Can Peripheral Neuropathy, Lower Extremities be service-connected as secondary to Diabetes Mellitus?

It can be claimed that way. Under 38 CFR § 3.310, a condition that is proximately due to — or aggravated by — an already service-connected disability can itself be service-connected. Whether VA grants it depends on the evidence in your file, and the decision is made solely by VA adjudicators.

Do I need a nexus letter for a secondary claim?

In most cases yes. The rater needs a medical opinion connecting the two conditions at the "at least as likely as not" (50% or greater) standard. That opinion has to come from a licensed clinician who reviews your records and signs it — a draft is a starting point for that provider, not a substitute for their judgment.

Peripheral Neuropathy, Lower Extremities Secondary to Diabetes Mellitu

The medical link

Chronically elevated blood glucose directly damages the myelin sheath of peripheral nerves in the feet and legs, causing numbness, tingling, and pain.

What proves it

EMG/nerve conduction study; podiatry or neurology records; provider nexus linking neuropathy onset and distribution to diabetic end-organ damage.

The rule VA applies

38 CFR § 3.310 covers secondary service connection two ways: a condition caused by a service-connected disability, and one aggravated byit beyond its natural progression. Either route works, and a claim can argue both. The standard is “at least as likely as not” — a 50% probability, not proof beyond doubt.

You do not need to show peripheral neuropathy, lower extremities began during service. That is what makes a secondary claim different, and it is the step most veterans do not realise is available to them.
