MedPost Urgent Care of San Marcos is an urgent care provider located in San Marcos, Texas at 155 Wonder World Dr. The clinic provides care of a wide range of non-emergency conditions, including flu and strep throat, sprains and broken bones, vomiting, persistent diarrhea, abdominal pain, rashes, as well as cuts, bruises and insect bites. Walk-in urgent care clinics usually have shorter wait times than emergency rooms. However, COVID, flu season and other issues have led to longer wait times in recent months. Booking online or calling ahead to schedule an appointment can cut your wait time significantly. While urgent care is covered by Medicare Part B, not all clinics accept Medicare. The same applies to Medicaid. As with all insurance, we encourage you to call the clinic or visit their website to confirm that they are in-network with your health insurance.
