ICD-10 Code H21.5 – Other and unspecified adhesions and disruptions of iris and ciliary body (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H21.5 – Other and unspecified adhesions and disruptions of iris and ciliary body
What it is
This code identifies abnormal adhesions or disruptions involving the iris and ciliary body. It is used when the record describes a nontraumatic or unspecified condition affecting these anterior uveal structures.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal iris attachment, distortion of the pupil, or evidence of disruption involving the ciliary body on eye examination.
When to use this code
Use H21.5 when the provider documents other or unspecified adhesions or disruptions of the iris and ciliary body and no more specific diagnosis is stated. You should code from the ophthalmology note, operative report, or consultation note when these structures are directly identified.
If the chart only mentions an eye adhesion without specifying the iris or ciliary body, check documentation before assigning this code. Use the most specific code available if the record names a different ocular condition.
Do not use for
Do not use this code for traumatic eye injuries, corneal adhesions, or general intraocular inflammation unless the iris or ciliary body is specifically documented. Check documentation if the condition is better described by another ICD-10-CM code.
Coding tip
Confirm that the provider names the iris or ciliary body and uses “other” or “unspecified” before coding H21.5.
