Special Enrollment Period Verification: What to Prepare Before You Enroll
If you enroll through a Special Enrollment Period, the Marketplace may ask you to prove the life event. Here is the deadline, how to send proof, and which rules CMS describes as temporary.
Quick answer
Keep documents that prove your qualifying event and its date. After you choose a plan through a Special Enrollment Period, HealthCare.gov gives you 30 days to send documents confirming your eligibility. If you cannot get a document, you can send a letter of explanation. Missing a deadline can mean losing coverage or savings.
The clocks that apply
| Step | Window | Source |
|---|---|---|
| Choose a plan after a qualifying event | Generally 60 days (90 days for Medicaid or CHIP loss) | HealthCare.gov |
| Choose a plan before a known coverage loss | Up to 60 days before it ends | HealthCare.gov |
| Send Special Enrollment Period documents | 30 days after choosing a plan | HealthCare.gov |
| Resolve an income inconsistency | 90 days from the notice | HealthCare.gov |
| Confirm citizenship or immigration status | 95 days from the notice | HealthCare.gov |
How to send documents
Log into your Marketplace account, open your application details and upload the documents for each item. HealthCare.gov also accepts mailed photocopies. Uploads must be in common file types and under 10 MB. Submit documents even if you miss a deadline, because you might still re-qualify for savings or coverage.
Which rules are temporary?
CMS's 2025 final rule requires the federal platform to verify Special Enrollment Period eligibility before enrollment for at least 75% of new Special Enrollment Period enrollments, beginning with plan year 2026. CMS lists that provision, along with the repeal of the monthly 150% poverty-level Special Enrollment Period, as ending after the 2026 plan year. Do not assume it applies, or has ended, for your 2027 enrollment: check the current HealthCare.gov rules when you apply. The Open Enrollment change, by contrast, is permanent from 2027 on.
What to gather by event
- Lost coverage: a notice showing the end date and who was covered.
- Move: proof of the new address and the date you moved.
- Marriage, birth or adoption: the document that shows the date of the event.
HealthCare.gov publishes the exact list of acceptable documents for each event, and that list controls what is accepted.
