ICD-10 Code E10.351 – Type 1 diabetes mellitus with proliferative diabetic retinopathy with macular edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.351 – Type 1 diabetes mellitus with proliferative diabetic retinopathy with macular edema
What it is
This code identifies type 1 diabetes with proliferative diabetic retinopathy and macular edema. It means the diabetic eye disease has progressed to abnormal retinal vessel growth and swelling in the macula.
Clinical signs
Findings may include neovascularization, retinal hemorrhage, and macular thickening or edema on eye examination. Vision may be blurred or reduced, but clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents type 1 diabetes with proliferative diabetic retinopathy and macular edema in the same eye or both eyes. It also applies when ophthalmology or endocrinology notes clearly support both the proliferative stage and macular edema. If the record does not specify these elements, check documentation before coding.
Do not use for
Do not use this code for nonproliferative diabetic retinopathy, diabetic macular edema without proliferative disease, or retinopathy due to another cause. Do not assume laterality or severity that is not documented.
Coding tip
Confirm that both proliferative retinopathy and macular edema are documented before assigning E10.351.
