PHILADELPHIA - A Pennsylvania federal judge on March 27 dismissed a suit challenging the coverage and reimbursement of chiropractor claims, saying that one plaintiff failed to exhaust administrative remedies and that two other plaintiffs lacked standing (American Chiropractic Association, et al. v. American Specialty Health Inc., et al., No. 12-7243, E.D. Pa.; 2014 U.S. Dist. LEXIS 41769).
