Good for veteransWho: Veterans claiming service connection based on environmental or occupational hazard exposure, including Qarmat Ali National Guard veteransWhy: Under this guidance, a claims processor would accept a veteran's own statement or a buddy statement as proof of exposure to a hazard when it fits their service, so the veteran does not need official records to confirm it. Indiana, West Virginia, South Carolina and Oregon National Guard members at the Qarmat Ali plant between April and September 2003 are also presumed exposed without individua

Good for veteransWho: Survivors and family members who paid a deceased veteran's last illness expensesWhy: Claims processors are told not to deny a deduction for last illness expenses just because the deceased beneficiary already reported the same expenses as unreimbursed medical expenses. Survivors who paid those costs can still reduce their countable income, which can mean a higher or continued pension or DIC benefit.

What changed. M21-1, Part IX, Subpart i, Chapter 3, Section D - Reduction of Income Due to Unreimbursed Expenses Updated to clarify guidance that deductions for previously claimed last illness expenses must not be denied.

MixedWho: Surviving spouses and estates of deceased VeteransWhy: When a Veteran's benefit was being withheld at death (garnishment, apportionment, or similar), the surviving spouse would get only the net month-of-death payment, though the gross amount is paid if the withholding came only from a first-payment cutoff-date issue. The update also tells families that any payments issued in the Veteran's name after death must be returned, usually by automatic re

What changed. M21-1, Part XI, Subpart ii, Chapter 2 - Month of Death (MOD) Benefit Updated to add guidance on paying the Veteran’s month of death payment when withholdings are involved and to clarify how to return payments issued after the Veteran’s death.

Veterans and spouses see no new benefit, right, or requirement; existing rules on resuming payments and recouping erroneous payments are only restated.

What changed. M21-1, Part XI, Subpart i, Chapter 1, Section C - Errors During Notice of Death (NOD) Processing Updated to clarify procedures for errors during NOD processing.

Procedural / no direct effectWho: survivors of service members who died in service and of former POWsWhy: This is an internal instruction update for VA claims processors. They are told to use telephone contact to resolve discrepancies in in-service death DIC claims and to include thanks for service and condolences in all communications. The eligibility rules, benefits, and survivors' filing requirements stay the same, so there is no measurable change in what survivors receive.

What changed. M21-1, Part XII, Subpart i, Chapter 1, Section C - In-Service Death and Former Prisoner of War (FPOW) Dependency and Indemnity Compensation (DIC) Claims Updated to stress the importance of using telephone development and expressing gratitude for the Veteran's service and/or condolences for the loss of a deceased Veteran in all communications.
