Nexus Letter for Anxiety
Anxiety is commonly claimed secondary to a service-connected physical condition.
Anxiety claims follow the same structure as depression claims: either a direct claim supported by an in-service mental-health record, or — far more often — a secondary claim where a service-connected physical condition produced or worsened the anxiety. Because VA generally evaluates mental-health conditions under one rating, the practical goal is usually to establish the full picture rather than to stack separate awards.
Check this first: is anxiety presumptive for you?
If a presumption applies to your service, VA connects the condition without requiring you to prove the medical link — which can mean you do not need a nexus letter at all. Presumptions turn on where and when you served, so read the qualifying service line before assuming one fits.
- Former Prisoners of War
Applies to: Held as a POW for any length of time (conditions vary by duration — some require 30+ days).

Limits that change the answer
- !Former Prisoners of War: Duration-based conditions (30+ days POW) require evidence of captivity length in the POW status record.

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 anxiety letters must establish on top of that
- ›A current diagnosis from a provider VA recognizes for mental-health diagnoses.
- ›For a secondary claim: how the service-connected condition produces the anxiety, described for this patient.
- ›How the symptoms affect work and daily functioning, since that is what the evaluation criteria measure.
Most common secondary pathways for anxiety
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 anxiety is most often claimed behind:
- ›A serious or disabling service-connected physical condition
- ›Chronic pain
- ›Tinnitus
The primary has to already be service-connected. If it is not, that claim comes first.
What gets anxiety letters discounted
- !If PTSD is already service-connected, a separate anxiety rating is generally not available — the conditions are evaluated together.
- !Occupational impact is the core of the rating criteria and is the part most letters underdescribe.
