2025 ICD-10-CM code H35.33

Angioid streaks of macula.

The ICD-10-CM guidelines specify using an external cause code following H35.33 if the condition is due to an external cause, such as trauma.

Medical necessity for services related to H35.33 hinges on the presence of visual symptoms or the risk of complications. Interventions like laser photocoagulation or anti-VEGF injections may be medically necessary if vision loss or choroidal neovascularization occurs.

Diagnosis and management of angioid streaks of the macula fall under the purview of ophthalmologists.They conduct comprehensive eye exams, including imaging studies like optical coherence tomography (OCT) and fluorescein angiography, to evaluate the condition and determine appropriate treatment strategies.

In simple words: This code signifies the presence of angioid streaks, which are cracks in Bruch's membrane, a layer of tissue beneath the retina in the back of the eye. These streaks typically appear in the macula, the central part of the retina responsible for sharp, detailed vision.

Angioid streaks of macula

Example 1: A 55-year-old patient presents with complaints of distorted central vision. Upon examination, angioid streaks are observed in the macula of both eyes, leading to a diagnosis of H35.33., A patient with a history of pseudoxanthoma elasticum develops angioid streaks in the macula, coded as H35.33. Regular monitoring is recommended to manage potential complications., During a routine eye exam, a patient is found to have angioid streaks affecting the macula. While asymptomatic currently, the patient is advised about potential vision changes and scheduled for follow-up.

Documentation for H35.33 should include detailed ophthalmological findings, including the location and extent of angioid streaks, associated visual symptoms, and any underlying systemic conditions. Diagnostic imaging reports, such as OCT and fluorescein angiography, are crucial for confirming the diagnosis and guiding treatment.

** Angioid streaks are often associated with systemic conditions like Ehlers-Danlos syndrome, pseudoxanthoma elasticum, and Paget's disease. It's important to evaluate patients with H35.33 for these conditions to ensure comprehensive care.
