ICD-10: H16.42

Pannus, specifically referred to in the ICD-10-CM as H16.42, is a condition characterized by the growth of vascularized granulation tissue over the cornea. This condition can significantly impact vision and is often associated with various underlying causes, including chronic inflammation, trauma, or certain systemic diseases.

Clinical Description of Pannus (Corneal)

Definition

Pannus is defined as a pathological condition where there is an abnormal proliferation of blood vessels and connective tissue on the corneal surface. This growth can lead to opacification of the cornea, resulting in visual impairment. The term "pannus" is derived from the Latin word for "cloth" or "covering," reflecting the appearance of the tissue over the cornea.

Etiology

Pannus can arise from several factors, including:
- Chronic Inflammation: Conditions such as keratitis or conjunctivitis can lead to persistent inflammation, promoting the growth of pannus.
- Trauma: Physical injury to the eye can trigger a healing response that results in the formation of pannus.
- Systemic Diseases: Conditions like rheumatoid arthritis or other autoimmune disorders may predispose individuals to develop corneal pannus due to systemic inflammation.

Symptoms

Patients with corneal pannus may experience a range of symptoms, including:
- Blurred or decreased vision due to corneal opacity.
- Redness and irritation in the eye.
- Sensitivity to light (photophobia).
- Foreign body sensation in the eye.

Diagnosis

The diagnosis of corneal pannus typically involves:
- Clinical Examination: An ophthalmologist will perform a thorough eye examination, often using a slit lamp to visualize the cornea and assess the extent of the pannus.
- Medical History: Understanding the patient's history of eye conditions, trauma, or systemic diseases is crucial for accurate diagnosis.

Treatment

Management of corneal pannus may include:
- Medical Therapy: Anti-inflammatory medications, such as corticosteroids, may be prescribed to reduce inflammation and slow the progression of pannus.
- Surgical Intervention: In cases where vision is significantly impaired, surgical options such as corneal transplantation may be considered to restore clarity to the cornea.

Prognosis

The prognosis for individuals with corneal pannus varies depending on the underlying cause and the extent of the condition. Early diagnosis and appropriate management can lead to improved visual outcomes.

ICD-10-CM Code H16.42

The ICD-10-CM code H16.42 specifically denotes "Pannus (corneal)" without specifying laterality. However, there are additional codes for laterality:
- H16.421: Pannus (corneal), right eye.
- H16.422: Pannus (corneal), left eye.

These codes are essential for accurate medical billing and coding, ensuring that healthcare providers can document and report the condition appropriately for treatment and insurance purposes.

In summary, corneal pannus is a significant ocular condition that requires careful evaluation and management. Understanding its clinical presentation, causes, and treatment options is crucial for healthcare providers in delivering effective care to affected patients.
