Blue Cross and Blue Shield of Illinois
Illinois • Medicare Advantage, POS, High-Deductible Health Plan (HDHP)
This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.
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.
This is a High-Deductible Health Plan (HDHP) prefix. These plans have minimum deductible thresholds set by the IRS. Members often use HSA funds to cover out-of-pocket costs. The plan's claims processing and payer ID are the same as the standard plan, but expect higher patient responsibility amounts on remittance.
