Connecting COVID-19 / Long COVID to Military Service
COVID-19 / Long COVID represents one of the most significant categories of VA disability claims in recent years, particularly after the PACT Act of 2022 dramatically expanded presumptive service connection for veterans exposed to toxic substances during military service. Veterans who deployed to Southwest Asia, served in Vietnam or the Korean DMZ, lived at Camp Lejeune, worked as firefighter responders using AFFF foam, or served in other environments with documented toxic hazards may qualify for presumptive service connection — meaning VA presumes the toxic exposure caused their condition without requiring detailed proof of causation.
How VA Rates COVID-19 / Long COVID
Conditions filed under toxic exposure pathways are rated using the same rating criteria as the underlying medical condition once service connection is established. The key distinction is in how service connection is proven — presumptive claims do not require a nexus letter. Instead, deployment records and current diagnosis are sufficient. Once service connected, the condition is rated based on its severity using the applicable diagnostic code.
Evidence Required for Your COVID-19 / Long COVID Claim
- Deployment records specifically documenting service in qualifying locations (Vietnam, Southwest Asia, Camp Lejeune, etc.)
- Airborne Hazards and Open Burn Pit Registry registration (VA.gov/AHOBPR)
- Camp Lejeune Presumptive Benefits registry enrollment if applicable
- Current diagnosis from a qualified physician of the claimed condition
- Medical records showing onset and progression of the condition
- VSO (Veterans Service Organization) assistance — highly recommended for presumptive claims
Frequently Asked Questions — COVID-19 / Long COVID and VA Disability
What is the PACT Act and how does it affect COVID-19 / Long COVID claims?
The PACT Act (Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act) signed August 10, 2022 is the most significant expansion of veteran benefits in decades. It created presumptive service connection for veterans exposed to burn pits, airborne hazards, and other toxic substances during service. If you deployed to qualifying locations after August 2, 1990 and have a qualifying condition, you may be eligible without proving direct causation. Claims should be filed as soon as possible since some provisions have effective date implications.
Do I need a nexus letter for COVID-19 / Long COVID under presumptive service connection?
No. Presumptive service connection means the VA accepts that your deployment or service in the qualifying location is sufficient to establish service connection for covered conditions — you do not need a doctor to write a nexus letter. You do need: (1) documentation of your service in the qualifying location, and (2) a current diagnosis of the covered condition. A VSO can help you determine which specific presumptive categories apply to your particular situation.
What qualifies as military toxic exposure for COVID-19 / Long COVID?
Qualifying toxic exposures include: open burn pit exposure (Southwest Asia deployments 1990–present), Agent Orange exposure (Vietnam, Korean DMZ, Thailand, other locations 1960s–70s), contaminated water at Camp Lejeune (1953–1987), PFAS/AFFF firefighting foam at military installations, radiation exposure from nuclear testing or certain operations, and Gulf War undiagnosed illnesses. Each category has specific eligible service locations and dates — a VSO can verify eligibility for your specific service history.
How do I file a COVID-19 / Long COVID claim with VA?
File VA Form 21-526EZ (Application for Disability Compensation). For toxic exposure claims: (1) identify the relevant exposure category (burn pit, Agent Orange, Camp Lejeune, etc.), (2) attach deployment records or orders showing service in qualifying locations, (3) attach current diagnosis and medical records. The Airborne Hazards and Burn Pit Registry (VA.gov) can generate an exposure history document useful for OEF/OIF/OND veterans. Working with an accredited VSO representative is strongly recommended — they can file at no cost and often identify secondary conditions you may have missed.
