LHC Group Inc., a Lafayette-based home nursing firm, has completed a previously announced $10 billion deal for 13 home health agencies in six states.

The Life Care Home Health agencies increase LHC’s geographical footprint to 350 locations in 29 states.

LHC announced the deal in July. The agencies are expected to have no impact on 2014 earnings but will increase the 2015 results.

The Life Care Home Health agencies cover 44 counties in Arizona, Colorado, Massachusetts, Tennessee, Utah and Washington. Those counties have an estimated 2 million people aged 65 and older. The agencies generated $28 million in revenue for the 12 months ending in June.

LHC is also acquiring a Life Care agency in Rhode Island, but a different regulatory process and timeline means the deal won’t close until later this year.
