    Nehmer and earlier effective dates

    Under the Nehmer court-settlement rules, when the VA adds a new presumptive condition, eligible veterans (or their survivors) who previously filed claims for that condition can receive retroactive benefits dating back to the or to the date of death — sometimes producing six-figure back-pay awards.

    If a Vietnam-era or their family had a prior denial for one of the listed conditions, it is worth re-filing as a to evaluate Nehmer eligibility.

    How these claims are filed

    1. Confirm qualifying service (location and dates).
    2. Confirm the diagnosis is on the presumptive list.
    3. is the typical application form for this with current medical records confirming the diagnosis.
    4. If a previous was denied for a now-presumptive condition, file a citing the addition of the condition to the list.
    5. Survivors of veterans who died from a presumptive condition should also evaluate eligibility.

    Where these claims break down

    • ×Not filing because of a prior denial — Nehmer rules may produce substantial back pay.
    • ×Assuming Blue Water Navy is excluded — it has been included since the 2019 Act.
    • ×Overlooking secondaries to presumptive conditions (e.g., kidney disease secondary to diabetes).
    • ×Submitting nexus letters that are not needed when the presumption applies.
    • ×Forgetting Thailand base perimeter service or C-123 service as qualifying exposure.
