(Reuters) - Amedisys (NASDAQ:AMED) said on Tuesday Oregon's health authority has started a review of UnitedHealth Group (NYSE:UNH)'s $3.3 billion acquisition of the home health and hospice caregiver.
UnitedHealth had announced the acquisition in June, after competing with Option Care Health (NASDAQ:OPCH).
The acquisition was meant to help expand UnitedHealth's presence in home healthcare, a business it bolstered through a $5.4 billion deal to buy Amedisys' rival, LHC Group (NASDAQ:LHCG), last year.
Oregon's notice said it expects to complete the review within 180 days within receipt of a transaction form, which the agency had confirmed in December, according to Amedisys.
