The calendar rules everything

Every date that decides the plan year

Health insurance is one of the few products where the deadline is more binding than the price. Miss January 15 without a qualifying life event and the next ordinary chance to enrol is eleven months away.

The plan year, in order

From rate filing to reconciliation

The consumer-facing part of the year is eleven weeks long. The rest of it is carriers, regulators and agents preparing for those eleven weeks.

  1. Apr - May

    Carriers

    Rate filings

    Carriers file proposed rates and plan designs with state regulators for the following plan year.

  2. Jun - Aug

    Regulators

    Rate review

    State departments of insurance review and often reduce proposed increases. Filings become public.

  3. Sep

    CMS

    Landscape files

    Plan and rate landscape files are published. Our index is rebuilt within 48 hours of release.

  4. Aug - Oct

    Annual CMS Marketplace training and the two agent-broker agreements must be completed before Nov 1.

  6. Dec 15

    Consumers

    January 1 deadline

    Enrol or change plans by this date for coverage effective January 1. The busiest single day of the year.

  7. Dec 16 - Jan 15

    Consumers

    Enrolments completed in this stretch take effect February 1, leaving a one-month gap.

  8. Jan 15

    The federal window closes. After this, only a qualifying life event opens a special enrollment period.

  9. Jan 31

    The Marketplace statement for the prior plan year is issued to every enrolled household.

    Advance premium tax credits are reconciled against actual income on IRS Form 8962.

  11. All year

    Qualifying households

    Special enrollment

    Marriage, birth, a move, or loss of other coverage opens a 60-day window at any point in the year.

Not everywhere is the same

State-based exchanges set their own dates

Seventeen states and the District of Columbia run their own marketplace. Several of them keep enrollment open past the federal deadline, which is the single most useful piece of information for anyone who missed January 15.

Illustrative selection. Confirm against your own state exchange each plan year.

A household that misses the federal deadline should check whether their state runs its own exchange before assuming the year is closed.1

Outside the window

What still opens a door after January 15

Special enrollment is not a loophole. It is the part of the statute that acknowledges that lives change in February.

Qualifying life eventWindowCoverage starts
Loss of job-based coverage60 days before and afterFirst of the following month
Marriage60 days afterFirst of the following month
Birth or adoption60 days afterDate of the event
Permanent move60 days afterFirst of the following month

Divorce with loss of coverage60 days afterFirst of the following month
Gaining lawful presence60 days afterFirst of the following month
Income change to under 150% FPLMonthly, where availableFirst of the following month

Voluntarily dropping other coverage does not open a special enrollment period, and neither does changing your mind about a plan already chosen.

For agents

Your own deadlines, which nobody sends you

An agent's calendar runs about ten weeks ahead of the consumer's. Everything that matters happens before November 1.

How the platform gates these
  • August

    CMS Marketplace training opens

    Complete it early. The queue in late October is the reason agents miss Nov 1.

  • September

    Landscape files publish

    Rebuild your quoting index and re-check every carrier's footprint for exits.

  • October

    Appointments and licences verified

    Resident and non-resident, per carrier, per state, with expiry dates recorded.

  • October 15

    Renewal book triaged

    Rank by exposure: benchmark moves, discontinued plans, credit falls. Call in that order.

  • February

    Commission reconciliation

    Match January statements against the book. Chase every policy in force and unpaid.

Put the dates somewhere you will see them.

Or let the desk do it. Households on our book get reminders before December 15 and before January 15, and nothing else.
