Blue Cross and Blue Shield of Illinois
Illinois • High-Deductible Health Plan (HDHP), Medicare Advantage, POS
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.
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 coverage under this prefix operates on a tiered system. Tier 1 (in-network with referral) provides the highest coverage. Tier 2 (in-network without referral) provides moderate coverage. Tier 3 (out-of-network) provides the lowest coverage. Verify which tier applies before submitting the claim.
