PORTLAND, Maine (AP) – Coordinated Transportation Solutions of Connecticut has failed to obtain a performance bond as required by its contract with the state of Maine. The company is under fire for its poor performance as a provider of non-emergency transportation for people in Maine’s Medicaid program. MaineCare patients have lodged thousands of complaints against Coordinated Transportation Solutions of Connecticut, mostly from people who say they have missed medical appointments or been left stranded. The Maine Department of Health and Human Services has threatened to cancel the company’s $28.3 million contract. State officials said the company’s performance bond could be revoked. A performance bond would help cover the state’s cost to transition to a new broker if it canceled Coordinated Transportation Solutions’ contract, but an agency spokesman says there is no performance bond.
