Fulton County Superior Court Judge Marvin S. Arrington Sr. has ordered an insurer to continue paying the major share of treatment for a Woodstock, Ga., man suffering from terminal cancer whose benefits were slashed when he failed to enroll in Medicare.

Steven A. Detch says he was repeatedly told by a representative of Blue Cross and Blue Shield of Georgia that his private coverage would be unaffected even if he declined to enroll in the government program. But several months later, according to a complaint filed in Fulton County Superior Court, the company cut its payments from 80 percent to 20 percent of the roughly $100,000-a-month chemotherapy sessions.
