Common healthcare terms and FAQ
The terms and acronyms for "health insurance" or "health coverage" can be confusing. Here are some common words to know as you explore coverage options.
Frequently asked questions (FAQs)
What is the Advanced Premium Tax Credit? How do I qualify?
Advanced Premium Tax Credit (APTC), also called a subsidy, is federally funded financial assistance for health plan premiums. For those who are eligible, it sets a limit on how much one pays based on a percentage of their annual income. The amount of premium assistance that one can qualify for depends on age, household income and size, and the cost of affordable health care coverage in their region. Premium assistance is only available for medical plans purchased through Covered California
A simple way to find out if you may qualify is by using our subsidy calculator. If you learn that you may be eligible, contact your broker to see your options. You can also contact us at (888) 273-0010.
What do I pay monthly?
You’ll pay a fixed monthly rate for your health insurance policy. The amount depends on the plan you choose, where you live, and the age of each person on the plan. The lower your plan’s monthly rate, the more you typically pay when you see the doctor, and vice versa. Identifying how often you see a doctor can help you choose the right plan for you.
Depending on your household size and income, you may be eligible for financial assistance through Covered California to lower your plan’s monthly rate or even your costs for medical care.
How much will I pay when I see a doctor?
Your cost will depend on the services provided and your plan’s benefits. Here's how it works:
- Some services have a copay (a fixed dollar amount).
- Some services will be subject to a deductible, which is the amount of money you pay for services before Blue Shield starts to pay a share of the costs.
- Once you have met your deductible, you will pay a coinsurance. That's a fixed percentage of the bill (Blue Shield will pay the rest of the charges for your visit).
- To protect you and your family from unexpected costs, most plans have an annual out‑of‑pocket maximum. Once you reach the out-of-pocket maximum, your health plan covers 100% up to the allowed charges for most covered medical services.
What is the tax penalty for not having health coverage in California?
Having continuous coverage ensures you have access to care when you need it and protects you from unexpected healthcare costs, among other benefits. Having health coverage also helps you avoid the California tax penalty.
In other words, if you do not have health coverage, you may have to pay more in taxes.

What is the California tax penalty?
Those who choose to go without coverage may be subject to a penalty as part of their annual state tax filing if they have access to affordable coverage within the cost limitations set by the state. There can be penalties of up to nearly $2,700 per family, which is based on 2.5 percent of household income or a minimum of $900 per adult and $450 per dependent child under 18 in the household, whichever is greater. The California Franchise Tax Board, which administers the state mandate, will assess the penalties for the coverage year when consumers file their taxes.
Californians can file for an exemption due to financial or other hardship. To learn more, visit Covered California or the California Franchise Tax Board.

Coinsurance
A fixed percentage of the cost of your services that you’re responsible for. This is usually after you’ve met your deductible.
Copayment
