How to Schedule and Prepare for a MedStar Appointment
How to reach MedStar to book or reschedule an appointment
MedStar Health operates multiple hospitals and outpatient clinics across the Mid-Atlantic region, primarily in Maryland and Washington, D.C. To schedule an appointment, you'll call the specific facility or department where you need care — MedStar doesn't have a single central booking line. The number you need depends on which hospital or clinic location you're trying to reach and what type of care you're seeking.
Start by identifying which MedStar facility is closest to you or where your doctor practices. MedStar's website lists all locations with their direct phone numbers. When you call, have your insurance card and photo ID ready. If you're a new patient, the scheduler will ask for your date of birth, address, and the reason for your visit. If you're an existing patient, they'll pull up your chart using your name and date of birth.
Most MedStar locations also allow online scheduling through their patient portal if you've already been seen there. You can log in, view available appointment times, and book directly without calling. This option is fastest if you're a returning patient and your appointment type supports online booking.
Key Takeaways
- Call the specific MedStar location or department where you need care — there is no single central appointment line for the entire system.
- Have your insurance card, photo ID, and the reason for your visit ready when you call.
- Returning patients can often book appointments online through the MedStar patient portal without calling.
- Appointment wait times vary by location and specialty, but most routine appointments can be scheduled within two to four weeks.
- If you need to cancel or reschedule, call the same number where you booked at least 24 hours before your appointment.
What information you'll need to provide
When you call to schedule, the scheduler will ask for several pieces of information. Have your insurance card handy — they'll need your member ID, group number, and the name of your insurance company. If you don't have insurance, tell them that upfront; MedStar has financial counselors who can discuss payment options and programs that may help with costs.
You'll also need to provide your date of birth, current address, and phone number. If this is your first visit to that location, they'll ask why you're coming in and whether you have a referral from another doctor. If you do have a referral, have that information ready — some insurance plans require a referral before you can see a specialist, and MedStar will verify it before confirming your appointment.
If you're seeing a specific doctor, have their name ready. If you don't have a doctor in mind but need a particular type of care — say, cardiology or orthopedics — the scheduler can suggest available providers at that location.
Appointment types and what to expect at each
MedStar offers several types of appointments depending on your needs. In-person appointments at a hospital or clinic are the standard — you'll check in at the front desk, wait to be called back, and see a provider in an exam room. Bring your insurance card and photo ID, and plan to arrive 10 to 15 minutes early to allow time for check-in.
Telehealth appointments are available for many types of visits, especially follow-ups and routine consultations. You'll receive a link via email or text message before your appointment. Test your internet connection and camera beforehand, and find a quiet, private space where you can talk without interruption. You'll still need your insurance information, and the provider may ask you to describe symptoms or perform simple checks (like checking your blood pressure at home if you have a monitor).
Urgent care visits at MedStar's urgent care centers don't require an appointment — you walk in and check in at the desk. These are for injuries, infections, and other issues that need attention but aren't emergencies. Wait times vary; calling ahead can sometimes give you an idea of how busy the center is.
Emergency department visits are for life-threatening situations. Call 911 or have someone drive you to the nearest MedStar hospital's emergency department. You don't schedule these — you arrive and are triaged immediately based on the severity of your condition.
How long appointments typically take
The time from when you arrive to when you leave varies widely depending on the type of appointment and how busy the location is. For a routine office visit with a doctor or nurse practitioner, plan for 45 minutes to an hour total — this includes check-in, waiting, and the actual visit. Some visits are shorter, especially if it's a follow-up for a known condition.
Specialist appointments often take longer, sometimes 60 to 90 minutes, because the provider may need to review imaging, run tests, or spend more time on a complex issue. Procedures like blood draws, EKGs, or ultrasounds add time on top of the visit itself.
Telehealth appointments are usually shorter — typically 20 to 30 minutes — because there's no check-in process and the visit is more focused. However, if the provider needs to examine you or discuss something complex, it may run longer.
What to bring and how to prepare
Bring your insurance card and a photo ID to every appointment. If you have any medical records from other providers — test results, imaging, previous diagnoses — bring those too, or ask your previous provider to send them to MedStar before your visit. This helps the new provider understand your full medical history.
Wear comfortable, loose-fitting clothing that allows easy access to your arms (for blood pressure checks) and legs (if an exam is needed). If you're having a procedure, follow any fasting or preparation instructions the scheduler gave you when you booked — these are important and affect whether the appointment can go forward.
Bring a list of all medications you're currently taking, including over-the-counter drugs and supplements. If you can't remember the exact names or doses, bring the bottles themselves. Also write down any questions or concerns you want to discuss so you don't forget during the visit.
If you're a new patient, arrive 10 to 15 minutes early to complete paperwork. Returning patients should arrive 5 to 10 minutes early. If you're running late, call the location immediately — they may be able to work you in, or you may need to reschedule.
Canceling or rescheduling your appointment
If you need to cancel or reschedule, call the same number where you booked your appointment. Try to give at least 24 hours' notice so the time slot can be offered to another patient. If you cancel with less notice or don't show up without calling, some MedStar locations may charge a cancellation fee or require you to reschedule through a different process.
If you're rescheduling because of a scheduling conflict, the scheduler can often find you another time right away. If you're canceling because you're sick or have a new symptom, let them know — they may recommend urgent care or a telehealth visit instead of waiting for your original appointment date.
If you miss an appointment without calling, MedStar may reach out to you to reschedule. Repeated no-shows can result in your being discharged from a provider's care, so it's important to either keep your appointment or cancel ahead of time.
If you have trouble reaching your location or need help
If you call a MedStar location and can't reach anyone, try calling during business hours — many clinics have limited phone staffing early in the morning or late in the day. You can also visit the MedStar website and use their online scheduling tool if you're a returning patient, or look for a "contact us" form to send a message requesting a callback.
If you're having trouble understanding your appointment instructions or have questions about what to bring, don't hesitate to call back and ask. The scheduler or nurse line can clarify anything that's unclear. If you have financial concerns about the cost of your visit, ask to speak with a financial counselor — they can discuss payment plans or programs that may reduce your out-of-pocket cost.
If you're a new patient to MedStar and don't have a primary care doctor, you can ask the scheduler to recommend one at the location you're calling. Many MedStar providers accept new patients, and the scheduler can tell you who's available.
Frequently Asked Questions
Can I book a MedStar appointment online without calling?
If you're a returning patient and have already been seen at that MedStar location, you can log into the patient portal and book many types of appointments online. New patients typically need to call to schedule their first visit so the scheduler can collect your full medical history and insurance information.
What if I don't have insurance?
Tell the scheduler when you call. MedStar has financial counselors who can discuss payment options, sliding scale fees based on income, and programs that may help cover costs. You can still schedule your appointment — insurance is not required to receive care.
How far in advance do I need to book a routine appointment?
Most routine appointments can be scheduled within two to four weeks, depending on the provider and location. Some providers have openings sooner, and urgent issues may be fit in faster. If you need to be seen quickly, mention that when you call and ask if there are any sooner times available.
What happens if I'm late to my appointment?
Call the location as soon as you realize you'll be late. Many providers will still see you if you arrive within 15 to 30 minutes of your scheduled time, but some may ask you to reschedule if you're significantly delayed. It depends on the provider's schedule and how busy the clinic is that day.
Do I need a referral to see a specialist at MedStar?
It depends on your insurance plan. Some plans require a referral from your primary care doctor before you can see a specialist; others don't. When you call to schedule, tell the scheduler your insurance company and they'll let you know if a referral is needed. If it is, they can often help coordinate getting one from your doctor before your appointment.
