How to Renew Health Insurance in 2026

Your plan type (ACA Marketplace, employer-sponsored, Medicare or Medicaid) determines your 2026 deadline and where to act. ACA Marketplace open enrollment closed Jan. 15, 2026; the next window opens Nov. 1, 2026. Medicaid accepts new enrollees year-round with no deadline.

Before renewing, check whether your current plan still fits your 2026 needs. ACA Marketplace plan premiums rose an average of 20% in 2026, per MoneyGeek's analysis of CMS rate filings. Compare plans before auto-renewing. 

• Premium: Confirm your 2026 monthly premium and compare it against available plan options. Health insurance costs vary by plan type, insurer and location.
• Provider network: Verify your doctors and preferred hospitals are in your plan's 2026 network before renewing. Out-of-network care can cost 40% to 60% more, even with insurance.
• Drug formulary: Check that your prescriptions appear on your plan's 2026 formulary and review tier assignments for each prescription. Tier changes affect what you pay at the pharmacy.
• Deductible and out-of-pocket maximum: Note any changes to your 2026 cost-sharing structure. For Medicare beneficiaries, also review what Medicare covers and doesn't cover to confirm any supplemental coverage fills remaining gaps.
• Premium tax credit eligibility: Update your Marketplace application. Enhanced federal subsidies are no longer available in 2026, per HealthCare.gov. Reporting income or household changes may affect what you owe monthly.

The right comparison tool depends on your plan type. HealthCare.gov, medicare.gov/plan-compare and state Medicaid portals each serve a dedicated coverage pathway.

• ACA Marketplace: Use HealthCare.gov's plan comparison tool to review premium, deductible, network, drug formulary and out-of-pocket max, or explore MoneyGeek's best health insurance guides.
• Employer plans run through your HR portal or benefits administrator. Check what your employer contributes, whether the plan is HSA-eligible and how the premium is split.
• Medicare Advantage and Part D: Use the Medicare Plan Finder at medicare.gov/plan-compare or review the MoneyGeek Best Medicare Advantage guide. Prioritize star ratings and drug formulary coverage, then compare premium and out-of-pocket limits.
• Medicare Supplement (Medigap): Focus on Plan G, N and F, and pay attention to pricing method. Community-rated plans hold costs steadier than attained-age plans as you get older. Compare Top Medicare Supplement Plans.
• Medicaid: Go to Medicaid.gov or your state agency portal to confirm income eligibility, covered services and available managed care plan options.

Once you've compared ACA Marketplace, Medicare or Medicaid options, take action before your enrollment deadline. These steps apply across all plan types, with portal differences noted earlier.

1. Log in to your enrollment portal: HealthCare.gov for ACA Marketplace, medicare.gov/plan-compare for Medicare, your HR system for employer plans or your state Medicaid portal for Medicaid.
2. Update all household, income and coverage details: Outdated information can affect your subsidy amount or plan eligibility. Review every pre-filled field before submitting.
3. Submit your enrollment and pay your first premium: Pay your insurer directly, not the Marketplace. Coverage doesn't start until your insurer receives your first payment.
4. Save your confirmation: Keep your enrollment confirmation number and a copy of your Summary of Benefits and Coverage as proof of active coverage.

After enrolling in your ACA Marketplace, Medicare or Medicaid plan, confirm your coverage is active before your next medical appointment or prescription fill.

• Check your insurance card: Your new ID card from your insurer confirms your plan is active. If you haven't received it within two weeks of your coverage start date, contact your insurer directly.
• Set a calendar reminder: The ACA Marketplace opens Nov. 1, 2026, and the Medicare Annual Enrollment Period opens Oct. 15, 2026. Mark both dates to review your plan before auto-renewal takes effect.
• Keep your confirmation: Save your enrollment confirmation number and your Summary of Benefits and Coverage in case of billing questions or coverage disputes.

A Special Enrollment Period lets ACA Marketplace enrollees sign up or switch plans outside open enrollment if a qualifying life event occurred in the past 60 days, per HealthCare.gov. Most SEP windows run 60 days from the triggering event. Qualifying life events include:   

• Job loss or loss of job-based coverage: You have 60 days from your coverage end date. A letter from your employer or insurer confirming when coverage ended is required.
• Marriage: You have 60 days from the marriage date. Submit a marriage certificate to verify the event.
• Birth or adoption: You have 60 days from the birth or adoption date. A birth certificate or adoption papers are required.
• Permanent move to a new coverage area: You have 60 days from the move date. Provide proof of your prior and new address, such as a utility bill or signed lease.
• Loss of Medicaid or CHIP eligibility: You have 60 days from the loss date. Submit the notice from Medicaid or CHIP confirming the end of your eligibility.
• Release from incarceration: You have 60 days from your release date. Documentation from the correctional facility is required.

Medicaid accepts applications year-round from income-eligible households. No open enrollment period is required. In states that expanded Medicaid under the ACA, eligibility extends to adults with income up to 138% of the federal poverty level. Nine states have not expanded Medicaid. Check eligibility and apply at Medicaid.gov or through your state Medicaid agency.

COBRA lets you keep your employer's health plan for up to 18 months after losing job-based coverage, and up to 36 months in certain circumstances. You pay the full premium, including your employer's previous share, plus a 2% administrative fee. You have 60 days from your coverage end date to elect COBRA. Because you bear the full cost, COBRA is usually more expensive than an ACA Marketplace plan with premium tax credits.

• Catastrophic health plans are available to adults under 30, or those with a hardship or affordability exemption granted by the Marketplace at HealthCare.gov. Health insurance for adults in this gap also includes Marketplace options with premium tax credits, depending on income. 

• Short-term health plans cost less than ACA plans but don't meet ACA minimum essential coverage standards and can exclude pre-existing conditions. Use short-term coverage only as a temporary bridge to comprehensive coverage.
