Availability and how to access care after hours

All KC locations have regular office hours for routine appointments, and every clinician has same day appointment slots for urgent needs. If you cannot get into your Kansas City primary care physician because they are already full or out of the office, you may see any other available clinician. Three of our four locations have urgent care located on site, and these are walk-in visits, no appointment needed.

For specific location’s regular and urgent care hours see each location’s page by clicking on the links to the left. By staying in our practice for your urgent care needs, you ensure your records will be available to the urgent care provider as well as to your primary care provider if you need follow-up care. All offices are linked and use the same health record. If you need medical advice after hours, you may either call the community nurse advice line or call the main office line for your primary care provider’s KC metro office, and the answering service will connect you to a physician on-call. A physician is always available for this emergency phone advice when the office is closed. If the advice needed is non-urgent, you may also log in to the portal and send us a message electronically at any time, 24/7.
