Sciatic Radiculopathy Claimed Secondary to Type 2 Diabetes
Sciatic Radiculopathy (VA diagnostic code 8520) is sometimes claimed as secondary to service-connected Type 2 Diabetes (code 7913) under 38 CFR 3.310. This page reports what published Board of Veterans' Appeals decisions on that pairing show. It is an encyclopedic reference, not a forecast.
What published Board decisions show
Across 5,968 published Board (BVA) decisions in our index where sciatic radiculopathy was claimed as secondary to type 2 diabetes, the outcomes broke down as follows. These are historical aggregates of decided appeals, not a prediction for any individual claim.
Counting only appeals that were granted or denied (setting aside remands), about 54% were granted. A remand is not a loss; it means the Board needed more evidence before deciding.

How this pairing works
A secondary claim says sciatic radiculopathy flows from a service-connected type 2 diabetes. Whether the medical link exists in any one case is a medical question decided on that case's own evidence (the nexus). See the Secondary Claim guide.
What a secondary claim on this pairing needs
Under 38 CFR 3.310 a secondary claim turns on three elements:
- A current diagnosis: a medical diagnosis of sciatic radiculopathy (the secondary).
- A service-connected primary: Type 2 Diabetes, already service-connected (the primary). A 0% primary still counts.
- A medical nexus: a medical opinion linking the sciatic radiculopathy to the type 2 diabetes, showing the primary caused or aggravated it.
See the Secondary Claim guide for the caused-versus-aggravated split, and the Nexus Letter guide for what makes the medical opinion strong.
Frequently Asked Questions
Does Type 2 Diabetes have to be highly rated to support a sciatic radiculopathy secondary claim?
No. 38 CFR 3.310 looks at whether the service-connected Type 2 Diabetes caused or aggravated the sciatic radiculopathy, not at how severe the Type 2 Diabetes rating is. Even a 0% service-connected primary can anchor a secondary claim.
What do the percentages on this page mean?
