Natural disasters rank among the most disorienting health coverage crises Americans face. Hurricanes, wildfires, floods, earthquakes, and tornadoes do not just damage homes. They knock out employers, force mass evacuations, destroy insurance documents, and shutter the local offices where people normally seek help. The health system has specific rules for exactly this scenario, but those rules are more nuanced than most disaster guides admit. Two separate enrollment pathways exist: the standard loss-of-coverage Special Enrollment Period (SEP) that kicks in when a disaster actually causes your coverage to lapse, and the FEMA Exceptional Circumstances SEP that extends an enrollment window you were already eligible for when the disaster struck. The distinction matters because the eligibility criteria, the clock start dates, and the documentation requirements differ between the two pathways. Getting the wrong pathway sends your application to the wrong process and can cost you coverage during recovery when you need it most. This guide covers both pathways, the documents you need to prove your qualifying life event in 2026, and the parallel Medicaid enrollment track that operates with no deadline at all for lower-income disaster survivors.
Three critical facts anchor this guide. First, the FEMA Exceptional Circumstances SEP at healthcare.gov applies only when a FEMA-declared disaster struck during an enrollment window you were already in, such as Open Enrollment or a prior SEP from a separate qualifying life event. A disaster that happens outside any enrollment window does not automatically create a new Marketplace SEP on its own, but it frequently triggers one of the standard SEP categories: loss of coverage, involuntary relocation, or income change triggering Medicaid eligibility. Second, state-based Marketplaces (Covered California, GetCoveredNJ, NY State of Health, and others) operate under their own rules and many provide broader disaster enrollment access than the federal Marketplace at healthcare.gov. Third, FEMA Individual Assistance and FEMA disaster relief grants do not count as income for Medicaid eligibility calculations or ACA subsidy income, per federal guidance and a 2025 legislative proposal (S.2071) that seeks to formalize that protection. Disaster survivors in 2026 should check Medicaid eligibility first before assuming they need a paid Marketplace plan. In states like Medi-Cal in California, AHCCCS in Arizona, and MassHealth in Massachusetts, income thresholds are higher or enrollment is broader for disaster-affected residents.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
Disaster survivors make these coverage errors most often. Each one can leave you uninsured for weeks or months:
- Assuming any disaster automatically triggers a Marketplace SEP. The FEMA Exceptional Circumstances SEP at healthcare.gov applies only when the disaster struck during an enrollment window you were already eligible for (Open Enrollment or an existing SEP). If the disaster hits during a coverage gap or outside any enrollment period, your SEP pathway is the loss-of-coverage SEP, the move SEP, or Medicaid, not the FEMA exceptional-circumstances route.
- Counting FEMA disaster grants as income when applying for subsidies. FEMA Individual Assistance payments are not counted as MAGI income for ACA subsidy eligibility or Medicaid eligibility. Including them inflates your income estimate and could disqualify you from subsidies or Medicaid you rightfully deserve.
- Defaulting to COBRA without comparing Marketplace plan costs. COBRA charges 102% of the full premium, often $800 to $2,000 per month for an individual. After a disaster that reduces income, most survivors qualify for large premium tax credits that make Silver Marketplace plans $0 to $150 per month. Check healthcare.gov for your actual subsidy amount before electing COBRA.
- Forgetting to check Medicaid first. Disasters frequently cause income drops that create Medicaid eligibility where none existed before. Medicaid is free, enrolls year-round, and does not have a 60-day clock. In 40 expansion states plus DC, the 2026 threshold is $22,025 for a single person. If you even might qualify, apply first before shopping Marketplace plans.
- Contacting the federal Marketplace call center if you live in a state-based exchange state. California (Covered California), New York (NY State of Health), New Jersey (GetCoveredNJ), Massachusetts (MA Health Connector), Colorado (Connect for Health Colorado), and several other states run their own exchanges with their own disaster SEP rules. The federal 1-800-318-2596 line cannot enroll you in a state-exchange plan. Call your state exchange directly.
- Missing the separate 60-day COBRA election window. Even if you plan to use a Marketplace SEP, you have 60 days from the qualifying event to elect COBRA. If you need bridge coverage while you compare Marketplace plans, you can elect COBRA and then drop it once your Marketplace plan starts, as long as you act within the 60-day window.
Two Separate Pathways: FEMA Exceptional Circumstances vs Loss-of-Coverage SEP
FEMA Exceptional Circumstances SEP and loss-of-coverage SEP are different legal mechanisms that disaster survivors often conflate. The FEMA Exceptional Circumstances SEP under federal regulations (45 CFR 155.420) applies specifically when a FEMA-declared disaster or emergency struck your area during an enrollment window you were already eligible for, such as Open Enrollment (November 1 through January 15 for 2026 coverage) or a prior Special Enrollment Period you had earned from a separate qualifying event. The disaster prevented you from completing your enrollment, so CMS extends your window by 60 days from the close of the FEMA incident period. To use this pathway, call healthcare.gov at 1-800-318-2596, attest to residing in a FEMA-designated Individual Assistance or Public Assistance county during the incident period, and confirm you could not complete enrollment due to the disaster. The coverage effective date can be retroactive to the date you would have had coverage if not for the disaster.
