What Blue Cross Blue Shield Is

Blue Cross Blue Shield is not a single insurance company — it is a network of independent health insurance companies that operate under the Blue Cross Blue Shield brand. Each state has its own Blue Cross Blue Shield plan, and they are run by different organizations. When you buy a Blue Cross Blue Shield plan, you are buying from the local company in your state, not from a national headquarters.

The plans cover doctor visits, hospital stays, prescription drugs, and preventive care. What you pay and what the plan covers depends on which specific plan you choose and which state you live in. Blue Cross Blue Shield plans are available through your employer, through the individual marketplace (Healthcare.gov or your state's marketplace), or through Medicare and Medicaid programs.

Key Takeaways

  • Blue Cross Blue Shield is a federation of independent state-based insurers, so your plan and costs depend on which state you live in and which specific plan you choose.
  • You can get a Blue Cross Blue Shield plan through your employer, the individual marketplace, Medicare, or Medicaid — the route you use determines your costs and enrollment windows.
  • Every plan has a deductible (what you pay before insurance kicks in), copays (fixed amounts per visit), and coinsurance (a percentage of costs you share with the insurer).
  • Blue Cross Blue Shield plans come in different metal levels — Bronze, Silver, Gold, and Platinum — which determine how much you pay upfront versus how much the plan pays.
  • You can only change plans during open enrollment periods or if you have a may have access to life event like losing other coverage or moving to a new state.

How to Find and Compare Blue Cross Blue Shield Plans

If you are looking for coverage on your own (not through an employer), you start at Healthcare.gov or your state's health insurance marketplace. Enter your zip code and income, and the site will show you all available plans in your area, including Blue Cross Blue Shield options. Each plan displays its monthly premium, deductible, and what you will pay for common services like a doctor visit or hospital stay.

The marketplace also shows you whether you may be able to reduce your monthly premium through tax credits, which are based on your income. These credits lower what you pay each month. You can compare plans side by side to see which one fits your budget and health needs. Open enrollment for individual marketplace plans runs from November through January each year, though dates vary slightly by state.

If your employer offers Blue Cross Blue Shield, you will receive plan documents during your company's open enrollment period (usually once a year). Your employer will show you the monthly cost, what the plan covers, and your out-of-pocket limits. You can choose to enroll, decline, or switch to a different plan offered by your employer during that window.

Understanding Premiums, Deductibles, and Out-of-Pocket Costs

Your premium is what you pay every month for coverage, whether you use the plan or not. This amount is set when you enroll and does not change until the next enrollment period. If you get a plan through the marketplace, you may pay the full premium yourself. If you get it through an employer, your employer typically pays part of the premium and you pay the rest through payroll deduction.

Your deductible is the amount you must pay out of your own pocket for covered services before your insurance plan starts to pay. For example, if your deductible is $1,500, you pay the first $1,500 of your medical bills, and then the plan begins to share costs with you. Deductibles reset every January. Some preventive services (like annual checkups and vaccines) are covered without meeting your deductible.

After you meet your deductible, you typically pay a copay (a fixed dollar amount, like $25 for a doctor visit) or coinsurance (a percentage of the cost, like 20 percent). Your plan also has an out-of-pocket maximum — once you reach this amount in a year, the plan pays 100 percent of covered costs for the rest of that year. Out-of-pocket maximums vary by plan but are set by federal law.

Metal Levels: Bronze, Silver, Gold, and Platinum

Marketplace plans are sorted into four metal levels, which describe how costs are split between you and the plan. A Bronze plan has the lowest monthly premium but the highest deductible and out-of-pocket costs — you pay more when you use care. A Silver plan sits in the middle for both premium and out-of-pocket costs and is the most common choice on the marketplace.

A Gold plan has a higher monthly premium but lower deductibles and out-of-pocket costs — you pay more upfront but less when you need care. A Platinum plan has the highest premium but the lowest deductible and out-of-pocket costs. The metal level does not indicate quality of care; all plans must cover the same essential health services. Your choice depends on whether you expect to use a lot of medical care (Gold or Platinum) or rarely use care (Bronze).

If your income is between 100 and 400 percent of the federal poverty level, you may be able to reduce your costs through tax credits and cost-sharing reductions, which lower your out-of-pocket expenses. Silver plans often offer the best value for people who receive these reductions.

Using Your Blue Cross Blue Shield Plan

When you enroll in a Blue Cross Blue Shield plan, you receive an insurance card (either physical or digital through a mobile app) that shows your member ID, group number, and customer service phone number. You present this card when you visit a doctor, go to the hospital, or fill a prescription. The provider checks whether you are covered and what you will owe.

Blue Cross Blue Shield plans have a network of doctors, hospitals, and pharmacies that have agreed to accept the plan's rates. If you use an in-network provider, you pay the lower copay or coinsurance amount shown in your plan. If you use an out-of-network provider, you typically pay more — sometimes significantly more — and may have to pay upfront and request reimbursement later.

You can find in-network providers by logging into your Blue Cross Blue Shield account online or calling the customer service number on your card. Most plans also have a mobile app where you can search for providers, view your claims, and check your deductible progress. If you need a specialist, some plans require you to get a referral from your primary care doctor first.

What Happens When You Change Jobs or Move

If you lose employer coverage because you change jobs, you have 60 days to enroll in a new plan without waiting for the annual open enrollment period. This is called a may have access to life event. You can enroll in a Blue Cross Blue Shield plan through the marketplace during this window. You will need to provide proof that you lost coverage, such as a letter from your former employer or COBRA notice.

If you move to a different state, your current Blue Cross Blue Shield plan will end because each state has its own separate Blue Cross Blue Shield company. You have 60 days to enroll in a new plan in your new state. You can compare Blue Cross Blue Shield options in your new state on the marketplace or through your new employer if you have one.

If you turn 65, you become may be able to access for Medicare and should enroll during your initial enrollment period (which starts three months before your 65th birthday). Some people keep a Blue Cross Blue Shield supplemental plan (called Medigap) alongside Medicare to cover costs that Medicare does not pay.

Frequently Asked Questions

Can I use my Blue Cross Blue Shield plan in another state?

No. Each state has its own Blue Cross Blue Shield company, and your plan only works in your home state. If you travel, you can use out-of-network benefits, but you will pay higher costs and may need to pay upfront and request reimbursement. If you move permanently to another state, your plan ends and you must enroll in a new Blue Cross Blue Shield plan in that state.

What is the difference between Blue Cross and Blue Shield?

Historically, Blue Cross covered hospital care and Blue Shield covered doctor and surgical services. Today, most Blue Cross Blue Shield plans cover both, and the distinction is mostly historical. When you enroll in a Blue Cross Blue Shield plan, you are getting one integrated plan that covers both hospital and outpatient care.

Do I have to use a doctor in the network?

You do not have to, but using an in-network doctor costs you less. If you use an out-of-network provider, you pay a higher copay or coinsurance, and you may have to pay the full bill upfront and request reimbursement. Some plans require a referral from your primary care doctor to see a specialist, even in-network.

How do I know if a doctor is in my Blue Cross Blue Shield network?

Log into your Blue Cross Blue Shield account online or use the mobile app to search for providers by name or location. You can also call the customer service number on your insurance card. The search results will show you which doctors and hospitals are in-network and what your copay or coinsurance will be.

What happens if I do not enroll during open enrollment?

If you do not enroll during the annual open enrollment period and you do not have other coverage, you cannot enroll until the next open enrollment period unless you have a may have access to life event like losing a job, moving, or having a baby. You can enroll in a plan outside open enrollment only if you meet specific conditions.
