Free Viability Check →Hypertension is one of the most common conditions veterans file for, and one of the most commonly denied. The frustrating part is that high blood pressure is rarely denied because it isn't real. It's denied because the file never connected it to service. That connection, the nexus, is almost always the missing piece, and it's usually fixable.
Here's the honest landscape of how hypertension gets service connected, which pathways actually hold up, and what a rater needs to see.
Hypertension is a chronic disease under 38 CFR 3.309(a). If it was diagnosed, or showed up as elevated readings, within one year of your separation from active duty, it can be presumptively service connected. No nexus letter required in that scenario. So before anything else, pull your separation physical and your first year of post-service records. If your blood pressure was already climbing then, that's your strongest and simplest path.
Most veterans miss this window, though, because hypertension is silent. It gets diagnosed years later at a routine visit. That's when the other pathways matter.
Under the 2022 PACT Act, hypertension became a presumptive condition for certain veterans exposed to Agent Orange. If you served in a location and time window that qualifies for herbicide exposure, your high blood pressure may be presumptive without a nexus letter at all. Check whether your service fits an established exposure category first. If it does, that's the easiest route. If it doesn't, you're back to building the connection yourself, and that's where most people are.
For the majority of veterans, hypertension gets service connected as a secondary condition, meaning it was caused or aggravated by another condition that's already service connected. These are the pathways with real medical support behind them:
There's well-established medical literature connecting chronic PTSD to sustained high blood pressure. The mechanism is real: chronic hyperarousal keeps the sympathetic nervous system activated, and over years that drives blood pressure up. If your PTSD is service connected and your hypertension came later, this is often the strongest argument available.
Obstructive sleep apnea and hypertension have a bidirectional relationship. Repeated overnight oxygen drops stress the cardiovascular system, and moderate-to-severe sleep apnea is a recognized contributor to high blood pressure. If your OSA is service connected, hypertension secondary to it is a well-supported claim.
Service-connected kidney conditions can drive secondary hypertension directly. Chronic pain conditions contribute too, both through the physiological stress response and through the medications and reduced activity that often come with them.
Some medications prescribed for service-connected conditions raise blood pressure as a side effect. If you were put on a drug for a service-connected condition and your blood pressure rose afterward, that's a documentable pathway.
Whatever the pathway, three things have to be in the file:
That third piece is what the VA found missing in most denials. Under Nieves-Rodriguez v. Peake (22 Vet. App. 295, 2008), the value of a medical opinion comes from its reasoning, not from who signed it. A well-reasoned private nexus letter can outweigh a bare C&P conclusion.
A denial isn't the end. You generally have one year from the rating decision to file a Supplemental Claim with new and relevant evidence and keep your original effective date. For most hypertension denials, that new evidence is a private nexus letter that addresses the exact gap the VA named. Read the rating decision's rationale word for word first, then respond to the specific reason they gave. Refiling the same claim with no new evidence gets the same result.
Hypertension claims are winnable when the connection is documented properly. The most common fix is a physician-reviewed nexus letter built around your actual records and the specific pathway that fits your case.
Flat Rate Nexus writes physician-signed independent medical opinions for hypertension claims. A board-certified physician reviews your records for a flat $50, and you only pay for the letter if your case is supportable. You can also run a free case check first to see whether it's worth pursuing at all.
Thinking about your own claim? Every nexus letter we write goes through a full physician record review, cites peer-reviewed research, and is built around the actual evidence in your case.
