ICD-10 Code H35.70 – Unspecified separation of retinal layers (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.70 – Unspecified separation of retinal layers
What it is
This code identifies separation of the retinal layers without a more specific description. Use it when the record confirms retinal layer separation but does not specify the type or cause.
Clinical signs
Clinical features vary; refer to documentation. Patients may have visual disturbance, reduced central vision, flashes, floaters, or a reported retinal abnormality on ophthalmic examination or imaging.
When to use this code
Use H35.70 when the provider documents unspecified separation of retinal layers and no more detailed retinal diagnosis is recorded. It is appropriate when the chart lacks clarification about the exact retinal layer involved or the underlying condition.
If later documentation identifies a more specific retinal disorder, code that diagnosis instead. Check documentation carefully so you do not default to this code when the record supports a more precise option.
Do not use for
Do not use this code for retinal detachment, retinoschisis, or other specifically documented retinal diseases. If the condition is described more precisely, choose the exact code instead of an unspecified code.
Coding tip
Query the provider when the note says “retinal separation” but does not clarify the diagnosis, because specificity may change the code selection.
