Hypertension Secondary to PTSD: How to Claim It

If you have a service-connected mental health condition like PTSD and you have also developed high blood pressure, you may be able to claim that hypertension as a secondary service-connected condition — and add it to your overall rating. The medical link between chronic stress and cardiovascular problems is well recognized, which makes this one of the more winnable secondary claims when it is documented correctly. Here is how it works.

What “secondary service connection” means

Secondary service connection is when a condition is caused or aggravated by a condition the VA has already service-connected. You do not have to tie the new condition directly to an event in service — you tie it to your existing service-connected disability. If your PTSD is service-connected and it caused or worsened your high blood pressure, the hypertension can ride in as secondary. Our overview of secondary conditions explains the broader concept and lists conditions that commonly qualify.

Is hypertension secondary to PTSD recognized?

Yes. There is substantial medical literature connecting chronic PTSD — with its sustained stress response, disrupted sleep, and elevated stress hormones — to the development and worsening of hypertension. The VA does not treat this as automatic or “presumptive,” so you still have to prove it in your specific case, but the underlying medical relationship is accepted enough that a well-supported claim has a real path to approval. The key is evidence, not the plausibility of the theory.

The evidence you need

A secondary claim has three parts: a current diagnosis of hypertension (blood-pressure readings and a doctor’s diagnosis), an already service-connected primary condition (your PTSD), and a medical nexus opinion connecting the two. The nexus is the piece that wins or loses these claims. A nexus letter from a physician or psychologist stating that your PTSD “at least as likely as not” caused or aggravated your hypertension — with a short rationale referencing your records and the medical literature — is what the rater needs to grant the claim.

How the VA rates hypertension

Hypertension is rated on your diastolic and systolic numbers and whether you require continuous medication to control it. Ratings generally start at the lower levels for readings that are elevated or that require medication, and climb as the diastolic and systolic pressures rise. Importantly, even a lower rating still combines with your other ratings to raise your overall percentage — see how combined ratings math works, because adding a secondary condition can push your combined rating to the next bracket. Confirm the current rating criteria at VA.gov, since the schedule is periodically updated.

Building the claim step by step

Start by confirming your PTSD is already service-connected. Get your blood pressure formally diagnosed and documented, ideally with multiple readings over time, and note whether you are on medication. Then obtain a nexus opinion that explicitly links the hypertension to your PTSD. File the hypertension as a secondary claim, clearly identifying PTSD as the primary condition. Attach the nexus letter and any relevant medical records. If you are early in the process, our guide on how to apply for VA disability walks through filing.

The nexus letter is everything

Because hypertension has many possible causes (age, weight, diet, family history), the VA examiner may attribute it to something other than your PTSD. A strong nexus letter heads this off by acknowledging other risk factors and still concluding that PTSD is at least a significant contributing cause or aggravator. The more your provider ties the opinion to your actual treatment history — sleep disruption, stress symptoms, the timeline of your blood pressure rising — the harder it is to dismiss.

The C&P exam

You may be scheduled for a C&P exam for the hypertension and possibly a review of your PTSD. Be candid about your symptoms, your stress levels, your sleep, and how long you have been on blood-pressure medication. Do not minimize the connection or imply your blood pressure is “just from getting older.” Our guide on what not to say at a C&P exam helps you prepare so an off-hand comment does not undercut a legitimate claim.

Common mistakes to avoid

The biggest mistake is filing the secondary claim with no nexus opinion and hoping the VA connects the dots — it usually will not. Other mistakes include not clearly labeling the claim as secondary to PTSD, failing to document that you are on continuous medication, and giving up after a single denial. If you are denied, you have appeal options, and a stronger nexus opinion on a supplemental claim often turns a denial into a grant. See how to increase a VA rating for ways to push a rating higher.

Related and secondary considerations

PTSD tends to sit at the center of a cluster of secondary conditions. Many veterans who claim hypertension secondary to PTSD also have sleep problems — and sleep apnea secondary to PTSD is itself a frequently granted secondary claim worth pursuing on its own. Chronic high blood pressure can, over time, contribute to other cardiovascular and kidney issues that may be separately claimable. The practical takeaway is to treat your service-connected mental health condition as a hub: map every physical condition that flows from it with your provider, document each one, and make sure none are left off the record. Doing so often surfaces compensation veterans would otherwise miss, and it builds a coherent medical narrative that makes each individual claim more credible.

Key takeaways

• Hypertension can be claimed as secondary to service-connected PTSD when a medical nexus links the two.
• You need a current hypertension diagnosis, a service-connected primary (PTSD), and a nexus opinion.
• The nexus letter is the deciding factor — it should address other risk factors and still connect the dots.
• Even a modest hypertension rating combines with your other ratings to raise your overall percentage.
• Be candid at the C&P exam and verify current rating criteria at VA.gov.

Frequently asked questions

Does the VA automatically connect hypertension to PTSD? No — it is not presumptive. You must provide a medical nexus opinion linking your hypertension to your service-connected PTSD.

What if my blood pressure could be from other causes? That is common. A good nexus letter acknowledges other risk factors but still concludes PTSD is at least as likely as not a cause or aggravator.

Is the extra rating worth it? Often yes — even a lower hypertension rating combines with your existing ratings and can push your combined percentage into a higher bracket.
