BASS Advanced Urgent Care patients are typically seen within 5 minutes of arrival. Visits for patients with simple complaints can take as little as 30 minutes, those who will need diagnostic imaging or lab services may take a little longer. Most patients complete their visit within one hour or less. Since urgent care patients can walk-in to be seen at any time, occasionally patients may experience longer than the typical wait times. At BASS Advanced Urgent Care, we make every effort to staff our clinics appropriately to keep wait times short.
