State law overrides the federal baseline in both directions: some states cap contracts shorter, and a handful prohibit the products entirely. Always confirm with the state insurance department before applying, because carrier filings change mid-year.
What this means for a coverage gap
If you are bridging a gap in California, line up the policy start date with the day your previous coverage ends — a one-day gap can turn a new diagnosis into a pre-existing condition.
- Confirm the carrier is actually filing rates in your county, not just the state.
- Check the network hospitals near you before paying the first premium.
- Keep proof of continuous coverage: it matters when you later apply for an ACA plan.
Cost expectations
At $180–$320 a month, a four-month bridge costs roughly 720 dollars in premiums plus the deductible if you claim. That total — not the headline monthly figure — is the number to compare against an ACA plan’s premium after any subsidy.
California allows up to Under 6 months (state limit) at around $180–$320 a month, with no renewal.