Loss-of-coverage SEP is the separate, independent pathway triggered when a natural disaster causes actual termination of your health coverage. Common disaster-related triggers include employer business closure (which terminates the group health plan), a health insurer exiting a disaster-affected county or state market, or coverage being terminated because your household cannot maintain premium payments following income loss. The loss-of-coverage SEP gives you 60 days from the date coverage actually ends, not the date of the disaster itself. Critically, a disaster happening outside any enrollment window still creates a loss-of-coverage SEP if coverage is actually terminated, regardless of FEMA declaration status. Employers with 20 or more employees must offer COBRA for 18 months; employers with fewer than 20 employees in many states have state mini-COBRA obligations with varying timeframes.
State-Based Marketplace Rules: California, New York, New Jersey, and Beyond
Sixteen states and the District of Columbia operate their own health insurance Marketplaces independent of healthcare.gov. These state-based exchanges control their own disaster SEP rules and many offer broader enrollment access after disasters than the federal Marketplace provides. Covered California (California's exchange) is the most significant example: after a state or federal disaster declaration, Covered California typically opens a 60-day SEP for all residents of affected counties without requiring them to have been in an existing enrollment window, a materially broader rule than the federal FEMA Exceptional Circumstances pathway. During the January 2025 Southern California wildfires, Covered California specifically announced emergency enrollment for all affected county residents. Residents of California must contact Covered California at 1-800-300-1506 or coveredca.com, not the federal healthcare.gov call center, to access disaster enrollment.
Other state exchanges with disaster-specific rules include NY State of Health (New York), GetCoveredNJ (New Jersey), MA Health Connector (Massachusetts), Connect for Health Colorado (Colorado), and kynect (Kentucky). Each has different trigger criteria for disaster enrollment. Residents of these states should contact their state exchange directly rather than calling the federal 1-800-318-2596 number, which cannot process state-exchange applications. The 10 non-expansion states (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, Wyoming) rely almost entirely on the federal Marketplace at healthcare.gov and CHIP for children, since Medicaid income thresholds are very low for non-disabled adults. Disaster survivors in non-expansion states face a coverage gap if income is too high for strict Medicaid but too low to afford unsubsidized Marketplace plans, though subsidies often help substantially even at low incomes.
Medicaid Eligibility After a Natural Disaster in 2026
Medicaid is the most underutilized post-disaster coverage option among working-age adults. Natural disasters frequently cause immediate income drops that push households below the Medicaid eligibility threshold, creating eligibility where none existed before the event. Medicaid enrollment is year-round with no SEP deadline. The 40 expansion states plus DC cover adults at incomes up to 138% FPL in 2026: that is $22,025 for a single person and $45,540 for a family of 4 per HHS ASPE 2026 Poverty Guidelines. State Medicaid programs operate under distinct brand names: Medi-Cal in California, AHCCCS (pronounced Ax) in Arizona, MassHealth in Massachusetts, BadgerCare in Wisconsin, HUSKY Health in Connecticut, TennCare in Tennessee, and Medicaid by its generic name in most other states. Apply through your state Medicaid agency or through healthcare.gov, which routes applicants to the correct state program automatically. Applications submitted during a disaster can often receive expedited processing under state emergency procedures.
FEMA Individual Assistance grants, disaster relief payments, and Disaster Unemployment Assistance received from FEMA do not count as MAGI income for Medicaid eligibility, per federal guidance. This means disaster survivors should calculate their income excluding FEMA payments when determining Medicaid eligibility. A proposed Senate bill (S.2071, Disaster Relief Medicaid Act, 119th Congress) would formalize this protection by statute and also prohibit states from conducting Medicaid redeterminations for disaster-affected enrollees during a declared disaster period. Under current rules, enrollees in non-expansion states who do not qualify for Medicaid can still access CHIP for children, and the ACA Marketplace income limits table above shows the subsidy cliff at 400% FPL for 2026. Children qualify for CHIP at incomes typically between 200% and 300% FPL regardless of expansion status, making CHIP a critical resource in disaster zones in non-expansion states like Texas and Florida.
Documents Needed for Each Disaster SEP Pathway in 2026
Documentation requirements differ by pathway. For the FEMA Exceptional Circumstances SEP, you primarily need to attest verbally by phone (calling 1-800-318-2596) that you resided in a FEMA Individual Assistance or Public Assistance county during the incident period and that the disaster prevented you from completing your enrollment. No written documentation is typically required for the attestation, but CMS may request post-enrollment verification in some cases. Have your county name, state, and the FEMA disaster declaration number available when you call. For the loss-of-coverage SEP, you need written documentation that your coverage terminated: a COBRA election notice from your former employer, a coverage termination letter from your insurer, a plan discontinuation notice, or documentation that your employer closed permanently. HIPAA certificates of creditable coverage are also acceptable proof of prior coverage. For Medicaid applications, documentation requirements are lighter: states generally accept self-attestation of income and can verify coverage electronically through federal data hubs. Upload supporting documents only if your state specifically requests them.
