ACA Open Enrollment 2027 for People With Cancer: 7 Plan Details to Check Before You Renew
Premiums are up again, the out-of-pocket limit rises to $12,000 and some insurers are leaving. For anyone in treatment or follow-up care, the network, drug list and yearly cost cap matter more than the monthly price.

If you have cancer, or had it, health insurance is not an abstract budgeting decision. It decides whether your oncologist is in network, whether your oral chemotherapy costs $50 or $5,000 a month and whether a scan gets approved in days or weeks. Open enrollment for 2027 marketplace coverage began Nov. 1, and the plan you choose now will shape a full year of care.
This year carries more risk than usual. Premiums are rising for a second straight year, the federal out-of-pocket limit climbs to $12,000 for one person, and several insurers are leaving states. A plan that worked during 2026 treatment may look different on Jan. 1, even if it keeps the same name. The good news: the protections that matter most to cancer patients, including the ban on denying coverage for pre-existing conditions, remain in place.
What We Know
- Marketplace plans cannot deny coverage or charge more because of a cancer diagnosis or history.
- The 2027 out-of-pocket maximum is $12,000 for one person and $24,000 for a family, up from $10,600 and $21,200.
- KFF reports average benchmark silver premiums rise 13% in 2027, after 26% in 2026.
- The American Cancer Society projects about 2,114,850 new cancer diagnoses in the U.S. in 2026.
What Is Still Unclear
- How many marketplace enrollees are in active cancer treatment is not published in federal data.
- Exact 2027 networks and drug lists vary by plan and can change during the year.
- Pending lawsuits over marketplace rules could affect future enrollment rules.
- Whether Congress will restore enhanced subsidies before enrollment closes.
Why Cancer Patients Feel Every Change in Their Plan
The scale of the problem is large. The American Cancer Society projects about 2,114,850 new cancer diagnoses and 626,140 cancer deaths in the U.S. in 2026. The good news in the same report: the five-year relative survival rate for all cancers combined has reached 70%, and cancer death rates have fallen 34% since their 1991 peak. More people are living for years after a diagnosis, which means more people need insurance that keeps paying for scans, follow-up visits and maintenance drugs long after active treatment ends.
Money is already tight for many of these patients. In a 2024 survey of more than 1,200 cancer patients and survivors by the American Cancer Society Cancer Action Network, about 47% reported medical debt, and nearly half of those owed more than $5,000, KFF Health News reported. In a December 2025 survey, the same group found that nearly three in four patients and survivors who rely on the marketplace said losing the enhanced tax credits would threaten their access to care. Those credits expired at the start of 2026.
What Cancer Patients and Survivors Report About Costs
Your Oncologist and Your Drugs Come Before the Premium
The two questions that matter most are simple: can I keep my doctors, and does this plan cover my drugs at a price I can afford? CURE’s 2027 enrollment guide puts both at the top of its list. Marketplace plans, especially lower-cost ones, often use narrow networks. A plan may include a local hospital but exclude the academic cancer center where you get treated. Being out of network can mean paying the full bill.
Search the Directory by Name, Then Call
Check each 2027 plan’s directory for your oncologist, your surgeon, your radiation oncologist and the hospital or infusion center itself. Then confirm by phone with both the insurer and the cancer center, because directories can be wrong. Many cancer centers have financial counselors who know which marketplace plans they accept for the coming year. Ask them before you enroll, not after the first claim is denied.
Drug Lists Are Where Cancer Costs Hide
Every plan has a formulary, the list of drugs it covers, sorted into cost tiers. Cancer drugs, including many taken as pills at home, are often on the highest specialty tier, where patients pay a percentage of the price rather than a flat copay. The Hematology/Oncology Pharmacy Association says patients can face 25% to 33% of the drug’s cost, with specialty-tier charges of $2,000 to $7,000 a month. Check every medicine you take, including anti-nausea drugs, pain medications and drugs for side effects.
The Yearly Cap and the Metal Level Decide Your Real Cost
The out-of-pocket maximum is the most you pay in a year for covered, in-network care, counting deductibles, copays and coinsurance but not premiums. For 2027, federal rules cap it at $12,000 for one person and $24,000 for a family, up from $10,600 and $21,200 in 2026. Many plans set lower limits. For someone in active cancer treatment, where a single infusion or scan can cost thousands, this number is often more important than the deductible.
2027 Out-of-Pocket Limits That Can Apply to You
Metal levels describe how costs are split. A bronze plan pays about 60% of average covered costs, silver about 70%, gold about 80% and platinum about 90%. If your income is under 250% of the poverty level, a silver plan comes with cost-sharing reductions that raise its value and lower deductibles. These extra savings are only available on silver plans, which is why lower-income cancer patients should compare silver carefully before choosing a cheaper bronze plan.
Share of Average Costs the Plan Pays, by Plan Type
Gold Can Cost Less Than You Expect
Because of how insurers price silver plans, gold plans are sometimes surprisingly affordable. Analyst Andrew Sprung reports that in 21 states the average lowest-cost gold plan is priced below the benchmark silver plan for 2027. KFF’s national averages for a 40-year-old show the cheapest gold plan at $694 a month before subsidies, below the $703 benchmark silver. For people above 250% of the poverty level who expect heavy medical use, a gold plan deserves a close look.
