The U.S. Government Accountability Office has completed its review of the long term care insurance industry’s claims-handling practices.

For the time being, however, the GAO is not releasing its report on its findings, at the request of Sen. Charles Grassley, R-Iowa, who had requested the study.

Grassley, the senior Republican on the Senate Finance Committee, asked the GAO to investigate in September after a New York Times report charged that some LTC carriers may have rejected or delayed legitimate claims unfairly.

Grassley also asked the office to evaluate whether state insurance regulators are adequately dealing with complaints about unjustified LTC benefit denials.

The GAO sent its report to Grassley on June 30. He then asked the agency to embargo the report’s contents for 30 days, a GAO spokeswoman says.
