Primary care at home in St. Charles County
St. Charles County sits west of the Missouri River and north of St. Louis County, and it includes both older river towns and fast-growing communities along the Interstate 70 corridor. Many residents have specialists and hospitals on the other side of the river, which can turn a single appointment into a long trip.
Primary care at home brings the clinician to you. Gateway’s clinicians provide the medical care. We connect adults with partner clinicians and manage the practical steps around the visit. Start with our overview of primary care if you want to see the full range of care that can be arranged.
Who visits
Visiting clinicians who see patients through Gateway may be physicians, podiatrists (DPM), nurse practitioners or nurses, matched to the patient’s needs. The treating clinician makes every clinical decision.

What a house call can include
The treating clinician decides what each visit covers. It can include a health history, an exam, a medication review, follow-up on long-term conditions such as diabetes or heart disease, orders for tests or equipment, specialist referrals and a conversation about future care wishes. The page on house calls for seniors describes what older adults often ask about.
When a test or treatment needs a hospital or specialty office, the clinician will say so, and Gateway can help with scheduling and transportation arrangements.
Why distance matters here
In a county where homes can be spread out, small barriers add up. Rides depend on family schedules, bad weather makes roads harder, and a walker or wheelchair makes a car trip tiring. People then delay care until a problem is larger.
A home visit gives a clinician a look at the living space too, which can raise practical questions about stairs, lighting, medications on the counter and who helps each day. Those details rarely come up in a short office visit.
Working with your current doctors
Many residents see physicians in St. Louis County or at hospitals across the river. A house call does not have to replace them. With your permission, visit notes go to your current doctors, and the clinicians can agree on who handles refills, forms and test results. If you have no primary care clinician, tell us when you call.
Where visits take place
- Private houses and apartments
- Assisted living and memory care communities
- Skilled nursing facilities and rehabilitation centers
Visits in a community are arranged with the community and the resident.
Coverage and cost questions
You can ask about Medicare, Medicare Advantage, Medicaid and commercial plans. What you might owe depends on the treating provider, your plan and the care needed. Our page on Medicare and primary care at home lists questions to ask your plan before a first visit.
How to start
Call 314-325-0126 with the patient’s ZIP code, or send a request for care with a name and phone number. Please keep medical details for the phone call. We confirm availability for the address and explain the next step. Family members can call for someone else, and no referral is needed to start.
For an emergency such as chest pain, trouble breathing, signs of a stroke or heavy bleeding, call 911. House calls are planned care.
Common questions
Is every part of St. Charles County served?
Gateway coordinates care across Greater St. Louis, but availability is confirmed by address and care setting. Call 314-325-0126 with the ZIP code, and we will explain what we can arrange for that location.
I live in O’Fallon. Which page applies to me?
It depends on the state. O’Fallon, Missouri is in St. Charles County. O’Fallon, Illinois is in St. Clair County, in the Metro East. Give us your full address and we will point you to the right information.
Can a house call replace my regular doctor?
Only if you choose that. Some people keep a trusted physician and add house calls; others have no clinician who can see them at home. We help the clinicians stay in contact either way, with your permission.
Do you work with senior living communities in the county?
Yes, you can ask. Visits in assisted living, memory care and other communities are arranged with the community as well as the resident, and the treating clinician works alongside the nursing staff.
Can my adult child arrange the visit from out of town?
Yes. A family member or caregiver can make the first call, even from another city or state. You decide who attends visits and who receives updates, and we keep the people you name informed. Have the patient’s address, insurance details and current doctors’ names ready when you call.
