A back nexus letter for your VA claim: lumbar spine conditions, from your records

What the clinician looks for in your back records

Lower back claims often have plenty of pain on paper and too little diagnosis. For the flat $500, the clinician reviews your records for a named lumbar condition and the in-service history behind it, then writes the reasoning that joins them.

• A diagnosis of the lumbar spine by name: lumbosacral strain, degenerative disc disease, a herniated or bulging disc, spinal stenosis, spondylolisthesis, or arthritis of the spine.
• Imaging, such as X-rays or an MRI of the lumbar spine, with the findings and dates in the report.
• Range-of-motion measurements, especially how far you can bend forward, and notes on muscle spasm, guarding, or an abnormal walk or spinal curve.
• Any periods of bed rest prescribed by a treating provider for disc episodes, since VA rates disc disease partly on those.
• In-service back injuries and strain: lifting injuries, falls, vehicle accidents, hard parachute landings, carrying heavy loads, and the profiles or physical therapy that followed.
• Pain, numbness or tingling running down a leg, which may be a separate nerve diagnosis worth its own claim.

Common service-connection routes for a back condition

Direct service connection under 38 CFR 3.303 is the usual route: an in-service injury or years of heavy physical work, documented in your service records, and a lumbar diagnosis today that a clinician can tie to it. Continued complaints after discharge help show the connection did not break.

Secondary service connection under 38 CFR 3.310 may fit when a service-connected knee, ankle, foot or hip condition changed your gait, or left one leg functionally shorter, for long enough to strain the lower back. A clinician may consider that route when your records document the altered gait or the leg length difference over time.

A back condition is also a common starting point for other claims. Sciatica from a lumbar disc, for example, is usually claimed secondary to the back and rated separately; the radiculopathy page covers that opinion.

Is there a DBQ for a back condition?

Yes. VA's public Back (Thoracolumbar Spine) DBQ covers the lower and middle back. Commander Health completes it for a flat $200 from your existing records, or for $550 together with the nexus letter. The licensed clinician completes and signs it only when the records hold recent forward-bending and other range-of-motion measurements and the flare-up details the form asks about.

The same DBQ includes questions about nerve symptoms in the legs, so a well-documented sciatica history belongs in the upload. VA can still order its own exam and decides the rating.

What it is not

• Physical conditions only: Commander Health does not write PTSD or other mental health opinions, or secondary opinions that run through a mental health condition.
• Not an exam or an appointment. There are no calls or video visits; the clinician works from your records, and any follow-up comes by email.
• Not a filing service. Commander Health does not file claims and is not a VSO, a law firm, or a VA-accredited representative. Free help filing a claim is available from a VA-accredited Veterans Service Organization.
• Not a guarantee. Clinical review never guarantees an outcome. A clinician signs only if your records support the opinion, and VA decides the claim.

Frequently asked questions

I strained my back in service and it got better. Does that still count?

It can, if your records show the problem came back or never fully went away, and a clinician finds today's lumbar diagnosis is at least as likely as not tied to it. A single strain with no later complaints is a harder case, and the screen tells you what is missing.

My X-ray was normal. Is a back claim still possible?

X-rays show bone, not discs, muscles or nerves. A diagnosis can rest on an MRI or on clinical findings, and the clinician reads the whole record, not one image.

Is sciatica part of my back claim?

It is usually a separate diagnosis, claimed secondary to the back and rated on its own. Commander Health has a separate radiculopathy page covering what that opinion needs.

Can my back be connected to my service-connected knee?

A clinician may consider it under 38 CFR 3.310 when your records show the knee changed how you walk over a long period. The clinician signs the $500 letter only if your records and the medical literature support it.
