December 7, 2025
5 views

OIF Army veteran • Chronic tinnitus • Episodic vertigo and imbalance

The Challenge

The veteran’s vertigo claim was previously denied. VA stated: “The evidence does not show your vertigo is proximately due to or the result of your service-connected tinnitus. No medical relationship has been established.”

What Existed Before

  • Service-connected tinnitus.
  • Episodes of dizziness and imbalance

Our Contribution

  • Review of auditory and balance-related patterns documented in treatment notes
  • Identification of symptom timing consistent with secondary vestibular involvement
  • Chronological analysis comparing tinnitus onset with vertigo development
  • Structured secondary-service-connection explanation using existing evidence

Key Takeaway

After the secondary-connection documentation - NEXUS LETTER was submitted, the veteran later received a favorable VA decision granting vertigo secondary to tinnitus.
