NEW YORK —  CVS Health is looking at the acquisition of primary care center operator Oak Street Health, Bloomberg News reported on Monday citing people familiar with the topic.

No final decision has been made and discussions could fall through, the report added.

CVS declined to comment while Oak Street did not immediately respond to a Reuters request.

Oak Street Health runs primary care centers across United States for recipients of Medicare, the U.S. government insurance program for Americans aged 65 and older, and has private equity firms such as General Atlantic and Newlight Partners among its shareholders.

CVS has been expanding its products beyond managing health and pharmacy benefits with acquisitions in recent years, including its $8 billion buyout of home healthcare service company Signify Health last year.
