Coverage under prefix E4R

HMO

This prefix is linked to an HMO plan. Health Maintenance Organization coverage requires members to use in-network providers and coordinate care through a designated primary care physician. Referrals are typically required for specialist visits. Claims submitted without proper referral documentation may be denied.

Traditional Indemnity

This prefix includes traditional indemnity coverage. Indemnity plans are the oldest form of health insurance and offer maximum provider choice with no network restrictions. Members pay a percentage of charges after meeting their deductible. Reimbursement is based on reasonable and customary rates for the service area.

POS

POS (Point of Service) plans combine features of HMO and PPO coverage. Members choose a primary care physician and can get referrals to see in-network specialists at lower cost, or self-refer to out-of-network providers at higher cost. Claims should include referral information when the member uses the in-network benefit level.
