Coverage under prefix A2Z

Traditional Indemnity

Traditional indemnity coverage means the member has fee-for-service insurance with no network limitations. Any licensed provider can be seen without referrals. Claims are reimbursed based on usual, customary, and reasonable (UCR) charges. The member typically pays a deductible and a percentage of allowed charges.

EPO

This is an Exclusive Provider Organization (EPO) prefix. EPO plans do not cover out-of-network care except in genuine emergencies. Members can see any in-network specialist without a referral from their primary care physician. Claims for out-of-network non-emergency services will be denied.

Medicaid

Medicaid managed care under this BCBS prefix means the state has contracted with this plan to administer Medicaid benefits. Balance billing Medicaid members is prohibited. Timely filing requirements may follow state Medicaid rules rather than the plan's commercial deadlines. Contact the plan to confirm submission requirements.
