New members to be issued alphanumeric subscriber IDs starting Feb. 27
We’ll issue alphanumeric subscriber IDs to all new Blue Cross Blue Shield of Michigan and Blue Care Network members, starting Feb. 27, 2021. The start date was communicated in a web‑DENIS message posted Feb. 24.
We announced in the June Record that we’d be transitioning to alphanumeric IDs this year, but the start date wasn’t available at that time.
We’ll use the letter M after the prefix to begin the alphanumeric ID, followed by eight numbers. For example, a new subscriber ID could look like this: XYZM91234567. When you see one of these ID cards and check benefits and eligibility on web‑DENIS, you’ll enter the last nine characters of the subscriber ID.
These de‑identified IDs are being used to avoid duplication with subscribers’ Social Security numbers, align with other health plans and automate manual processes previously used when correcting duplicate numbers.
There are currently no plans to change subscriber IDs for existing members. |
