ICD-10: H16.429

Clinical Description of ICD-10 Code H16.429: Pannus (Corneal), Unspecified Eye

Overview of Pannus
Pannus refers to a condition characterized by the growth of vascularized granulation tissue over the cornea, which can lead to visual impairment. This condition is often associated with chronic inflammation of the eye, particularly in cases of keratitis or other ocular surface diseases. The presence of pannus can indicate underlying issues such as autoimmune disorders, infections, or prolonged exposure to irritants.

ICD-10 Code H16.429
The ICD-10-CM code H16.429 specifically denotes "Pannus (corneal), unspecified eye." This classification is used when the pannus is present but the specific eye affected (right or left) is not specified. The code falls under the broader category of H16, which encompasses various forms of keratitis and corneal conditions.

Clinical Features

1. Symptoms:
   - Visual Disturbances: Patients may experience blurred vision or decreased visual acuity due to the obstruction of light entering the eye.
   - Discomfort: There may be associated symptoms such as redness, irritation, or a sensation of a foreign body in the eye.
