Peripheral Vestibular Disorders Secondary to Limitation of Extension of the Leg (Knee)
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Peripheral Vestibular Disorders when it develops after Limitation of Extension of the Leg (Knee).
Why Peripheral Vestibular Disorders Is Linked to Limitation of Extension of the Leg (Knee)
Straight leg limitations change walking posture.
Primary condition · VASRD 5261
Limitation of Extension of the Leg (Knee)
Knee extension limits your ability to fully straighten your leg. This diagnostic code covers a specific, measurable limitation: how far you're able to straighten the knee. Unlike general knee pain, this rating is driven almost entirely by a precise angle measurement, so how and when that measurement is taken can significantly affect the outcome.

Peripheral Vestibular Disorders
Peripheral vestibular disorders affect the inner ear structures responsible for balance, causing dizziness, vertigo, and sometimes nausea that can range from occasional to disabling. Common causes include ear infections, head trauma, or chronic noise exposure, which makes this a frequent secondary claim alongside hearing loss or tinnitus.
Peripheral Vestibular Disorders VA Rating Tiers
The VA rates Peripheral Vestibular Disorders the same way whether it's claimed directly or as secondary to Limitation of Extension of the Leg (Knee) — severity of Peripheral Vestibular Disorders itself determines the percentage.
Example combined rating
10% Limitation of Extension of the Leg (Knee) + 10% Peripheral Vestibular Disorders = 19%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 10% and 10% combine to 19%, not 20%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
Evidence for a Peripheral Vestibular Disorders Secondary Claim
- •A diagnosis from an ENT specialist or neurologist confirming a vestibular disorder.
- •Medical notes documenting how frequently vertigo or dizziness episodes occur.
