Exact Science's Cologuard; Payers; Lawsuits; Colon Screening Policies

Exact Sciences markets the FDA-approved colon cancer screening test based on stool DNA analysis.  It is endorsed by the American Cancer Society (ACS) guidelines and by a Medicare NCD.  However, for many health plans, it is not a required benefit, as it is not endorsed by the US Public Services Task Force.  Based on several recent news stories, the manufacturer sues Humana, on the basis that Kentucky law (and some other states) use ACS guidelines as a state-based standard of coverage.
