1 Sessions can range from $34 to $106 per session depending on where you live, how many regions of the spine a chiropractor services and whether exams are required. 2  Average fees are highest in the South, around $70 per session, and lowest in the Midwest, at $60. am sorry to inform you that $100 per visit on a lien basis is cheap and that $100 can usually be negotiated at settlement time. In my state chiropractors charge about $190 a visit for P.I cases, but when settlement time comes they may average like $100 a visit-it just depends on the amount of the settlement.
