Democratic Senate Leader Darrell Steinberg sent a message to the administration last week.
STEINBERG: "Do not make the actual transition unless you are assured that the child who has a doctor and sees a doctor under one program - Healthy Families - will be able to have ready access to a doctor when they're shifted."
But Rene Mollow of the Department of Health Care Services says it's carefully planned the year-long transition to minimize disruption in care.
MOLLOW: "We do have processes in place to help ensure that our plans are ready to accept these children."
Mollow says some kids will be able to keep their doctors, others won't.
