Ogiso Health provides physician-led evaluation and support services for veterans in Nashville, Tennessee. Led by Dr. Olatunde Oso, a Board-Certified Preventive and Occupational Medicine physician, we offer objective, thorough medical evaluations to help veterans navigate VA claims, disability determinations, and return-to-work decisions.
We offer a range of evaluation services relevant to veterans, including:
A nexus letter is a physician-authored document that establishes the link — or "nexus" — between a veteran's current medical condition and their military service. The VA requires this documentation when the connection between service and a disability is not immediately obvious from service records alone. A well-written nexus letter from a qualified physician can significantly strengthen a VA disability claim. Dr. Oso reviews the veteran's service history, medical records, and current condition to provide a thorough, defensible medical opinion.
An IME is a medical evaluation conducted by a physician who has no prior treating relationship with the patient, providing an objective opinion on diagnosis, causation, and functional limitations. For veterans, an IME may be used to support or contest a VA rating decision, provide documentation for legal proceedings, or satisfy employer or insurance requirements for disability claims.
Yes. If a veteran believes their VA disability rating does not accurately reflect their condition, a physician's independent evaluation and written opinion can provide supporting evidence for an appeal or higher-level review. Dr. Oso can review existing medical records, conduct a current examination, and provide a written assessment that addresses the specific conditions under appeal.
Evaluation and IME services are typically provided on a cash-pay or direct-pay basis, which ensures the physician's opinion remains independent and objective. Some services may be billable depending on the purpose of the evaluation. Contact our office to discuss your specific situation and payment options.
Scheduling is straightforward and does not require a physician referral. Contact us directly to discuss your needs before booking so we can ensure the correct evaluation type is scheduled. Call us at 615-397-6243 or use our online scheduling system.
We are located at 2700 Gallatin Pike, Suite D, Nashville, TN 37216. We serve veterans throughout Middle Tennessee including Nashville, Murfreesboro, Clarksville, Franklin, and Brentwood.
Occupational medicine physicians are specifically trained in the relationship between physical and environmental exposures and health outcomes — making this specialty particularly well-suited for evaluating service-connected conditions. Dr. Oso's training in both Preventive and Occupational Medicine means he understands not just the diagnosis, but how service-related exposures, demands, and injuries translate into functional limitations and long-term health risk.
