IF YOU LIKE YOUR DOCTOR, YOU CAN KEEP YOUR DOCTOR. PERIOD. UnitedHealthcare to cut doctors for Mass. seniors. “National insurance giant UnitedHealthcare plans to cut up to 700 Massachusetts doctors from its physician network for seniors enrolled in its private Medicare plan as a way to control costs, according to company officials. For elderly patients enrolled in the plan, the cuts mean they will have to find a new doctor or eventually switch to a new health plan that covers their current doctor.”
