Envision Healthcare Holdings Inc. (NYSE: EVHC) has purchased Phoenix Physicians LLC, furthering the consolidation of physician groups. 

Phoenix Physicians, headquartered in Fort Lauderdale, Florida, and Durham, North Carolina, provides services to 21 hospitals in six states. The group has more than 500 affiliated clinicians that provide emergency department, urgent care facility, adult, pediatric hospitalist, OB/GYN and high-risk perinatal services in Florida, North Carolina, New Jersey, Arkansas, Ohio and Virginia.

Envision made the acquisition through the EmCare division, which provides facility-based physician services. Envision, headquartered in Greenwood Village, Colorado, operates American Medical Response Inc. and Evolution Health LLC in addition to EmCare. American Medical provides medical transportation services, and Evolution Health provides care to patients with advanced illnesses.

Physician group M&A has continued over the past few months, with recent deals by Surgery Center Holdings Inc., which agreed to buy Symbion Holdings Corp. in June, and Apollo Medical Holdings, which agreed to pick up AKM Medical Group, also in June.
