ICD-10 Code H33.05 – Total retinal detachment (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H33.05 – Total retinal detachment
What it is
Total retinal detachment means the entire retina has separated from the underlying tissue in the eye. Use this code when the documentation clearly states a complete detachment rather than a partial or localized one.
Clinical signs
Common findings include sudden vision loss, flashes, floaters, or a curtain-like shadow across vision. Clinical features vary; refer to documentation and the ophthalmology report for confirmation of total involvement.
When to use this code
Use H33.05 when the provider documents total retinal detachment, or when the operative or specialist note confirms complete retinal separation. This code fits confirmed diagnoses in either acute or chronic settings if the record does not specify a different type.
If the chart only says retinal detachment without extent, check documentation before assigning this code. Do not guess total involvement from symptoms alone.
Do not use for
Do not use this code for partial, localized, or unspecified retinal detachment. Check documentation if the note describes a retinal tear, detachment risk, or another vitreoretinal disorder instead.
Coding tip
Always look for the word “total” or equivalent wording in the ophthalmology documentation before coding H33.05.
