In general, chiropractic services range from approximately $30 to $200 per session. Of course, each type of treatment has a different cost. For example, an initial consultation with a chiropractor may be provided at no charge, while a typical therapy session costs about $65 on average.
In rural areas and in the Midwest region, chiropractic treatments may be less expensive, while in big cities and in Southern areas, you can expect to pay more for chiropractor services. On the low end, chiropractic sessions start in the $50 range, while on the higher end, you can expect to spend $100 or more.
