ICD-10 Code H35.05 – Retinal Neovascularization, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.05 – Retinal neovascularization, unspecified
What it is
H35.05 identifies abnormal new blood vessel growth in the retina when the specific cause or subtype is not documented. Use it for retinal neovascularization described without further detail.
Clinical signs
Clinical features vary; refer to documentation. Findings may include retinal new vessels seen on exam or imaging, with possible associated hemorrhage, ischemia, or tractional change.
When to use this code
Use this code when the provider documents retinal neovascularization but does not specify the underlying condition or location. It may apply to charted retinal vascular proliferation, neovascular changes, or “new vessels in the retina” without further detail.
If the record identifies a cause such as diabetic retinopathy or retinal vein occlusion, code the documented condition instead or in addition, as appropriate. Check documentation for laterality and any more specific retinal diagnosis.
Do not use for
Do not use H35.05 for neovascularization clearly linked to another diagnosed eye disorder when that condition is documented. Do not use it if the record describes choroidal or iris neovascularization instead.
Coding tip
Query for the underlying retinal disease and specificity before assigning H35.05, because a more precise code may be available.
