An urgent care provider in Houston, Texas, Memorial Hermann Urgent Care Washington Avenue is located at 4500 Washington Ave. The clinic treats non-life threatening injuries and illnesses, as well as routine immunizations and wellness visits. Most urgent care clinics are equipped to take x-rays and run EKG tests, urinalysis, blood tests, STD tests, pregnancy tests, drug tests, as well as flu and step tests. 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.
