Blue Cross Prefix List (Updated Often)

Thank you to all of you who are commenting with more prefixes! It’s great to see this list growing. I appreciate all the feedback and some of the tips that come with them.

Because the comments are getting so numerous, I’m going to start deleting the ones that get integrated into the list. I’ll add the screen name of the person who supplied the prefix, unless someone requests otherwise.

Please let others know of this information so they can find what they need. Leave comments with anything else you’d like to know.

Below are not the only known BC/BS/Anthem prefixes, but the only ones we’ve verified by calling their 800 number.

(If you can’t find what you’re looking for, try the non-verified list of prefixes.)

    Awesome resource, thanks for compiling it. I do DME billing and collection.

    Channin: when there is “AN” following the 3 letter prefix, that is Anthem.

    Also, here are some I have uncovered that are not on the list above. These are all confirmed either via phone calls or an EOB:

    AUY, AZQ = Anthem of WI Medicare Supplement
    AZF = BCBS of Mississippi

    ETH = BCBS of Illinois
    EXA = Ohio (Extendicare Health Services)
    FDU = Anthem (UBEW)
    FIA = Anthem of WI
    FQF = BCBS of MN (Fleet Wholesale Supply)

    GH_ = Delphi group of BCBS of MI (Northwood NPN)
    GM_ = General Motors group of BCBS of MI (Northwood NPN)
    GPP = BCBS of MN (Gold ‘N Plump)
    GYA is up there–this is the Goodyear group of Anthem of Ohio
    The list has HHM as South Carolina, but I have found it to be Rhode Island (?)
    HJK = BCBS of Texas
    HPU = BCBS of IL
    HQM = Mountain State (WV) Medicare Advantage plan
    IAZ = Wellmark of Iowa Medicare Blue PPO

    NEI = National Elevator Industry (Illinois)
    NSC = Anthem of Virginia
    NSU = National account, “Nisource,” dedicated phone #800-228-2891
    NWE = Minnesota
    OHP = Ohio University (Anthem)
    ONX = South Carolina
    OTP = Minnesota (Otter Tail Corp
    PEM = Minnesota (Pemstar, Inc. employees)
    PLN = Anthem (PolyOne nat’l acct)
    PLZ = BCBS of Arkansas

    TFM = Minnesota (Duluth Building Trades)
    TYM = Wellmark of Iowa (Tyson Foods)
    UCR = Anthem, Charter Communications
    UWE = BCBS of Ohio, but need to call the out of state ph #
    The list has WMD as Nebraska, but I know for sure this is Wilson-McShane (claims admins, not a group) in Minnesota.
    XNA = Regence BCBS of Idaho
    XZ_ = Minnesota, XZG and XZS are PMAPs (or MSHOs, a Minnesota thing: Medicare Advantage/Medicaid combo HMO)
    YRT = Anthem of Indiana
    YYN = Pennsylvania (Highmark)
    ZPM = Mountains State of WV Freedom Blue

    As huge as your list is, I’m amazed I could add so many more. I think BCBS uses every possible 3 letter combination in the alphabet.

  30. Jason says:

    BNF=BCBS OF IL

  31. Janet says:

    We’ve compiled a list where I work and I out on the web. The address is

  34. Andrea Hersey says:

    Sammie,

    I just saw your post. When you call the number for UHC, ask to speak with a representative in the United States. They MUST transfer you to the US without question. I do this for all my calls as 1/2 the time I can’t understand the person answering the phones. This works across the board for all out-sourced phone calls.

    Hope this helps!!
