Common Questions About Nexus Letters

A nexus letter is a medical opinion written by a licensed healthcare provider that establishes a connection between a veteran's current medical condition and their military service. The VA requires three elements for service connection: a current diagnosis, evidence of an in-service event or injury, and a medical link between the two. A nexus letter addresses that third requirement by providing professional medical reasoning that supports the service connection.

All nexus letters are authored and signed by licensed Medical Doctors (MDs). Our team also includes Physician Assistants (PAs) and Licensed Clinical Psychologists who collaborate on complex cases. Many of our providers have military backgrounds and understand the unique medical experiences of veterans.

Our standard turnaround is 7 business days or less from the date we receive complete medical and service records. For organizations processing high volumes, we can discuss expedited timelines during your consultation.

Yes. A well-written nexus letter is often the most impactful piece of new evidence a veteran can submit with a supplemental claim or appeal after a denial. Many denials occur because the original claim lacked a clear medical opinion connecting the condition to service. Our nexus letters address the specific deficiency by providing a detailed medical rationale that meets VA adjudication standards.

Absolutely. Our primary focus is B2B partnerships with VA disability firms, claims assistance organizations, accredited agents, and attorneys. We provide scalable medical documentation services including nexus letters and psychological evaluations that integrate into your existing case management workflow.

We provide nexus letters for a wide range of physical and mental health conditions, including PTSD, traumatic brain injury (TBI), tinnitus, hearing loss, musculoskeletal injuries, sleep apnea, migraines, back and neck conditions, knee injuries, secondary conditions like depression or anxiety linked to a service-connected disability, and conditions related to toxic exposures covered under the PACT Act.

This is the company you need to solve your VA disability claim! I have known these members for a long time and worked exclusively in the military health system and in the civilian sector and they time and time again exude nothing but excellence with only the patient's best interest in mind. There are no gimmicks. There are no ulterior motives. Just simply overwhelming efforts, beyond what many other companies would be willing to provide. Semper Solutus is dedicated to meeting your needs. These people care about you and will fight to find you a solution!

I was able to get in contact with Matthew Wilyonson through a co worker. He was very informative and answered any question I had. He put together a game plan and presented it to me. He is very professional and knowledgeable in the VA department. His communication is great and any time I have a question he responds.

Dr Wilyonson is amazing. I was in the Navy with him and he has always been tireless and service oriented. His energy seem to peak when things get tough. Have never seen a problem he could not tackle and solve. So fortunate to have him address my VA Claim. A God sent, doing the work of a brilliant servant. Can not recommend and higher.

I can't recommend Semper Solutus enough. I worked with them during my VA disability process, and the level of guidance, attention to detail, and overall support made a major difference in my outcome. What stood out to me most was how thorough and honest the process was. Nothing felt rushed or generic. Every part of my case was handled with intention, and I always felt like my situation was actually being understood instead of just processed. Communication was consistent, and I never felt left in the dark. If I had questions, Doc Wilyonson answered them clearly and without the runaround. That alone is rare. Truly great people working to serve us, the veteran community.
