Nexus Letter for GERD
GERD is most often claimed secondary to a mental-health condition or to medication taken for one.
GERD claims are usually secondary claims, and they come in two flavors that a good letter distinguishes. One is the direct physiological route, where a service-connected mental-health condition drives the reflux. The other is the medication route, where the drugs prescribed for a service-connected condition — NSAIDs for chronic pain being the common example — cause or worsen the reflux. Both are valid under 38 CFR § 3.310, but they call for different rationales.
What every nexus letter must do
These four apply to every condition. A letter missing any one of them is the most common reason an otherwise good claim is denied.
- 1.A statement that your records were reviewed
VA weighs a medical opinion partly on whether the clinician actually had the evidence in front of them. A letter that does not say what was reviewed reads as an opinion formed without the file.
- 2.A current diagnosis
Service connection requires a present disability. The letter should state the diagnosis plainly rather than describing symptoms and leaving the conclusion implied.
- 3.The phrase "at least as likely as not"
This is VA's evidentiary standard — a 50 percent or greater probability. Under 38 CFR § 3.102 the tie goes to the veteran, and this phrase is what places the opinion at or above that line. Softer wording ("possibly," "may be," "could be," "cannot rule out") sits below the standard and is a leading cause of denial.
- 4.A stated medical rationale
The reasoning behind the conclusion, not just the conclusion. An opinion that gives an answer without explaining the basis for it carries little weight, no matter how well-credentialed the signer.
What GERD letters must establish on top of that
- ›Which secondary route applies: the condition itself, or the medication prescribed for it.
- ›If the medication route: the specific drug, that it was prescribed for a service-connected condition, and the known gastrointestinal effect.
- ›Symptom frequency and severity, since GERD is evaluated on the symptom picture rather than on the diagnosis alone.
Most common secondary pathways for GERD
Under 38 CFR § 3.310, a condition caused or permanently worsened by an already-service-connected condition is itself service-connected. These are the primaries GERD is most often claimed behind:
- ›PTSD, depression, or anxiety
- ›NSAIDs or other medication prescribed for a service-connected condition
- ›Sleep apnea
The primary has to already be service-connected. If it is not, that claim comes first.
What gets GERD letters discounted
- !The medication pathway is routinely missed by veterans and by the doctors writing for them. If a service-connected condition is being treated with something that causes reflux, that is a claim.
- !Over-the-counter self-treatment often means there is no paper trail. The letter is stronger when it captures the history the records do not show.
