Families don’t all have to be with the same carrier either. Some parents have chosen a PPO plan for their children because certain doctors who are treating their children are in-network with the PPO plan. The parents then choose a less expensive HMO plan for themselves. It could be that a family member needs surgery during the next year. That person might opt for a Gold or Platinum plan to reduce out-of-pocket expenses while the other family members hang out in the Bronze or Silver metal tier level.