Prior Authorization, Clinical Trials and the Fine Print
Cancer treatment often needs approval before it happens. Ask each plan which of your services require prior authorization: infusion drugs, PET and MRI scans, radiation, genetic testing and specialty pharmacy drugs are common examples. CURE’s guide recommends checking this before enrolling. A new plan may require fresh approvals for treatment you already started, so ask about transition or continuity-of-care policies too.
Clinical Trial Costs Are Protected by Law
Federal law requires most non-grandfathered health plans, including marketplace plans, to cover routine patient costs for people enrolled in approved clinical trials for cancer and other life-threatening conditions, under 42 U.S.C. 300gg-8. Insurers cannot deny you coverage for joining a trial. The plan does not have to pay for the experimental drug itself or for data collection, and it can require in-network providers when they take part in the trial. If you are considering a trial in 2027, ask the trial team which plans they have worked with.
Make Sure Your Income Estimate Reflects Treatment
Premium tax credits are based on your expected 2027 household income, not last year’s tax return. Cancer often reduces work hours or forces unpaid leave, which can lower income and raise your subsidy. CURE’s guide recommends updating your income if treatment has cut your hours. For 2027, the IRS sets the most you pay for the benchmark plan at 2.15% to 10.22% of income, depending on where you fall relative to the poverty level. Above 400% of the poverty level, $63,840 for a single adult, there is no premium help at all.
| Household income, single adult | Poverty level | Most you pay for benchmark | Extra help to look for |
|---|---|---|---|
| Below $21,227 | Under 133% | 2.15% of income | Medicaid in expansion states |
| $21,227 to $31,920 | 133% to 200% | Up to 6.78% | Silver CSR, 87% to 94% value |
| $31,920 to $39,900 | 200% to 250% | Up to 8.66% | Silver CSR, 73% value |
| $39,900 to $63,840 | 250% to 400% | Up to 10.22% | Compare gold and silver |
| Above $63,840 | Over 400% | Full price | State subsidies in some states |
Income bands are calculated from the 2026 federal poverty guideline of $15,960 for one person, which is used for 2027 coverage, and percentages come from IRS Revenue Procedure 2026-26 as summarized in published guides. Medicaid eligibility at 138% of poverty applies in states that expanded the program. If your income drops because of cancer, you can apply for Medicaid at any time of year, not just during open enrollment.
A Tax-Time Warning for 2026 Coverage
KFF notes that caps on repaying excess premium tax credits were eliminated starting with the 2026 tax year. If your 2026 income ended up higher than you estimated, perhaps because you returned to work after treatment, you could owe the full difference when you file in early 2027. Report income changes to the marketplace during the year to avoid a large tax bill.
The Dates That Protect Your Coverage
HealthCare.gov open enrollment runs from Nov. 1, 2026, to Jan. 15, 2027, CMS says. Choose a plan by Dec. 15 for coverage that starts Jan. 1. Plans chosen Dec. 16 through Jan. 15 start Feb. 1, according to CURE. For someone in treatment, a one-month gap can mean postponed care or full-price bills, so the Dec. 15 date matters most. States that run their own marketplaces set their own deadlines.

Frequently Asked Questions
Can an ACA plan deny me coverage because I have cancer?
No. Marketplace plans cannot refuse coverage or charge higher premiums because of cancer or any other pre-existing condition. Short-term and other non-ACA plans can.
What is the ACA out-of-pocket maximum for 2027?
The 2027 limit is $12,000 for one person and $24,000 for a family, up from $10,600 and $21,200. Many plans set lower limits, and premiums do not count toward it.
When is the deadline to enroll in an ACA plan for 2027?
On HealthCare.gov, choose a plan by Dec. 15 for coverage starting Jan. 1. Enrollment ends Jan. 15, 2027, with coverage starting Feb. 1. Some states have later deadlines.
How do I know if my cancer drug is covered?
Look up the plan’s 2027 formulary, or drug list, before enrolling. Check the tier, whether it needs prior authorization and whether it must come from a specialty pharmacy.
Do ACA plans cover cancer clinical trials?
Most marketplace plans must cover routine patient costs in approved clinical trials for cancer under federal law. They do not have to pay for the experimental treatment itself.
Is a gold or bronze plan better for someone with cancer?
It depends on your expected costs. People likely to reach the out-of-pocket maximum often pay less overall with a lower cap, even with a higher premium. Compare premiums plus the cap.
What if my income dropped because of cancer treatment?
Update your income estimate on the marketplace. You may qualify for larger tax credits, silver plan cost-sharing reductions or Medicaid, which you can apply for any time.
What if I miss the open enrollment deadline?
You generally need a special enrollment period, such as losing job-based coverage or moving. Medicaid applications are accepted year-round.
The Short Version for Cancer Patients
For 2027 marketplace coverage, start with your doctors and drugs, not the premium. Confirm your oncologist and cancer center are in network, check each drug’s tier and prior authorization rules, and compare plans by a year of premiums plus the out-of-pocket maximum, which can reach $12,000. Look at gold and cost-sharing silver plans, update your income if treatment changed it and avoid non-ACA plans that can exclude cancer. Enroll by Dec. 15 for Jan. 1 coverage; HealthCare.gov closes Jan. 15.
