Age-related cataract, morgagnian type, bilateral

This code signifies a bilateral age-related cataract that has progressed to the morgagnian type, characterized by a liquefied cortex and a freely movable nucleus within the lens capsule. This advanced form of cataract typically results in significant vision impairment.

Apply this code when documentation explicitly states bilateral morgagnian cataracts due to aging. This diagnosis is supported by ophthalmological examination findings detailing the advanced stage of cataract formation in both eyes, often including mention of a sunken or dislocated nucleus.

• Ensure documentation specifies "morgagnian type" and "bilateral" to accurately assign this code.
• Do not use this code for other types of age-related cataracts (e.g., cortical, nuclear, subcapsular) or cataracts of non-age-related etiology.
• Always review laterality carefully; separate codes exist for unilateral morgagnian cataracts.
