The Rhode Island House Oversight Committee is scheduling another hearing concerning Medical Transportation Management. The Missouri-based company began providing services for Medicaid patients for non-emergencies this year, but has been plagued with complaints of delayed service or worse. Most recently, the state Division of Public Utilities and Carriers has been investigating allegations that MTM conspired with taxi drivers to operate outside of authorized territories and charge illegal rates. The committee is meeting tomorrow at 5 p.m.
