VA Decision on Hypertension and Agent Orange: 0% Ratings and Appeals

The VA rates hypertension linked to Agent Orange under a strict blood pressure schedule that runs from 0% to 60%, and the Agent Orange hypertension VA rating most veterans actually receive is 0% — service-connected but non-compensable — because the readings are taken after medication has already brought the numbers down. Hypertension became a presumptive Agent Orange condition when President Biden signed the PACT Act on August 10, 2022, meaning qualifying veterans no longer have to prove their high blood pressure was caused by service.¹ Winning the service connection is now the easy part. Getting a rating that actually pays is where the work happens.

How the VA Rates Hypertension

The rating schedule sits in 38 CFR § 4.104, Diagnostic Code 7101. The VA looks at your blood pressure readings and assigns a percentage based on where the numbers fall:²

10% — diastolic pressure predominantly 100 or more, or systolic pressure predominantly 160 or more, or a history of diastolic pressure predominantly 100 or more requiring continuous medication for control.
20% — diastolic pressure predominantly 110 or more, or systolic pressure predominantly 200 or more.
40% — diastolic pressure predominantly 120 or more.
60% — diastolic pressure predominantly 130 or more.

Anything below the 10% threshold gets a 0% rating. Service-connected, but no monthly check.

Why So Many Veterans Get 0%

According to the Disabled American Veterans, more than 82% of PACT Act hypertension claims have resulted in a 0% rating.³ The reason is baked into the schedule. The VA evaluates blood pressure as measured, and by the time most veterans file, they have been on medication for years. Medication is doing its job; the readings look controlled; the rater sees numbers below 100 diastolic and assigns 0%.

The route to 10% runs through the schedule’s third clause: a history of diastolic pressure predominantly 100 or more that requires continuous medication for control. You need to show both pieces. The medication requirement is usually easy to document with a current prescription. The historical readings are harder, because they have to come from before the medication took hold.³

What helps: pre-treatment medical records from the doctor who first diagnosed you, emergency room visits documenting hypertensive urgency, workplace physicals, insurance exams, and personal statements describing how bad the readings were before you started taking pills. If any of that evidence exists, get it into the file. A single well-documented set of pre-medication readings above 100 diastolic can move a claim from 0% to 10%.

What a 0% Rating Still Gets You

A 0% rating pays nothing, but it is not nothing. It establishes service connection, which opens the door to VA health care, prescription coverage, copayment waivers, and federal hiring preference.³ It also becomes the foundation for secondary claims, which is often where the real compensation comes from.

Secondary Conditions

Hypertension damages the cardiovascular system, kidneys, and brain over time, and the VA will rate conditions that develop as a result of a service-connected hypertension. A secondary claim requires a current diagnosis of the new condition and a medical opinion (a nexus letter) stating it is at least as likely as not that the condition was caused or aggravated by the hypertension.

Common secondary conditions include:

Ischemic heart disease, rated 10% to 100% based on cardiac function and exercise capacity.
Chronic kidney disease, rated 0% to 100% depending on creatinine levels, dialysis requirements, and symptoms.
Stroke, rated at 100% for six months after final treatment, then based on residual impairments.
Sleep apnea, rated 0% to 100%, with 50% assigned when a CPAP machine is required.
Peripheral artery disease, rated 20% to 100%.
Erectile dysfunction, rated at 0% but potentially qualifying for Special Monthly Compensation.

Secondary ratings combine with the primary hypertension rating under the VA’s combined ratings formula and can pull a total disability percentage up substantially. If your combined rating reaches 70% with at least one condition at 40%, Total Disability based on Individual Unemployability may pay at the 100% rate when the disabilities prevent substantially gainful employment.

Who Qualifies for the Presumption

None of this matters unless you served in a qualifying place during a qualifying window. The VA presumes hypertension is service-connected for veterans who served in the following locations and dates:⁴

Republic of Vietnam — land, inland waterways, or territorial waters, January 9, 1962 through May 7, 1975.
Thailand — any U.S. or Royal Thai military base, January 9, 1962 through June 30, 1976.
Blue Water Navy — aboard a vessel in Vietnam’s inland waterways or within 12 nautical miles of the demarcation line of Vietnam and Cambodia’s waters, January 9, 1962 through May 7, 1975.
Korean DMZ — in or near the demilitarized zone, September 1, 1967 through August 31, 1971.
Laos — December 1, 1965 through September 30, 1969.
Cambodia — at Mimot or Krek, April 16, 1969 through April 30, 1969.
Guam or American Samoa — on the islands or in territorial waters, January 9, 1962 through July 31, 1980.
Johnston Atoll — on the atoll or on a ship that called there, January 1, 1972 through September 30, 1977.
C-123 aircraft — service involving C-123 aircraft previously used to spray Agent Orange, or involvement in its testing or storage.

Blue Water Navy veterans were added through the Federal Circuit’s 2019 Procopio v. Wilkie ruling and the Blue Water Navy Vietnam Veterans Act, which took effect January 1, 2020.⁵⁶

Filing or Refiling a Claim

For a presumptive claim you need two things: a medical record showing a current diagnosis of hypertension, and military records (usually a DD214) confirming service in one of the qualifying locations during the applicable dates.⁴ No nexus letter is required to connect the hypertension to service.

If you have never filed, submit a new claim at VA.gov, by mail, in person at a regional office, or through an accredited representative.⁷ If your hypertension claim was denied before August 2022, file a Supplemental Claim. That triggers a review under the new presumptive rules. You do not need to wait for the VA to contact you first.

The window for backdated benefits to the PACT Act’s effective date has closed. Veterans who filed or submitted an intent to file by August 9, 2023, were eligible for 12 months of backdated compensation reaching to August 10, 2022.⁸ For claims filed after that deadline, benefits generally run from the application date. Previously denied Blue Water Navy claims may pay back to the date of the original claim.⁴

Appeals When the Rating Is Too Low

A 0% rating, or any rating you believe understates the condition, can be challenged through three paths under the Veterans Appeals Improvement and Modernization Act:

Supplemental Claim. You submit new and relevant evidence — pre-medication blood pressure readings, older treatment records, an independent medical opinion. This is the right path when you have documentation the VA did not see the first time around.
Higher-Level Review. A senior VA reviewer takes a fresh look at the existing record. No new evidence allowed. Use this when you believe the rater overlooked evidence already in the file or misapplied the regulation.
Board of Veterans’ Appeals. An appeal to a Veterans Law Judge, with three tracks: direct review of the existing record, review with additional evidence, or a hearing.

County veteran service officers, the Disabled American Veterans, and accredited attorneys can help at any stage. The VA’s benefits line is 1-800-698-2411, and claims can be tracked at VA.gov or through the VA: Health and Benefits mobile app.⁷

Claims Numbers Worth Knowing

Hypertension is the single most-claimed condition under the PACT Act. As of March 15, 2025, the VA had received 516,627 hypertensive vascular disease claims, with about 65% granted and 35% denied.¹ That grant rate covers service connection, not compensable ratings; the DAV figure showing 82% at 0% is the more honest picture of what most veterans walk away with on the first decision. Which is why the evidence you gather before filing, and the appeal path you choose after, matters more than the presumption itself.
