As for the public insurance, NJ only has NJ FamilyCare and Medicaid. For NJ FamilyCare, you need to have no insurance for 3 months. If you require ongoing treatment, of course you can't go without insurance for 3 months, then of course they won't cover you. NJ FamilyCare don't cover pregnant woman. Pregnant women are told to apply for Medicaid, which has very low income limit. CA has much better system. Like me, DH unemployed, can't afford COBRA ($1,100), FamilyCare denied me because I am pregnant. Both NY and PA has program just for pregnant woman, and NJ only has Medicaid.
As for private insurance, it's a guarantee acceptance program, therefore the premiums are very high, and only 6 or 7 companies are willing to sell individual plan, other companies intentionally price themselves out. Although it's guarantee acceptance program, you need to keep yourself covered and have no lapse in coverage for longer than 31 days, or else they won't cover for pre-existing condition. You can see the current rates, which may give you a heart attack.
Individual Health Coverage Program Rates
Of course if you keep yourself covered, you can't be eligible for NJ FamilyCare.
So if you lose your group plan, and you are not careful by keeping yourself covered, you can see how you can get stuck in between, not qualify for anything (public or private).
Many people here work just for the benefits.
For healthcare, it's no secret that both NY and PA have better hospitals.
California dreaming.......
