What We Do
AAS provides innovative tools for employers and payors to control claim costs and administrative expenses associated with medical services that fall outside of pre-arranged, contracted relationships such as a PPO. AAS will negotiate the best possible reimbursement rate for any medical bill making AAS your best solution to generate savings on these services where otherwise no level of discount would be realized.

DiaTri’s AAS Division provides ancillary services to the workers' compensation industry in several areas:
  • Retrospective Bill Review & Negotiations
