When a rating decision says your condition is "not service connected" but acknowledges you currently have the diagnosed condition, it usually means the VA found two of the three required elements for service connection: (1) a current diagnosis, and either (2) an in-service event, injury, or illness, or (3) a doctor's opinion linking the two — but not the crucial third piece, the medical nexus. Under 38 CFR 3.303, service connection requires evidence of a current disability, an in-service incurrence or aggravation, and a medical link (nexus) between the two. If the decision letter specifically cites a lack of nexus evidence, your file is missing a doctor's statement connecting the current back condition to something that happened, or was aggravated, during service.
A nexus letter is a written medical opinion, ideally from a treating physician or a private specialist familiar with your records, stating that your current condition is "at least as likely as not" (50% or greater probability) related to a specific in-service event, injury, exposure, or another already-service-connected condition. Vague statements like "could be related" are usually insufficient; the letter should explain the medical reasoning, reference your service treatment records or lay statements about onset, and use the correct probability language.

If it is new and relevant evidence, you can file a Supplemental Claim (VA Form 20-0995), which allows VA to review the case with the added nexus opinion. If you believe VA made a legal or factual error in weighing the evidence already in file, a Higher-Level Review (VA Form 20-0996) may be more appropriate, though that route does not allow new evidence. You can also request a Board appeal (VA Form 10182) if you want a Veterans Law Judge to review it, with or without a hearing.
Among appealed service-connection decisions in VetAid's library of 39,855 appealed VA decisions, about half of those with a recorded outcome were vacated or remanded, roughly 30% were affirmed, and about 7% were reversed or granted outright — figures that describe appellate outcomes for cases that were already appealed, not the odds of winning an initial claim, and appealed cases are not a random sample of all claims.
The concrete next step is to obtain a detailed nexus opinion addressing the specific in-service event and the "at least as likely as not" standard, then file it as new evidence with a Supplemental Claim (VA Form 20-0995).
