Frequently Asked Questions

What is concierge medicine?

Concierge medicine is a relationship-centered approach to healthcare that allows more time with your provider, greater access, and greater continuity of care. At VECTOR, the goal is to build an ongoing medical relationship so your care can reflect your health history, priorities, and goals over time.

Do I need a membership to receive care at VECTOR?

No. Many VECTOR services are available without membership. Membership is required for Concierge Medicine, Hormone Optimization, and Medical Weight Management. Hormone Optimization and Medical Weight Management have memberships separate from Concierge Medicine. Their initial consultations are paid visits and do not require membership; you join if you decide to begin treatment afterward.

Does VECTOR accept health insurance?

No. VECTOR is a direct-pay practice and does not accept or bill health insurance. Patients pay VECTOR directly for services according to the applicable pricing, membership, or treatment plan.

Can I receive care if I have Medicare?

Yes. Medicare beneficiaries may receive care from John Wier, FNP-C, through a private-pay arrangement. John has opted out of Medicare. Before receiving a service that Medicare would otherwise cover, you must sign the required Medicare private contract, except where emergency or urgent-care rules apply. Neither John nor the patient submits services covered by that private contract to Medicare for payment or reimbursement. Emergency or urgent circumstances are handled according to applicable Medicare rules.

Can I receive services at VECTOR without joining concierge medicine?

Yes. Concierge membership is not required to access many VECTOR services. Medical aesthetics, regenerative medicine, hair restoration, sexual wellness, IV therapy, and other services may be available individually. Some services require an initial evaluation or have their own ongoing care options based on your individual needs.

Does VECTOR offer telehealth appointments?

Yes. Telehealth is available for appropriate visits and follow-up care when an in-person examination or procedure is not required. Whether telehealth is appropriate depends on the reason for your visit and your individual care needs.

How do I get started?

Start by scheduling a consultation and telling us what you would like to discuss. You do not need to know which service or treatment is right for you before reaching out. We can help determine the most appropriate next step based on your concerns, goals, and care needs.
