The U.S. Justice Department on Monday filed a lawsuit against the state of Florida, accusing officials of unnecessarily keeping children with disabilities in nursing homes.

The lawsuit claims federal officials visited six nursing homes around the state and identified about 200 children who didn't need to be there and could receive care at home.

Federal officials concluded that the state has made it difficult for disabled children to get medical services that would allow them to move home. The lawsuit said Florida's system has led to unnecessary segregation and isolation of children, often for years.

The federal government had threatened a lawsuit last September, if the state failed to make changes to the system.

State health officials did not immediately respond to a request for comment.
