Hypertension claims are decided on documentation more than on testimony. The regulation sets specific numeric thresholds and a specific confirmation requirement, which means the completeness of the record usually determines the outcome.
This guide covers what to gather and where records commonly come up short. For the underlying rules, see how hypertension service connection works and the ratings guide.
Start with the readings
Blood pressure readings are the backbone of the file. Useful sources include service treatment records, separation physicals, VA treatment records, private primary care records, employer physicals, and urgent care visits.
38 CFR 4.104 requires confirmation by readings taken two or more times on at least three different days, so readings spread across visits carry more weight than a cluster from a single appointment.
Treatment history
Medication records establish what has been prescribed, when it started, and how the regimen changed over time. For the minimum 10 percent rating, the history matters as much as the current prescription: the criteria reference a history of diastolic pressure predominantly 100 or more together with a continuing need for medication.
- Pharmacy records showing the start date and dose changes
- Notes documenting adjustments because control was inadequate
- Records of any period when medication was stopped and pressure rose
- Documentation of related cardiovascular or kidney findings
Records from the first year after service
Because hypertension is among the chronic diseases in 38 CFR 3.309(a), manifestation to a compensable degree within one year of separation can support presumptive service connection under 38 CFR 3.307. Records from that window are disproportionately valuable and are frequently the ones veterans have not collected.
Where veterans start
Every case is different, and there is no obligation at any step. When veterans want to understand what their records actually support, these are the two most common starting points:
- Medical records review
A licensed physician reviews your records for a $250 flat fee and identifies which conditions the available evidence may support. The fee is refunded in full if nothing supportable is identified.
- Nexus letter
When the records support one, a licensed provider writes the medical opinion that addresses the link between your blood pressure condition and your service or an already service-connected disability.
Lay statements - and their limits
A veteran can describe symptoms and observable events, and family members can describe what they witnessed. Lay evidence cannot establish blood pressure values, because those require measurement. Statements are most useful for context: when symptoms began, what a provider said at the time, and why a period of care went undocumented.
Where hypertension records commonly fall short
The same gaps recur across these claims:
- Readings recorded at only one or two visits, short of the confirmation requirement
- No records from the year after separation
- Missing pre-medication readings, leaving the required history undocumented
- Private records the VA never obtained because they were not submitted
- A secondary theory with no opinion connecting it to the service-connected condition
The medical opinion
When the connection to service is the contested element, a reasoned medical opinion is the evidence that addresses it. A useful opinion reviews the actual records, identifies the claimed pathway, addresses competing causes, and reaches a conclusion under the “at least as likely as not” standard when the evidence supports one.
A paid medical records review is where that determination starts - a licensed physician reviews what you have and identifies what the evidence may support before a nexus letter is ordered. Secondary theories are covered in our guides on PTSD, sleep apnea, and diabetes.
