PACT Act Presumptives in 2026: When a Previously Denied Claim Deserves Another Look

Ordinarily, service connection requires evidence linking a current disability to service. When a condition and service history meet a valid presumption, VA generally presumes the required connection instead of demanding a separate medical nexus on that point.

The PACT Act added more than 20 presumptive conditions involving burn pits and other toxic exposures, expanded Agent Orange and radiation locations, and added hypertension and monoclonal gammopathy of undetermined significance to the Agent Orange list.

• Confirm a competent current diagnosis and the condition’s severity.
• Verify service in the correct place and during the controlling dates.
• Match the diagnosis precisely to the applicable presumptive list.
• Review whether another service-connection theory may be stronger or preserve an earlier effective date.
• Audit prior claim wording and decisions before assuming VA never considered the same condition.

VA’s current guidance says a Veteran whose condition is now presumptive may file a Supplemental Claim and ask VA to review the matter again. The filing should identify the prior issue, the change in law, the qualifying service, and medical evidence documenting the diagnosis and severity.

Effective dates under liberalizing-law and continuous-pursuit rules can be technical. Do not promise that a new presumption will create back pay to the date of the original claim.
