ICD-10 Code H26.121 – Partially resolved traumatic cataract, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.121 – Partially resolved traumatic cataract, right eye
What it is
This code identifies a traumatic cataract in the right eye that has partially improved but is not fully resolved. Use it when the lens opacity is still present after an eye injury.
Clinical signs
Findings may include decreased vision, lens opacity, or a history of ocular trauma affecting the right eye. Clinical features vary; refer to documentation.
When to use this code
Use H26.121 when the provider documents a partially resolved traumatic cataract specifically in the right eye. It fits follow-up visits after trauma when the cataract remains present but is improving. Confirm laterality and that the cause is traumatic, not age-related or congenital.
Do not use for
Do not use this code for traumatic cataract in the left eye, both eyes, or unspecified eye. Do not use it for nontraumatic cataracts or when documentation does not confirm partial resolution.
Coding tip
Always verify the eye side and the traumatic cause in the note before assigning H26.121.
