ICD-10 Code H21.223 – Degeneration of ciliary body, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H21.223 – Degeneration of ciliary body, bilateral
What it is
H21.223 identifies degeneration affecting both ciliary bodies, the eye structures that help control lens shape and produce aqueous fluid. Use it when documentation specifically states bilateral ciliary body degeneration.
Clinical signs
Clinical features vary; refer to documentation. Findings may include documented structural or degenerative changes of the ciliary body on eye examination or imaging, with bilateral involvement clearly stated.
When to use this code
Use this code when the clinician documents degeneration of the ciliary body in both eyes and no more specific diagnosis is provided. It may also apply when the record describes bilateral ciliary body degeneration without another dominant eye disorder explaining the finding. If laterality is not stated, check documentation before coding.
Do not use for
Do not use this code for unilateral ciliary body degeneration or for nonspecific anterior segment disease. If the note describes another condition, such as inflammation, trauma, or a different ocular disorder, code the documented diagnosis instead.
Coding tip
Confirm that “bilateral” is explicitly documented; otherwise, do not assume H21.223.