Frequently Asked Questions
How long do I have to get health insurance after a natural disaster?
Two separate windows apply. If the disaster caused your coverage to end (employer closed, insurer left your area), you have a standard 60-day loss-of-coverage Special Enrollment Period from the date your coverage actually ends. If the disaster struck while you were already in Open Enrollment or another SEP window and prevented you from completing enrollment, the FEMA Exceptional Circumstances SEP gives you 60 days from the close of the FEMA incident period to enroll at healthcare.gov by calling 1-800-318-2596. Medicaid has no deadline and enrolls year-round for qualifying incomes. State-based exchanges like Covered California may have broader rules.
Does a natural disaster automatically trigger a Special Enrollment Period?
Not automatically, and not always. The FEMA Exceptional Circumstances SEP at healthcare.gov requires that the disaster struck during an enrollment window you were already eligible for, such as Open Enrollment or a prior qualifying event SEP, and that you were unable to complete enrollment because of the disaster. If the disaster happens outside any enrollment window, the SEP that applies depends on whether it caused you to actually lose coverage (60-day loss-of-coverage SEP), forced you to relocate (60-day move SEP), or reduced income enough to qualify for Medicaid (year-round, no deadline). Contact 1-800-318-2596 to determine which pathway fits your situation.
Do I have to live in a FEMA-declared disaster county to qualify for the disaster SEP?
For the FEMA Exceptional Circumstances SEP specifically, yes, your county generally must have been designated for Individual Assistance or Public Assistance by FEMA for the Marketplace to grant this enrollment extension. Check fema.gov/disaster/declarations to confirm your county designation. However, if you personally lost coverage regardless of county designation (employer went out of business, insurer exited your market), you can still qualify for the standard loss-of-coverage SEP without a formal FEMA designation. Individual exceptions may also be granted on a case-by-case basis by calling healthcare.gov directly.
Do FEMA disaster grants count as income when I apply for ACA subsidies or Medicaid?
No. FEMA Individual Assistance payments, disaster relief grants, and Disaster Unemployment Assistance from FEMA are excluded from Modified Adjusted Gross Income (MAGI) calculations for both ACA Marketplace subsidy eligibility and Medicaid eligibility. Do not list FEMA grants as income on your Marketplace or Medicaid application. Use only your projected earned income, regular unemployment compensation (which does count), and other standard income sources when calculating your 2026 household income for subsidy and Medicaid eligibility purposes.
I live in California. How is my disaster SEP different from the federal rules?
California operates Covered California, its own state exchange, which sets independent disaster SEP rules. After a state or federal disaster declaration, Covered California typically opens a 60-day SEP for all residents in affected counties, regardless of whether they were in a prior enrollment window when the disaster struck. This is materially broader than the federal FEMA Exceptional Circumstances SEP, which requires a prior enrollment window. Residents of California must contact Covered California at 1-800-300-1506 or coveredca.com. Calling the federal 1-800-318-2596 number will not enroll you in a Covered California plan. California's Medi-Cal (Medicaid) also enrolls year-round.
What if my state has not expanded Medicaid? What are my options after a disaster?
Ten states have not expanded Medicaid (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, Wyoming), leaving adults without dependent children with very limited Medicaid eligibility. Disaster survivors in non-expansion states rely primarily on the federal Marketplace loss-of-coverage SEP or FEMA Exceptional Circumstances SEP, and COBRA continuation. Children in non-expansion states can access CHIP at incomes up to 200% to 300% FPL, which is a critical resource. Disaster survivors in Texas and Florida, for example, should apply at healthcare.gov for the Marketplace SEP and separately enroll children in their state CHIP program through Medicaid agency portals.
What happens to my health coverage if I had to evacuate and move to a different state?
Relocating to a different state is a qualifying life event (moving to a new coverage area) that triggers a 60-day move-triggered Special Enrollment Period. Your old Marketplace plan may not cover out-of-state care. You can enroll in a new plan in the state you moved to within 60 days of establishing a new address. Medicaid does not transfer between states; you must apply to the new state's Medicaid program, and eligibility restarts. Your old employer's COBRA coverage follows you (you can use any in-network provider nationally under most COBRA plans), but you still have the 60-day election window from the original qualifying event. Document your relocation with a utility bill, lease agreement, or FEMA disaster assistance notice showing your new address.
Can I get retroactive coverage back to the disaster date?
For the FEMA Exceptional Circumstances SEP, yes, you can request that your coverage start retroactively on the date you would have had coverage if you had been able to complete enrollment during your original window. Contact healthcare.gov at 1-800-318-2596 to request a retroactive effective date. For the standard loss-of-coverage SEP, coverage generally starts on the first of the month following plan selection under regular effective date rules, but you may be able to request an earlier start date in some circumstances. Medicaid coverage in many states can be retroactive to the date you applied or up to 3 months before application in states that maintain retroactive eligibility, though some states have limited or eliminated retroactive coverage. Ask your state Medicaid agency about retroactive eligibility at application.
