Veteran firefighter Ken Jones has discontinued his insurance coverage with Blue Shield as part of a plan to receive the immunotherapy his former insurer previously denied under Jones’ Medicare Advantage plan. Jones, 71, has decided to enroll in basic Medicare in hopes the federally administered insurance program will cover the cost of his immunotherapy.  His oncologist is hopeful the change will result in Jones receiving his next round of treatment later this month. Jones was diagnosed with Stage 4 lung cancer last year, which his doctor believes is linked to his 17 years working amid smoke and ash as a San Francisco firefighter.
