ICD-10 Code H33.03 – Retinal detachment with giant retinal tear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.03 – Retinal detachment with giant retinal tear
What it is
H33.03 identifies a retinal detachment caused by a giant retinal tear, a large full-thickness break in the retina. The code describes the detachment and its specific tear-related cause.
Clinical signs
Typical findings include sudden flashes, floaters, a curtain-like visual field loss, or reduced vision. Clinical features vary; refer to documentation and ophthalmic examination findings.
When to use this code
Use this code when the provider documents retinal detachment specifically due to a giant retinal tear. It fits operative, consultation, or ophthalmology notes that clearly link the detachment to the tear. Check documentation if the tear type is not stated.
Do not use for
Do not use this code for retinal detachment without a giant retinal tear, or for retinal tears that have not caused detachment. If the record is unclear, check documentation.
Coding tip
Look for explicit wording such as “giant retinal tear” and “retinal detachment” in the same record before assigning H33.03.
