The number of healthcare options can be overwhelming, but it’s a decision that you should take your time with. Primary care is your main point of contact for your health care needs, so you want to make sure to choose someone you can trust and who can assist you with your ongoing care. Circle Medical can be the solution for you. Let’s dive into some of the reasons why.

Why People Choose Circle Medical versus Competitors Like Carbon Health?

Before breaking down the major differences between Circle Medical and Carbon Health, let’s take a look at some of the main reasons people choose Circle Medical as their healthcare provider in the first place.

A trusted primary care clinic

As mentioned, primary care is your first point of contact for any non-emergency health care needs.

Frequently Asked Questions


Why would I choose a virtual telemedicine appointment over going to my doctor’s office?

With Circle Medical, you don't have to. We have flagship clinics in San Francisco, Beverly Hills, and New York City, with more coming soon, and offer limited in-person clinic availability for our established ADHD patients at 24 shared clinic locations.

Virtual appointments allow our patients to see their providers in the comfort of their own homes, without the hassle of travel, finding parking, or taking time off of work. Our providers are also able to offer more flexible hours beyond what in-person doctor’s offices provide.

What if I need in-person testing or examinations?

For virtual appointments, if any in-person care is needed, such as bloodwork, vaccinations, or other testing, our providers are able to send the appropriate request to a nearby lab. Results will be integrated with our HIPAA-compliant mobile app so that patients have access to all of their medical records in one secure place.

How much does this cost me?

For those with insurance, cost will depend on the specific type of care you receive and the coverage of your insurance plan. We provide a cost estimate based on each patient’s insurance plan when they book an appointment.

For those without insurance, we provide the self-pay costs of each appointment when a patient is booking their appointment.

What states do you operate in?

To see our list of currently available states, begin booking an appointment.

You must be currently residing in the state of treatment as well as have your primary pharmacy be in that same state in order to be a patient at our practice.

Behavioral Health

Am I seeing a psychiatrist through Circle?

Our ADHD providers are primary care providers (MDs/DOs, NPs, and PAs) who have received specialized training for ADHD intake. They are trained by psychiatrists to ensure a high standard of care, but they are not psychiatrists themselves.

Although it is a commonly accepted practice for many primary care providers to refer their patients to psychiatrists for ADHD diagnosis and treatment, primary care providers are actually also able to diagnose and treat mild to moderate forms of ADHD themselves. If you have mild to moderate ADHD, you can benefit from having your ADHD managed by your primary care provider at Circle while getting access to all of the general practitioner services you would find at your normal doctor's office.

More complex cases will require psychiatrists to diagnose. We encourage you to please read through this entire FAQ to make sure our practice is a good fit for your needs before you book a medical appointment with a provider.


How do I know how much my specific appointment will cost?

We provide a cost estimate when you are booking your appointment. For those with insurance, your actual cost is determined after we submit the insurance claim for your appointment. Once we submit the claim, insurance companies will pay for a portion of the appointment and pass on any remaining cost to you. Once we know what this cost is, we will update you with an invoice within the app.

When do I get charged for my appointment?

For those with insurance, it typically takes 1-3 weeks for the insurance claim to be processed. Once processed, we’ll send you an invoice within the app with any remaining costs. You can then opt to pay through the app, or we will automatically charge the payment card on file after 48 hours of sending you the invoice.

For those without insurance (or with out of network insurance), we will send you the invoice 1-2 days after your appointment is completed. You can then opt to pay through the app, or we will automatically charge the payment card on file after 48 hours of sending you the invoice.


How long are the appointments?

The first intake appointment is 30 minutes. Follow-up appointments are 20 minutes each.

What insurance do you accept?

We accept over 1,500+ insurance plans. We cover most of the major PPO insurance companies (payors) across the United States. The best way to confirm coverage of your insurance plan is to begin booking an appointment on our website or via our mobile app. During the booking process, you’ll be prompted to enter your insurance information for a real-time verification of your insurance plan.

What if I am having issues verifying my insurance plan coverage?

The best way to confirm your insurance plan coverage is to call the Member Services phone number on the back of your insurance card. If needed, you can reference our Tax ID#: 474883537 and our NPI: 1134596091. Once you are able to confirm your coverage and your primary care copay costs, you can use the in-app chat to message our team with the information. We’ll then follow up with confirmation.

What is the total cost of diagnosis and treatment?

Your per-appointment costs are set by your insurance plan. If the costs seem high, you may be on a high deductible health plan (HDHP). This means that you have an annual out-of-pocket amount that you must pay on healthcare in a given year before your insurance plan will cover more of your per-appointment costs. 

If you are on an HDHP and have confirmed your insurance information in our mobile app, your remaining deductible for the year will be displayed on the “Book Appointment” page. Note that this amount may be outdated if you have had recent insurance claims processed.
