Coverage under prefix YDS

Medicare Advantage

Medicare Advantage (MA) coverage means this member receives their Medicare benefits through a private BCBS plan rather than through original Medicare. MA plans may have different payer IDs and claims addresses than the commercial plan. Check with the payer to confirm the correct submission details for Medicare Advantage claims.

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 is a Health Maintenance Organization (HMO) prefix. HMO plans have stricter routing requirements than PPO plans. Members select a PCP who manages their care and issues referrals. Claims for specialist services should include the referral number. Out-of-network claims will typically be denied unless emergency criteria are met.
