How health insurance works, in a nutshell:

1. How health insurance works to cover the cost of medical services and treatments can be confusing for patients! Your final out-of-pocket costs depend on plan details like deductibles, copayments, and coinsurance requirements. Understanding these terms and responsibilities can help you anticipate costs.
2. When seeking care, make sure your insurance benefits include the provider and service. Confirm whether they’re in-network or out-of-network. (You’ll likely pay more for out-of-network care.) And work with your provider to find the lowest-cost medication available.
3. After your visit, your provider will file a claim with your insurance company for the service. Your insurer will assess and send you an Explanation of Benefits that details what they’ve paid and your financial responsibility. You may also receive a final bill from the provider for any remaining balance.

At Dr. B, we want to make quality online care accessible and affordable. So we’ve simplified the care process with $15 online consultations for common treatments. Then, we make it easy to use insurance coverage for any prescribed medications and offer a drug discount card to secure the lowest costs possible for self-pay patients.

To make consultation costs for our dynamic longevity programs even more affordable, we’re thrilled to now work in-network with major insurance companies. For covered patients, this can potentially reduce your out-of-pocket costs to your insurance copay!

But even with coverage, so many factors can affect your final care costs—and we understand how frustrating it can be to get an unexpected bill.

Knowledge is power. So in this article, we’ll explain how health insurance works, define the key terms that might affect your treatment costs, and outline the factors that contribute to you receiving a bill from Dr. B after we submit the consultation with your insurer.

What is health insurance—and why having it matters

Health insurance financially protects you from the high cost of medical care.

In the United States, health insurance is a cost-sharing arrangement. This means both you and your insurance provider pay specific amounts toward healthcare costs. These responsibilities are detailed in your health insurance plan, which specifies which services are covered (also called your benefits).

Cost-sharing responsibilities include:

• Premium: A fixed monthly amount you pay for the insurance plan.
• Copayments: Fixed amounts you’ll pay for services such as primary care visits, specialist visits, and prescriptions.
• Deductible: The amount you’ll pay out-of-pocket before your insurance covers a portion or all costs. This amount resets at the beginning of the year.
• Coinsurance: The percentage of a cost you’ll pay after you’ve met your deductible for different services or tools. For example, after you meet your deductible, you may not have to pay anything for a primary care visit, but you may have to pay 20% for a specialist visit.
• Out-of-pocket maximum: The most you’ll pay for in-network care through deductibles, copays, and coinsurance (not including your premium). After this, your plan will pay 100% for covered services. 
• Plan limits: After you’ve met your out-of-pocket maximum, federal law requires insurers to cover all essential health service costs—including hospitalizations, emergency care, and ongoing care for chronic conditions—no matter how high the total costs are. (This limit doesn’t apply to elective care services.)

Even with these responsibilities understood, a few additional factors affect how much a particular service (like a visit to a doctor) or treatment will cost you.

Important terms to understand regarding your insurance coverage include:

• Covered services/benefits: When you enroll in an insurance plan, you should receive a Summary of Benefits/Coverage document listing out the procedures, treatments and other services your plan agrees to pay for in part or in full. Understand your benefits to plan for your care and potential costs.
• Essential health benefits (EHB): Insurers are required under the Affordable Care Act (ACA) to cover 10 points of care, including preventative screenings, vaccines, annual checkups, medications and rehabilitative services. But these may then come with specific requirements. For example, screenings may be considered essential only after a certain age.
• Frequency limits for preventative care: Under the ACA, insurers must cover many preventive services and screenings at no cost to you. But plans can put limits on such care. For example, if you qualify for a cancer screening because of your age but you're not at high risk for that kind of cancer, your plan may not cover a physical and that screening within the same year.
• Plan exclusions: In the document detailing your benefits, you'll also find which services and treatments your plan does not cover. These are often those not deemed essential to health, like fertility treatments, cosmetic surgeries and medications prescribed off-label.
• Drug formularies: Most insurance plans organize medications in tiers, then assign the tiers different copay costs, with newer brand-name medications costing more than older or generic medications. If a medication you've been prescribed comes in a generic version, you can usually request it from your provider or pharmacist.
• Prior authorization: Some insurers require prior authorization for specific procedures and treatments (like GLP-1 weight-loss). This means your provider will submit documentation explaining why the treatment is medically necessary for you. The insurer will review the request (usually within 30 days, sometimes sooner) and send both you and the provider a document confirming approval or denial of the requested coverage. 
• The No Surprises Act: Passed in 2022, the new protections outlined in the act include requiring providers and facilities to give you an easy-to-understand estimate of potential care costs. So if you're not sure your insurance will cover a service or treatment, you'll at least have an idea of how much it could cost you if uncovered. (With Dr. B, we display potential self-pay costs on all treatment pages.)

