For the third time since Meadowlands Hospital Medical Center in Secaucus was taken over by for-profit investors, the IRS has imposed a lien on the hospital's owners for not paying the taxes that were withheld from employee paychecks. This lien and the two previous ones have been paid off. The 230-bed hospital's financial condition has been a concern to state officials and its employees since 2011, with some lawmakers and its nurses union calling for a state monitor. But the owner — MHA LLC — has gone to extraordinary lengths to prevent public disclosure of what it considers "confidential and proprietary financial information," going so far as to demand return of written materials after meetings with state regulators to avoid leaks, according to legal correspondence with the state.
