2026 ICD-10-CM Diagnosis Code H25.21 – Age-related cataract, morgagnian type, right eye
What it is
This code identifies an age-related cataract in the right eye with a morgagnian type lens change. It indicates advanced lens opacity with a liquefied cortex and denser nucleus.
Clinical signs
Typical findings include reduced visual acuity, glare, and lens opacity on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H25.21 when the clinician documents a morgagnian type age-related cataract specifically in the right eye. Code it from ophthalmology notes, exam findings, or operative documentation that clearly identifies laterality and cataract type.
Do not use for
Do not use this code for cataracts in the left eye, both eyes, or unspecified eye. Do not use it when the record does not confirm an age-related morgagnian type cataract; check documentation.
Coding tip
Verify both laterality and cataract subtype before assigning H25.21.
