ICD-10 Code H31.303 – Unspecified choroidal hemorrhage, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.303 – Unspecified choroidal hemorrhage, bilateral
What it is
This code identifies bleeding in the choroid of both eyes when the documentation does not specify the cause or type. Use it for bilateral choroidal hemorrhage that is described as unspecified.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include sudden visual disturbance, ocular pain, or signs of intraocular bleeding noted on eye examination.
When to use this code
Use H31.303 when the provider documents bilateral choroidal hemorrhage and does not identify a more specific etiology or subtype. It fits ophthalmology notes, imaging reports, or consults that confirm hemorrhage in both choroids. If laterality or cause is documented more precisely, check documentation before assigning this code.
Do not use for
Do not use this code for hemorrhage limited to one eye or for other retinal, vitreous, or subconjunctival bleeding. Also avoid it when the record specifies a different choroidal disorder or a more detailed hemorrhage code.
Coding tip
Confirm bilateral involvement and the word “unspecified” in the note before selecting H31.303.
