Replacement insurance after coverage ends (Marketplace enrollment)

Losing qualifying health coverage can open a short period to buy an individual health plan.

What it is

Losing qualifying health coverage can open a short period to buy an individual health plan.

A coverage loss can open enrollment outside the yearly season. A diagnosis alone does not. The hospital enrollment assister can compare an individual plan with COBRA and Medicaid, including whether treatment would stay in network.

Other details
  • The ordinary loss window is 60 days before or after coverage ends. The post-loss window is 90 days for Medicaid or CHIP.
  • A Medicaid denial opens a window only on the applicable timing branch. A diagnosis alone is not a qualifying event.
  • Voluntarily canceling coverage usually does not create an enrollment right.
What you get
  • A health plan that covers pre-existing conditions.
  • Possible help paying the premium, based on the tax household’s annual income and other rules.
Other details
  • In 2026 enhanced premium credits have expired. The ordinary credit range is 100%–400% of poverty, with no repayment caps.
  • The monthly enrollment window for income at or below 150% of poverty is paused through plan year 2026.
If you decide to apply
  1. Ask the hospital enrollment assister to identify your event and its date using the coverage-end notice.
  2. Compare the exact plan’s hospital, oncology team, medicines and premium with your other options.
  3. Have ready the notice and annual household income estimate; confirm the first premium and coverage start date before choosing.

Other details
  • The enrollment process allows 30 days to send requested documents. Confirm the effective date and first premium with the insurer.
Good to know

The insurer’s name is not enough to confirm your hospital is in network. ARHOME is a separate adult Medicaid route.

Other details
  • Members of federally recognized tribes and ANCSA shareholders have special enrollment and cost-sharing routes.
  • For tax year 2026 the below-100% credit exception for lawfully present immigrants is gone. For tax year 2027, the enacted change limits eligible immigration categories to lawful permanent residents, Cuban/Haitian entrants and COFA migrants. The enrollment assister can check the rules effective for the coverage year.
Official sources
Ask your social worker

“If our coverage ends, what are the benefits and drawbacks of a marketplace plan compared with COBRA or Medicaid, and could you help us check the hospital and deadline?”

Why I’m asking: I want replacement coverage that keeps treatment in reach without a gap or an unexpected premium.

Additional program information and published rules

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

Report the event and date inside the period, send documents within 30 days, and pay the first premium by the insurer's date.

Your social worker

Connects you to an enrollment assister and checks the exact plan against the center's contracts.

The care team

Records and letters when the application asks for them.

Who decides
The Marketplace (eligibility and credit) and the insurer (coverage start)
Ask your social worker
“Does this Marketplace plan cover our center and specialty pharmacy? Who can help compare it with COBRA before we enroll?”

How to apply

First step: Go to HealthCare.gov's special-enrollment page or call 1-800-318-2596 within 60 days of the loss (90 after Medicaid/CHIP), and report the exact event and date.

  1. Identify the event and its date.
  2. Check the treating hospital and specialty pharmacy against the exact plan.
  3. Compare with COBRA before choosing.

Where it starts: HealthCare.gov special-enrollment page or 1-800-318-2596. State exchanges where they exist

What to gather

  • The coverage-loss notice or the Medicaid/CHIP termination letter with dates
  • An annual income estimate for the tax household
  • The names of the treating hospital, oncologists and the specialty pharmacy to check against the plan

How long: Enrollment is immediate once verified (30 days to send documents). Coverage starts the first of the month after you pick a plan and pay.

Clock: 60 days before or after an ordinary coverage loss to enroll.

Clock: 90 days after Medicaid or CHIP ends to enroll.

What a yes looks like

An enrollment confirmation with the premium, the credit and the start date. The hospital confirms it is in network.

What a no looks like, and the next move

“No qualifying event” or “outside the period”. Ask about COBRA or state continuation, and Medicaid, which has no season.

Watch out

  • A diagnosis alone opens nothing. A lost plan, a move, a birth or a Medicaid/CHIP loss does. A Medicaid denial opens a period only on the timing branch. Keep the application and denial dates.
  • Check the exact plan's network for the treating hospital and the specialty pharmacy before paying. “the hospital takes that insurer” is not enough.
  • The enhanced tax credits ended December 31, 2025; higher-income families can lose all premium help. The monthly low-income enrollment period is paused through 2026.
  • Members of federally recognized tribes and ANCSA shareholders have special enrollment and cost-sharing routes. Ask the Marketplace for the tribal eligibility check, the zero- or limited-cost-sharing plan, and how referrals are handled.

Dates that change this

2025-12-31: The enhanced premium tax credits ended December 31, 2025. In 2026 the credit runs from 100% to 400% of the poverty line; above 400% there is none, and repayment caps are gone.

2025-08-25: The monthly enrollment window for households at or below 150% of the poverty line is paused through plan year 2026.

2026-01-01: For tax year 2026 the below-100% exception for lawfully present immigrants is gone; from tax year 2027 the credit is limited to lawful permanent residents, Cuban/Haitian entrants and COFA migrants.

The numbers and the rules

The arcane layer, kept on purpose. Checked September 10, 2026.

What it is worth

An ACA plan that must take a child with cancer, with a premium tax credit between 100% and 400% of the poverty line. Enrollment outside the yearly season.

Legal protection: Pre-existing-condition protection · 60-day period before or after an ordinary coverage loss · 90-day period after loss of Medicaid or CHIP · 30 days to send documents

What it costs the family: Plan-specific premium and cost-sharing. The enhanced credits ended December 31, 2025, so above 400% of the poverty line there is no credit in 2026.
