Frequently asked questions

Can Parsley Health be my primary care physician?

Yes. We treat all conditions a primary care doctor would including diagnosis, testing and prescriptions. We refer out for specialty care such as OBGYN, cardiology, or surgery. Note that the costs associated with the services provided by specialists or any other healthcare provider outside of Parsley Health are not covered by your Parsley Health membership. Beyond visits, the primary mode of communication with our care team is messaging. We answer quickly during the week (within 24 - 48 hours) and always have a doctor on call to address urgent issues on weekends and holidays. We are often able to take care of acute issues without the need for a visit. A few points to remember about your Parsley Health membership: 1. We do not take insurance. However, we can provide paperwork for you to submit for out-of-network reimbursement from your insurance. You can also pay for your membership using FSA/HSA dollars. 2. We are not available for same-day emergency appointments. 3. If you have a medical emergency, we recommend that you visit urgent care or an ER.

Is testing included in my membership fee? What costs can I expect to see?

Your doctor will work with you to customize testing orders based on your health needs and personal preferences. Costs for blood work and specialty tests are not included in the membership price. Blood work is usually covered by insurance. Specialty tests range in cost from $100 - $350. These tests, however, are completely optional.

Is Parsley Health covered by insurance?

We do not accept any form of insurance. Parsley Health is classified as a primary care practice, but insurance companies don’t recognize our membership model. After each medical visit, a lab manager can provide a superbill that you can submit to insurance for out-of-network reimbursement. Many members choose to pay for their plans using FSA/HSA dollars.

Do I need health insurance if I have a Parsley Health membership?

A Parsley Health membership does not replace health insurance. We advise all members to maintain a separate health insurance plan of their choosing. For blood work, insurance frequently offers full coverage. Please also note that the Affordable Care Act (Obamacare) includes a requirement that all U.S. citizens purchase health insurance. A Parsley Health membership does not meet this requirement.

What's not included in my plan?

Cost of laboratory tests. Many tests are covered partially or fully by insurance. However, some may require a co-pay or may not be covered at all. Healthcare services in excess of those specified above, whether provided by Parsley Health or others. Non-medical services recommended by Parsley but provided by others, such as acupuncture or fitness classes. Medications (prescription and over-the-counter) and supplements.
