Open Enrollment Explained

Open Enrollment: Dates and Strategy

The annual window

Open enrollment for marketplace plans generally runs from November 1 to mid-January, with exact dates varying by state. Enroll by mid-December in most states and coverage starts January 1.

Missed it? You may still have a path

Qualifying life events open a 60-day special enrollment period any time of year: losing other coverage, marriage, a new baby, a move to a new coverage area, and more. Certain private plans also enroll year-round.

How to use the window well

• Do not auto-renew blindly. Networks, drug lists, and prices change every year.
• Update your income estimate so your subsidy is right.
• Re-verify your doctors, because networks shift annually.

We run this checklist with every client each fall, and it routinely finds savings.

What to have ready before you enroll

Having a few details on hand makes enrollment faster and reduces the chance of a correction later. Before you start, gather:

• An income estimate for the coming year for everyone on the application, since subsidy eligibility is based on projected income rather than last year's.
• Names and dates of birth for each person who needs coverage.
• A list of the doctors and facilities you want to keep, including specialists.
• Current prescriptions with dosages, because drug lists differ between plans and between years.
• Details of any coverage you have now and the date it ends.

What happens if you do nothing

If you already have a marketplace plan and take no action, you will usually be re-enrolled automatically into the same plan or, if it is discontinued, into one the marketplace considers similar. That sounds convenient, but it carries real risk. Your premium may change, your subsidy is recalculated using old income information, and your doctors or medications may no longer be covered the same way. Automatic re-enrollment protects you from having no coverage at all; it does not protect you from being in the wrong plan.

Proving a special enrollment period

If you are enrolling outside the annual window because of a qualifying life event, expect to document it. The marketplace commonly asks for proof such as a letter showing the date prior coverage ended, a marriage certificate, a birth certificate, or evidence of a move. Submitting documentation promptly matters, since coverage can be delayed or reversed if a request goes unanswered. Our team can tell you what is typically requested for your situation before you apply.

Timing your coverage start date

Enrollment date and coverage start date are not the same thing. In most states, enrolling by mid-December means coverage begins January 1, while enrolling between mid-December and the close of the window generally means coverage begins February 1. If you are timing a procedure, a prescription refill, or the end of an employer plan, that difference is worth planning around rather than discovering afterward.
