WEST PALM BEACH, Fla. - A Florida federal judge on March 6 denied a motion to dismiss claims asserted against ambulatory surgical centers and billing companies for allegedly fraudulently billing for chiropractic services, saying that the Employee Retirement Income Security Act did not preempt the claims (United Healthcare Services Inc., et al. v. Sanctuary Surgical Inc., et al., No. 10-81589, S.D. Fla.; 2014 U.S. Dist. LEXIS 28824).
