Request a weight-management visit ↓LET’S MAKE IT CLEARA few questions
A few questions
you may have.
Getting started should feel comfortable. Here’s what to know before your first visit.
Call 443-561-3657Who can request a telehealth visit?
OnPoint provides adult primary care. Patients must be physically located in Maryland during a telehealth visit. Your appointment request is reviewed to confirm that the service fits your needs.
Do I need health insurance?
No insurance is needed for the listed cash-pay visits. New-patient telehealth is $129 for 45 minutes; follow-up telehealth is $89 for 30 minutes. Ask about any outside medication or testing charges.
Can you refill my medication?
Refill evaluations are offered for non-controlled medications. You must first establish care with OnPoint, complete intake and an initial clinical assessment, and provide current laboratory information when required. Submit refill requests through your CharmHealth patient portal. A prescription is not guaranteed.
Can you review my lab results?
Yes. Your provider can review results in the context of your health history and discuss appropriate next steps. Share records through the secure patient portal, rather than Facebook or a public website form.
What if I need an in-person examination?
Some concerns cannot be evaluated fully by video. Your provider will discuss appropriate in-person care or referrals. Call to ask about limited OnPoint in-person or mobile appointment availability.
What if I have a medical emergency?
Call 911 for a medical emergency. OnPoint does not provide emergency services. Do not use appointment requests, email, Facebook, or the patient portal for emergency care, and do not wait for a reply.
Where is your office?
Our virtual office address is 10490 Little Patuxent Parkway, Suite 600, Columbia, MD 21044. This is not a walk-in clinic. Please call to confirm the location of any in-person appointment.
