If your health insurance requires a Copay then yes you'll be required to pay a copay at the time of your urgent care visit.
The amount of the copay for the urgent care visit depends on the health insurance but typically the copay is between $25.00 to $75.00 per urgent care visit.
The Copay for the urgent care visit is basically a deductible payment that you pay before your health insurance starts to pay for your urgent care visit.
Still the copay is much cheaper than paying fully out of pocket for the urgent care visit.
