Amazon.com Inc. is in internal discussions to open primary care clinics in its Seattle headquarters, CNBC reported Aug. 9, citing anonymous sources.

The preliminary plan is to hire a small number of doctors to start a pilot clinic later this year for a select group of workers and then expand it to more employees in early 2019, according to CNBC.

In July, CNBC reported that the online retail giant was in discussions with startup Xealth for a pilot project that would deliver doctor-recommended medicines to patients after they are discharged. The pilot is reportedly set to begin in a matter of months.

Amazon in June agreed to acquire online pharmacy PillPack. The company is also working with Berkshire Hathaway Inc. and JPMorgan Chase & Co. to launch a technology-focused healthcare company that will be led by Atul Gawande, an American surgeon, writer and public health researcher.

Amazon declined a request for comment from S&P Global Market Intelligence.
