Coverage under prefix XTT

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.

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.

POS

This is a Point of Service (POS) prefix. POS plans offer flexibility similar to a PPO but incentivize in-network care through lower cost-sharing. Members designate a primary care physician who can issue referrals for the highest level of benefits. Out-of-network claims are covered but at significantly reduced rates.
