ICD-10: H11.04

Peripheral pterygium of the eye, classified under ICD-10 code H11.04, is characterized by a few distinct clinical presentations, signs, symptoms, and patient characteristics:

Clinical Presentation

• Definition: Peripheral pterygium is a benign growth of fibrovascular tissue that extends from the conjunctiva onto the cornea. The stationary type indicates that the growth is not progressing or changing significantly over time [1].

Signs

• Appearance: The pterygium typically presents as a triangular or wing-shaped growth on the conjunctiva, which may encroach upon the cornea. It is often reddish in color due to vascularization [1].
• Location: It usually occurs on the nasal or temporal side of the eye, with the nasal side being more common [1].

Symptoms

• Visual Disturbances: Patients may experience blurred vision if the pterygium encroaches significantly onto the cornea [1].
• Irritation: Common symptoms include a sensation of dryness, irritation, or a foreign body feeling in the eye [1].
• Redness: The affected eye may appear red or inflamed, particularly if the pterygium is irritated [1].

Patient Characteristics

• Demographics: Peripheral pterygium is more prevalent in individuals who are frequently exposed to UV light, such as outdoor workers. It is commonly seen in middle-aged adults but can occur in younger individuals as well [1].
• Risk Factors: Factors such as prolonged sun exposure, dry and windy environments, and certain genetic predispositions may increase the likelihood of developing a pterygium [1].

In summary, peripheral pterygium of the eye (stationary) is a benign ocular condition that can lead to discomfort and visual disturbances, particularly in individuals with significant UV exposure. Regular monitoring and management may be necessary to address symptoms and prevent progression.

The ICD-10 code H11.04 refers specifically to "Peripheral pterygium of eye, stationary." Here are some alternative names and related terms associated with this code:

• H11.041: Peripheral pterygium, stationary, right eye
• H11.042: Peripheral pterygium, stationary, left eye
• H11.043: Peripheral pterygium, stationary, bilateral
• H11.049: Peripheral pterygium, stationary, unspecified eye

Additionally, the broader category includes other types of pterygium, such as:

• H11.00: Unspecified pterygium of eye
• H11.01: Amyloid pterygium
• H11.02: Central pterygium of eye
• H11.03: Double pterygium of eye

These classifications help in identifying the specific type and location of the pterygium, which is a growth of tissue on the eye's surface.