What are the types of health insurance, and who qualifies for them?

In the United States, there are two types of health insurance: private and public.

Individual patients and business owners pay for private insurance plans. State and federal government programs fund public insurance plans.

Types of private health insurance include:

• Employer-sponsored insurance: Insurance you get through your job. Employers often pay a portion of the plan premium as a benefit, and the employee pays the rest. You do not get to choose your insurance company or plan, and you’re not required to accept insurance through your job.
• Health Insurance Marketplace plans: Anyone can purchase a private plan through the Health Insurance Marketplace, where you can review available insurers in your state and choose from a variety of plans. The federal government offers subsidies (or discounts) for plans to those whose income meets certain (lower) thresholds.

Types of public health insurance include:

• Medicare: This public program is available to people 65 or older and to younger disabled people. Patients may combine the 4 parts of care (such as services and prescriptions) to secure varying levels of coverage.
• Medicaid: Medicaid insures low-income individuals, including children, pregnant people, disabled people, and seniors. Both the state and federal governments fund it. Some disabled people may qualify for both Medicare and Medicaid coverage.
• The Veterans Health Administration: Members who served actively for 2 years (without a dishonorable discharge) can receive insurance through the Department of Veterans Affairs (VA). Benefits include routine care, specialist care, elder care, and other benefits. 

What are plan types, and how do they affect deductibles?

When choosing or signing up for private insurance, you’ll most likely see several plan types. These plans determine how much you’ll pay for specific providers.

If your provider or hospital is contracted with your insurer to offer services at a set price, they’re considered in-network. Providers and hospitals that haven’t contracted with your insurer are considered out-of-network.

• Exclusive provider organization (EPO): This plan covers only in-network services (except in an emergency). You don’t need a referral to see a specialist. But to secure a lower self-pay cost, you’ll want to confirm that each provider is in-network. This plan type may offer a lower premium and may include a deductible and coinsurance.
• Preferred provider organization (PPO): Similar to an EPO, this plan does not require referrals and largely covers in-network providers. It also covers a portion of out-of-network care (at a higher cost to you) and usually involves a deductible.
• Health maintenance organization (HMO): HMOs usually offer lower monthly costs and no-to-low deductibles. They cover only in-network providers, and you’ll need to select a primary care provider and get a referral to a specialist to access care. 
• Point of Service (POS): This less-common plan type requires a PCP and specialist referrals (like an HMO) but includes the option to pay more for out-of-network services (like a PPO). In-network benefits are usually not subject to a deductible, and their copays are low.
• High-deductible health plans (HDHPs): A high-deductible health plan means you’ll pay more out-of-pocket before coverage kicks in. But you can pair the plan with a Health Savings Account, which sets aside money for such expenses and reduces your taxable income. 

Why do billed amounts, allowed amounts, and self-pay amounts differ?

For a provider to become in-network with an insurance company, they must outline the cost of the services they provide. Each insurance company then sets the maximum it’ll pay for those services. Once an agreement is in place, the provider must bill all insured patients the same amount for each service.

When submitting a claim to a patient’s insurance company, the provider lists the services using a specific code that’s standardized across healthcare.

How much the insurer will pay—and the balance the patient might be responsible for—is determined by each insurance company’s agreed (or allowed) amount for each coded service.

Because administrative needs are greater when a patient uses insurance (meaning more people are submitting forms, tracking claims, calculating payments, etc.), the amount providers bill insurance companies is often higher than the amount they’d charge a patient without insurance.

Here’s a breakdown of cost amount terminology:

• Billed amount: The cost a provider charges an insurance company for a specific service, submitted via a CPT code.
• Allowed amount: The maximum amount the insurance company has agreed to pay for that service. For example, a provider may submit a service as costing $100. One insurance company may have agreed to pay $80 at most, while another company may have agreed to pay $60 at most. (This is sometimes also referred to as the negotiated rate.)
• Balance amount: This is what the patient owes based on their plan specifics, with factors like copays, deductibles, coinsurance, and out-of-pocket maximums determining cost-sharing responsibilities. For example, if the allowed amount is $80, the balance amount for a patient with a high-deductible health plan who hasn’t met their deductible may be the $80. Someone with no deductible or who has met it may pay a $30 copay, with the insurer covering the rest. 

Why can some medical costs differ when the care is the same?

CPT codes link to specific aspects of the care provided and how much the care costs.

