Where payer ID IL621 goes on a claim

On an electronic professional (837P) or institutional (837I) claim, the payer is identified in loop 2010BB, the payer name loop. The NM1 segment there carries entity identifier code PR (payer), the payer's name, the qualifier PI in NM108, and the payer ID itself in NM109:

NM1*PR*2*MEDICAID ILLINOIS*****PI*IL621~

The same NM1*PR structure names the payer in loop 2100A of 270 eligibility and 276 claim status requests. Many clearinghouses use one payer ID for claims, eligibility, and claim status, but some assign a separate ID per transaction, so check the payer list for each transaction type you send.

Before you submit to payer ID IL621

  1. Read the member's ID card

    The claims payer ID or claims address printed on the card is the most specific source for that member's plan. Where it differs from a directory listing, the card generally reflects how that plan wants claims sent.

  2. Check whether a third-party administrator runs the plan

    Self-funded employer plans route claims to their administrator's payer ID, which is often different from the network or carrier name printed on the card.

  3. Confirm the ID on your clearinghouse's payer list

    Payer IDs are assigned per clearinghouse. Large national payers tend to use the same ID nearly everywhere; regional plans and administrators often do not. Search your clearinghouse's list for IL621 and confirm it maps to Medicaid Illinois.

  4. Watch the acknowledgments, not just the remittance

    A wrong payer ID fails at the clearinghouse or on the 277CA claim acknowledgment, not as a denial on the 835. A rejected claim was never received by the payer, so the timely filing clock keeps running until a corrected claim is accepted.
