ICD-10 Code H31.31 – Expulsive choroidal hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.31 – Expulsive choroidal hemorrhage
What it is
H31.31 identifies an expulsive choroidal hemorrhage, a severe bleeding event in the choroid of the eye. It is a rare, vision-threatening complication that usually occurs around eye surgery or major ocular trauma.
Clinical signs
Typical findings include sudden ocular pain, marked loss of vision, a shallow or collapsed anterior chamber, and abrupt increase in intraocular pressure changes. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents expulsive choroidal hemorrhage or an equivalent term such as massive choroidal bleeding with expulsive features. It may be reported after intraocular surgery or trauma when the hemorrhage is the confirmed diagnosis. Check documentation if the note only describes postoperative bleeding without specifying choroidal involvement.
Do not use for
Do not use this code for minor subconjunctival hemorrhage, routine postoperative bruising, or unspecified intraocular bleeding. If the record does not clearly identify an expulsive choroidal hemorrhage, check documentation.
Coding tip
Code the condition only when the record clearly ties the hemorrhage to the choroid and indicates expulsive severity.
