PROVIDENCE, R.I. (AP) _ A Massachusetts hospital chain has filed an anti-trust lawsuit alleging that insurer Blue Cross & Blue Shield of Rhode Island improperly blocked its bid to acquire the Landmark Medical Center in Woonsocket.
Steward Health Care System filed its suit Wednesday in state Superior Court.  It says Blue Cross & Blue Shield interfered with the sale in an attempt to maintain its position as the main buyer of hospital services.
The sale fell through after Steward and Blue Cross failed to reach an agreement on how much Blue Cross would pay for services at the hospital.
Representatives of Blue Cross & Blue Shield say the insurer will defend itself in court and is confident it will prevail.
Landmark has since entered a deal to be purchased by a California-based hospital chain.
