Coverage under prefix GTT

HMO

HMO coverage means this member must use providers within the plan's network. A primary care physician serves as the care coordinator and must authorize specialist referrals. Emergency services are the primary exception to the network requirement. Always verify referral status before providing non-emergency specialty care.

POS

This prefix is linked to a POS plan. Point of Service coverage gives members a choice at the time of service: use the HMO-style in-network benefit with a referral for lower costs, or access out-of-network providers at reduced coverage levels. The billing approach depends on which option the member chooses.

Medicare Advantage

This prefix is associated with Medicare Advantage. MA plans combine hospital (Part A) and medical (Part B) coverage, and many include prescription drug coverage (Part D). When billing, confirm whether the plan uses the same payer ID for MA claims as for commercial claims, as many BCBS companies use separate IDs.
