ICD-10 Code H31.321 – Choroidal rupture, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.321 – Choroidal rupture, right eye
What it is
H31.321 identifies a tear in the choroid of the right eye, usually caused by blunt trauma. It documents a specific posterior segment injury rather than a general eye contusion.
Clinical signs
Typical findings include a traumatic choroidal break seen on eye examination, often with decreased vision or visual distortion. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents choroidal rupture in the right eye, including after blunt ocular trauma. It is appropriate when the record clearly identifies the right eye and the injury is current or being evaluated. Check documentation if laterality is unclear.
Do not use for
Do not use it for unspecified eye laterality or for other retinal, choroidal, or globe injuries without documented choroidal rupture. Do not guess the eye involved.
Coding tip
Verify laterality and trauma history in the note before assigning H31.321.
