Posterior subcapsular polar age-related cataract, unsp eye

This code signifies a specific type of age-related cataract characterized by opacities located at the posterior pole of the lens, just beneath the lens capsule. This subcapsular location often leads to significant visual impairment, particularly with glare and in bright light conditions.

Apply this code when documentation explicitly states "posterior subcapsular polar cataract" or "PSC polar cataract" and specifies it as age-related, without laterality. This diagnosis is typically made during an ophthalmic examination, often with a slit lamp.

• Ensure the documentation clearly indicates the "polar" characteristic, not just general posterior subcapsular.
• Avoid using this code if the cataract is congenital, traumatic, or secondary to another condition (e.g., diabetes, steroid use).
• If laterality (right or left eye) is documented, use the more specific codes H25.041 or H25.042.
