[DATE]

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 Sleep Apnea, confirmed by
[EXAM FINDING, TEST, OR IMAGING] on [DATE].

OPINION

It is my medical opinion that [VETERAN NAME]'s Sleep Apnea 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 sleep apnea letters must establish on top of that

• ›A current diagnosis confirmed by a sleep study (polysomnography). VA will not rate obstructive sleep apnea on symptoms alone — without the study there is nothing for the letter to attach to.
• ›Which already-service-connected condition is doing the causing or the worsening, named specifically, with the mechanism spelled out — not "is related to his service-connected conditions."
• ›If the theory is aggravation rather than causation, say so in those words and cite 38 CFR § 3.310(b). Aggravation is a separate, fully compensable pathway and raters do not infer it.

What gets sleep apnea letters discounted

• !A letter that says sleep apnea is "common among veterans" states an epidemiological fact and no opinion about you. The Board reads that as no nexus at all.
• !Never having been diagnosed in service is not a weakness in a secondary claim — it is expected. Do not let the letter apologize for it or strain to find an in-service onset that is not in the records.
• !If a CPAP was prescribed, that fact belongs in the letter, because the rating level for sleep apnea turns on whether breathing assistance is required.
