Family Coverage Is a Different Sport
Insuring a household of four requires different thinking than covering one adult. Deductibles work differently, network breadth matters more (kids, spouse, and yourself may all see different doctors), and the total annual cost can swing by thousands based on how you structure coverage.
Embedded vs Aggregate Family Deductibles
Embedded: Each family member has their own individual deductible, and there's a family maximum. If one child needs surgery, they only need to hit their individual deductible before the plan kicks in for them — even if the family deductible isn't met yet. Friendliest structure when one member has heavy use.
Aggregate: The whole family shares one combined deductible. No individual sub-deductibles. Better if the family is generally healthy and expects to hit the whole deductible together or not at all.
When to Split Coverage Across Plans
Two situations where splitting saves money:
- Employer plan is affordable for the employee, expensive for dependents. Keep the employee on the group plan and put the rest of the family on a Marketplace or private PPO plan. Check ACA "family glitch" rules — they were updated in 2023 to make more families subsidy-eligible.
- One spouse is self-employed. Often a hybrid works: employer plan for one, self-employed tax-deductible individual coverage for the other.
Kids, College, and Aging Off
Under 26, a child can stay on a parent's plan. But "on the plan" doesn't always mean "well covered" — a college kid at school out of state may need a plan with a broader network or a student policy that covers the university health center. If the parent plan is a narrow HMO, the child at college may need something different.
When they hit 26, aging off is a qualifying life event that opens a Special Enrollment Period. Read the Special Enrollment Periods guide for the playbook.
Life Events That Change Coverage
- New baby — 60-day SEP, add coverage retroactive to birth.
- Marriage — 60-day SEP; you can restructure coverage across the household.
- Divorce — if it triggers loss of coverage, opens a SEP.
- Move to a new coverage area — opens a SEP; new carriers may be available.
- Adult kid aging off at 26 — opens a SEP for that dependent.
