Coverage under prefix IHM

HDHP

HDHP coverage under this prefix means the member carries a higher annual deductible in exchange for lower monthly premiums. Claims are processed normally but the member's cost-sharing will be higher than standard plans until the deductible is met. Preventive services are typically the exception and are covered at no cost to the member.

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.

POS

POS coverage under this prefix operates on a tiered system. Tier 1 (in-network with referral) provides the highest coverage. Tier 2 (in-network without referral) provides moderate coverage. Tier 3 (out-of-network) provides the lowest coverage. Verify which tier applies before submitting the claim.
