Coverage under prefix GRM

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.

Medicaid

Medicaid coverage under this prefix means the member's Medicaid benefits are administered by a BCBS managed care plan. Medicaid managed care claims may have different submission requirements, payer IDs, and timely filing deadlines than commercial claims. Verify the specific Medicaid plan details with the payer.

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.
