Ambulatory Services of America Inc. has acquired majority interests in six dialysis joint ventures, all in the San Fernando Valley area of Los Angeles.

Financial terms of the deal, announced today, were not disclosed.

The seller, Southern California-based Kidney Centers Inc., provides care to 700 patients through the six dialysis centers. The acquisition, which ASA is making through its Innovative Dialysis Systems subsidiary, also includes KCI’s acute dialysis program, a series of service agreements between KCI and a group of eight hospitals.

With the acquisition, Brentwood-based ASA now owns 85 dialysis facilities.

“Given the strong presence of Innovative Dialysis in the Los Angeles area, we had long known of KCI, and we appreciated its physician joint venture model, which is much like ours,” Timothy Martin, chief executive officer of ASA and Innovative Dialysis, said in a release. 

The acquisition included all of the acute centers KCI owned but not two de novo operations, according to Douglas Chappell, Ambulatory’s executive vice president.

The six facilities are Kidney Dialysis Center of Northridge, Kidney Center of Panorama City, Kidney Center of Sherman Oaks, Kidney Center of Van Nuys, Kidney Dialysis Center of Verdugo Hills and Kidney Dialysis Center of West Los Angeles.
