There are no real industry standards, so not all walk-in clinics are the same in terms of services or pricing. Even though the clinics will charge different prices, depending on location, the base prices range between $75 and $125. That is for the normal services and not specialized ones. You should expect to incur additional costs if you require a special service or medication such as a lab test, an X-ray, or an immunization shot. These may range between $50 and $150, again depending on location. Of course, these costs apply only when you are paying in cash as opposed to using your insurance policy. If you are walking in with insurance, on the other hand, you can expect to co-pay around $20-$50, depending on location, your plan and whether you are in network with the provider.
