Is hypertension secondary to PTSD a recognized VA claim?

Yes. The VA recognizes hypertension as a condition that can be caused or aggravated by service-connected PTSD. The chronic stress response associated with PTSD elevates cortisol and catecholamines, which drive sustained increases in blood pressure.

What rating does hypertension receive from the VA?

Hypertension is rated under Diagnostic Code 7101. Ratings of 10%, 20%, 40%, and 60% are based on diastolic and systolic blood pressure readings. Most veterans with well-managed hypertension receive 10% or 20%.

Do I need a nexus letter to connect hypertension to PTSD?

Yes. A physician's written opinion using the 'at least as likely as not' standard is required. The letter should reference your PTSD diagnosis, treatment history, and the established medical literature on the PTSD-hypertension relationship.

What blood pressure readings qualify for a VA rating?

A 10% rating requires diastolic pressure predominantly 100 or more, or systolic pressure predominantly 160 or more, or at least one reading above those thresholds requiring medication. Higher sustained readings yield higher ratings.

Can hypertension be secondary to PTSD even if I have other risk factors?

Yes. The VA's aggravation standard only requires showing that PTSD made your hypertension worse than it would otherwise be. Pre-existing risk factors do not automatically defeat a secondary claim.

What Is Hypertension Secondary to PTSD?

High blood pressure is one of the most pervasive health consequences of PTSD — and one of the most winnable secondary claims a veteran can file. The biological link between chronic psychological trauma and elevated blood pressure is well established in medical literature, and the VA regularly grants this connection when supported by proper evidence.

Hypertension (high blood pressure) is defined as sustained blood pressure readings above 130/80 mmHg. When left uncontrolled, it is a major driver of stroke, heart attack, kidney damage, and other serious complications. For veterans with PTSD, the relentless activation of the stress response system means their cardiovascular systems operate at a higher baseline, and this chronic load translates directly into elevated pressure.

The secondary claim pathway requires you to establish that your PTSD — not just general lifestyle factors — contributed to your hypertension. With the right nexus evidence, many veterans have successfully made this connection and received ratings between 10% and 60%.

Why the VA Recognizes This Connection

The physiological relationship between PTSD and hypertension runs through several well-documented pathways:

Chronic sympathetic nervous system activation. PTSD keeps the body in a state of heightened alert. The "fight or flight" response — mediated by the sympathetic nervous system — causes repeated surges in heart rate and blood pressure. Over time, sustained sympathetic activation causes the vasculature to remodel, making elevated blood pressure a persistent rather than episodic condition.

Cortisol and catecholamines. PTSD dysregulates the HPA (hypothalamic-pituitary-adrenal) axis, leading to abnormal cortisol patterns and elevated epinephrine and norepinephrine. These hormones directly raise blood pressure by increasing heart rate, constricting blood vessels, and promoting sodium retention in the kidneys.

Sleep disruption. PTSD-related sleep disturbance is itself a risk factor for hypertension. Poor sleep — especially fragmented or shortened sleep — is associated with nocturnal hypertension and blunted dipping (the normal nighttime decrease in blood pressure), compounding cardiovascular risk.

Inflammation. Chronic PTSD is associated with elevated inflammatory markers. Systemic inflammation damages vascular endothelium and contributes to arterial stiffness — a direct precursor to sustained hypertension.

Studies have shown that veterans with PTSD have meaningfully higher rates of hypertension than matched controls, and that PTSD severity correlates with blood pressure elevation. The VA's own research supports this connection. For more on how the VA evaluates cardiovascular conditions, see the VA's disability compensation page.

Evidence That Wins This Claim

Blood pressure records: Serial measurements from VA or private care documenting consistently elevated readings over time. Single readings are less compelling than a documented pattern.
PTSD service connection documentation: Your rating decision and C&P reports establish the primary condition anchoring the secondary claim.
Private nexus letter: A physician's opinion linking the physiological mechanisms of PTSD to your hypertension using the "at least as likely as not" standard.
VA mental health treatment notes: Records showing your PTSD symptoms, severity, and duration help establish the biological load that drove your blood pressure elevation.
Cardiology or internal medicine records: Specialist documentation of hypertension diagnosis, severity, and treatment strengthens the medical record.
Medication records: Antihypertensive prescriptions — particularly if they started or escalated after PTSD onset — support the timeline connection.
Buddy statements: Family members who observed behavioral changes (hypervigilance, sleep disruption, agitation) during the same period blood pressure rose can provide corroborating lay evidence.

How the VA Rates Hypertension

Hypertension is rated under Diagnostic Code 7101 based on blood pressure readings:

Rating	Criteria
60%	Diastolic pressure predominantly 130 or more
40%	Diastolic pressure predominantly 120 or more
20%	Diastolic pressure predominantly 110 or more, or systolic 200 or more
10%	Diastolic 100 or more, or systolic 160 or more, or minimum medication required

The VA looks at the predominant blood pressure reading — meaning sustained elevations across multiple readings, not a single high measurement. Veterans whose hypertension is well-controlled by medication may still receive a 10% rating based on the medication requirement alone.

Why These Claims Get Denied — And How to Prevent It

Missing nexus letter. Hypertension is a common condition with many known risk factors (diet, age, genetics). The VA will attribute it to general lifestyle factors unless a physician specifically links it to PTSD. A nexus letter is not optional — it is the central piece of evidence.

Insufficient blood pressure documentation. One or two elevated readings do not establish hypertension under VA criteria. Ensure your medical record contains serial measurements over time that meet the diagnostic threshold.

Weak nexus language. "May be related" does not meet the VA's standard. The nexus letter must state "at least as likely as not" that PTSD caused or aggravated the hypertension.

C&P examiner attributing BP to lifestyle only. Some examiners default to listing general risk factors without addressing the PTSD mechanism. Submitting a thorough nexus letter before the C&P exam makes it harder for the examiner to avoid the secondary theory.

Failure to document PTSD severity over time. Claims with thin PTSD treatment records struggle to establish the chronic stress load that caused the hypertension. Ensure your VA mental health records are robust before filing.

Sample Nexus Letter Language

"I have reviewed [Veteran's name]'s complete medical records, including VA rating documentation for service-connected PTSD and cardiovascular records documenting hypertension with consistently elevated readings. In my professional medical opinion, it is at least as likely as not that [Veteran's name]'s hypertension was caused or materially aggravated by their service-connected PTSD. The chronic sympathetic nervous system activation and HPA axis dysregulation associated with PTSD are well-established drivers of sustained blood pressure elevation. The timeline of [Veteran's name]'s blood pressure documentation correlates with the progression of PTSD symptomatology. This opinion is based on my clinical review of the record and established medical research on the relationship between PTSD and cardiovascular disease."
