The New York Time Company's About.com has acquired UCompareHealthCare.com (UCHC), a healthcare ratings (doctors, hospitals, nursing homes, specialty centers) , search and info site, reports paidContent.

UCHC was founded in 2004 and is based in Framingham, Mass. The purchase adds more content to About.com Health, which has some 5 million monthly unique visitors.

Site content will be free to consumers. However, the company has yet to decide how to handle the pay-for services offered to B2B clients, especially healthcare providers; all mention of them on the site has since been removed.

Terms of the deal were not disclosed, but president and founder Mark Donnelly and his staff have joined About.com, where he reports to Marjorie Martin, general manager of About.com Health.
