The Centers for Medicare & Medicaid Services has taken a step toward answering that question in a new, 12-page guidance document that seeks to define whether a facility qualifies as a hospital under section 1861(e) of the Social Security Act.

At the heart of the question is that law’s definition of a hospital, which includes that it is “primarily engaged” in caring for inpatients.  CMS’s guidance outlines parameters for determining whether a hospital meets this standard.
