Usually Secondary service connection38 CFR § 3.310

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.

Re: [VETERAN FULL NAME]
    VA File Number / SSN: [NUMBER]
    Date of Birth: [DATE OF BIRTH]

To Whom It May Concern:

I am [PROVIDER NAME], [DEGREE], licensed to practice in [STATE],
license number [NUMBER]. I have treated [VETERAN NAME] since [DATE].
[Or: I evaluated [VETERAN NAME] on [DATE].]

RECORDS REVIEWED

In forming the opinion below, I reviewed the following: [service
treatment records; DD-214; VA treatment records dated [RANGE];
private treatment records from [PROVIDER]; [IMAGING OR TEST] dated
[DATE]; and the veteran's own account of [EVENT]].

DIAGNOSIS

[VETERAN NAME] has a current diagnosis of GERD, confirmed by
[EXAM FINDING, TEST, OR IMAGING] on [DATE].

OPINION

It is my medical opinion that [VETERAN NAME]'s GERD is
at least as likely as not [caused by / incurred during /
aggravated beyond its natural progression by]
[the veteran's service-connected [PRIMARY CONDITION]].

RATIONALE

[Two to four sentences giving the medical reasoning. Name the
mechanism connecting the two. Point to what in the records supports
it — onset timing, continuity of symptoms since service, findings on
examination. Address the most obvious alternative explanation and say
why it does not account for this presentation.]

I am available to provide further information or clarification if
that would assist in adjudicating this claim.

Sincerely,

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. 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. 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. 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. 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.
