Lost job-based coverage: Enrollment Windows and Coverage Start Dates
Lost job-based coverage: window = same rules as aca special enrollment; coverage varies — day after election. Both doors compared.

| Trigger event | Lost job-based coverage |
|---|---|
| Window | Same rules as ACA special enrollment |
| Coverage starts | Varies — day after election |
Job loss opens an ACA special enrollment window, but short-term plans have no window at all — you can buy one the day after layoffs with coverage starting tomorrow.
The deadline mechanics
| Parameter | Value |
|---|---|
| Trigger event | Lost job-based coverage |
| Window | Same rules as ACA special enrollment |
| Coverage starts | Varies — day after election |
ACA special enrollment gives same rules as aca special enrollment from the trigger — miss it and the marketplace door shuts until open enrollment. Short-term plans have no door to shut.
Short-term vs marketplace for this trigger
Run both quotes the same day. The marketplace plan is usually the better value after subsidies; the short-term plan is the faster, cheaper-looking, thinner option that starts tomorrow. The right answer depends on prescriptions and pre-existing conditions, not just premium.
Paperwork that speeds it up
- Get the termination or trigger date in writing — carriers and the marketplace both date the window from documents, not memories.
- For job loss: the benefits termination letter, not the last paycheck.
- For aging off a parent plan: the carrier’s end-date confirmation.
For lost job-based coverage: move within the window, and price both doors before choosing one.
