Health Coverage Deadlines

Fall marks the beginning of open enrollment season. Whether you purchase health insurance through the federal or a state Marketplace or receive coverage through Medicare, reviewing your options early can help you prepare for changes in premiums, deductibles, provider networks, prescription coverage, and other out-of-pocket costs.

Marketplace Open Enrollment

Federal Marketplace Open Enrollment for 2027 coverage runs from November 1, 2026, through January 15, 2027.

To have federal Marketplace coverage begin January 1, 2027, you generally need to enroll in or change plans by December 15, 2026. Selections made between December 16, 2026, and January 15, 2027, generally begin February 1, 2027.

Deadlines and effective dates may differ in states that operate their own Marketplaces, so confirm the rules that apply where you live. Outside Open Enrollment, you may generally enroll in or change Marketplace coverage only if you qualify for a Special Enrollment Period following an eligible life event.

Even if you are automatically re-enrolled, do not assume your existing plan remains the best fit. Premiums, deductibles, provider networks, prescription coverage, and available subsidies can change from year to year.

Medicare Open Enrollment

Medicare Open Enrollment runs from October 15 through December 7, 2026. Changes made during this period generally take effect January 1, 2027.

During Medicare Open Enrollment, eligible individuals can review and change Medicare Advantage or Medicare prescription drug coverage. Because plan premiums, formularies, pharmacies, provider networks, and out-of-pocket expenses may change annually, it is important to compare your current coverage with the options available for 2027.

Preparing for Enrollment

Before making a selection, gather your plan notices, medication list, preferred providers, anticipated healthcare needs, and estimated household income. Consider the complete cost of coverage—not just the monthly premium—including deductibles, copayments, coinsurance, and maximum out-of-pocket limits.

Health coverage decisions can also affect your broader financial plan. Review your options early, and consider how potential healthcare expenses fit into your retirement income, cash-flow, and tax-planning strategies. A licensed health insurance or Medicare professional can provide plan-specific guidance, while our team can help you evaluate the broader financial implications of your choices.
