Step-by-step
- 1
Enrol in your employer's plan within the new-hire window
Typically 30 days from your start date. Compare the deductible and out-of-pocket maximum, not just the premium. In a region this large, also check the network's geographic coverage — an HMO that works on the Westside may have thin options in the Valley.

Without an employer plan, use Covered California
California runs its own exchange rather than HealthCare.gov, and typically operates a longer open-enrolment window than federally-run states. Check current dates on the site rather than assuming the federal deadline.

Check Medi-Cal eligibility first
California expanded Medi-Cal further than most states, including full-scope coverage regardless of immigration status for all age groups. Newcomers on modest early incomes frequently qualify and never check because they assume US healthcare is unaffordable by definition.

Register with a primary care physician near where you live
Your PCP gates specialist access in most plans, and in a county this spread out, a doctor twenty miles away is a doctor you will not visit. Confirm network status with the practice directly — insurer directories are frequently wrong.

Learn the urgent care versus emergency room distinction
An ER visit for something a clinic could treat can cost thousands even insured. Urgent care handles fractures, stitches and infections far more cheaply. Find your nearest and save it now.

Know the county system exists
LA County Department of Health Services runs public hospitals and clinics providing care on a sliding scale regardless of insurance or immigration status. It is not a substitute for coverage, but it is a real safety net and one of the largest in the United States.

Things most newcomers don’t know
California levies its own penalty for going uninsured.
The federal individual mandate penalty went to zero in 2019, but California reinstated a state-level one. Going without minimum essential coverage produces a state tax penalty at filing. People who read that 'the US mandate was repealed' are caught by this every year.

Medi-Cal now covers all income-eligible adults regardless of immigration status.
California phased in full-scope Medi-Cal without an immigration-status requirement across all age groups. No other large state goes this far. For a family arriving on modest means, or with mixed status, this is materially different from Texas or Florida.

Check network geography, not just network membership.
Los Angeles County is 4,750 square miles. A plan can be technically in-network across it while every convenient specialist sits on the other side of the basin. Look at where the network's hospitals and clinics actually are relative to your home and work before choosing.

The deductible is what will surprise you, not the premium.
US plans commonly require you to pay the first several thousand dollars of care yourself each year. Someone from a national health service reads 'I have insurance' as 'I am covered', then receives a $2,800 bill for a scan.

Common mistakes to avoid
- Missing the 30-day new-hire enrolment window.
- Choosing on premium alone and meeting a five-figure deductible.
- Not realising California penalises going uninsured, unlike most states.
- Choosing a plan without checking where its network actually is across a very large county.
- Going to an emergency room for something urgent care handles.