Factors that go into that code and cost include:

• The level of medical expertise needed. For example, specialist care from neurologists or surgeons is usually more expensive than primary provider care. 
• The amount of time required. Longer visits for new patients, those that require records or lab work analysis, or patients needing medication changes take longer than brief refill consultations.
• Medication or procedure costs. For example, if a provider administers an injection, the code will link to the specific medication or vaccine injected. The procedure cost will vary depending on the equipment used and the team involved.

How to use health insurance and estimate out-of-pocket expenses

To understand your plan and potential out-of-pocket costs, first review your plan summary—a document sent to you by mail or email that outlines your entire plan. Most insurance companies also offer online access. Sign up online to access plan details, find in-network providers, estimate treatment costs, track a claim’s status, and more.

Otherwise, here’s what to expect during the treatment and insurance process.

1. Choose a provider—and find out whether they’re in- or out-of-network. With most plans, you’ll pay less if you see a provider who’s in-network with your insurer. If you’re seeking a new provider, you can usually choose from nearby in-network providers via your health insurance company’s website. If you have a provider in mind, you can search for them on that site, call your insurance company, or ask the provider’s office.
2. Book an appointment—and estimate the cost. Confirm that the service or treatment is a covered benefit—you’ll most likely pay more if it’s not. Look on your card for the copay amount for the type of service. If you haven’t met your deductible, expect to receive a bill for an amount outside of your copay. If you’ve reached your out-of-max, estimate that your insurance will cover the final cost.
3. Discuss treatment requirements. Some treatments require prior authorization—a confirmation from your insurer that they’ll pay for the treatment. To obtain a “prior auth”, the provider will submit a form to your insurer detailing why a treatment is medically necessary before you get that treatment. The insurer will either approve or deny the request, so you can estimate your personal cost. 
4. Choose covered medications. Most insurance plans include medication tiers, with some medications costing more out-of-pocket (usually newer, brand-name medications) and others costing less (usually older or generic medications). You may also have a different prescription copay for the different tiers. If a medication has a generic version, you can usually request that form from your provider or pharmacist.
5. Wait for the provider to file an insurance claim. They’ll submit a claim to your insurer coded to correspond with the services they provided and the total cost of the service. Then, your company will assess the amount you’re responsible for, as determined by your deductible and other agreements. This may take a few weeks.
6. Your insurer will send a claim response called an Explanation of Benefits (EOB). This document details your coverage for the visit, how much they’ll pay the provider, and the balance you owe. If something doesn’t look correct, you can call the number on the back of your insurance card to confirm the details with your insurance company. If things still look wrong, you can appeal the claim directly to your insurer. (More on EOBs below.)
7. Understand your bill. If you get a bill (or invoice) from the provider, it will detail how much they charged your insurer, the amount your insurer determined is allowed based on in-network negotiations, the amount your insurer directly paid the provider for the visit, and the balance you owe the provider. 

Why you may end up with a bill from Dr. B

When you use insurance with Dr. B, we’ll collect your copay (estimated or confirmed) as payment for your AI consultation.

After your provider has reviewed and finalized your consultation, we’ll file a claim with your insurance company for the total cost of the visit.

Some factors can influence whether you receive an invoice from us after your insurance company finalizes the claim:

• You haven’t met your deductible. Whether or not we’re in-network with your insurer, an unmet deductible means you’ll have to pay a portion (or all) of the consultation cost. You’ll likely pay more for the consultation if we’re out-of-network than if we’re in-network. After you meet your deductible, your final out-of-pocket consult cost will be lower or fully covered by your insurance plan.
• You have additional cost responsibilities. If your plan includes coinsurance or copayments, you may be responsible for these amounts in addition to your estimated copay or deductible.
• Your insurer denied the claim. Insurance companies may deny claims if the service or treatment isn’t considered essential, if a lower-cost treatment may be appropriate, or if there was a clerical error on the claim form (like an incorrect billing code). If you confirmed that your Dr. B treatment was covered before your consultation but then received a notice that your insurer denied the claim, start a chat to connect with our Insurance Specialist team. We’ll work to correct the problem. 
• You’ve reached your plan limit. Some plans cover only a set number of consultations per year. If you’ve exceeded your limit, you’ll be charged for the visit.

What if I have questions about my Dr. B bill?

For questions about your Explanation of Benefits (EOB) statement, contact your insurance company. It’s often easiest to create an online account with your insurer—many now offer chat tools and resources to help you understand common issues. Alternatively, you can call the number on your insurance card to speak with someone directly.

If you’re confused about your invoice or don’t understand an aspect of your bill, start a chat with our support team. We’ll connect you with the best Insurance Specialist to guide you through your invoice.
