SAO PAULO, June 10 (Reuters) - Brazil's Diagnosticos da America (Dasa) and health insurance operator Amil are in advanced talks to combine their hospital businesses, Dasa said in a securities filing on Monday.

Under the current negotiations, Dasa and Amil would each own half of hospital chain Impar, a Dasa company that would include hospitals from Amil-owned Rede Americas, said the company.

The deal would also include the transfer of at least 3 billion reais ($559.60 million) of Dasa's debt to Impar, it added.
