Payer ID

Every electronic transaction has to name its receiver, and in practice that name is the payer ID, a short code the clearinghouse network reads to route the file. HHS described payer IDs in 2019 as industry-derived identifiers that are not based on HIPAA, and acknowledged that the industry already routes HIPAA transactions with them; commenters named claims, eligibility, claim status and enrollment among those transactions¹. Payers publish the IDs they accept. Wellcare’s Medicare claims page for Arkansas providers, for example, names payer ID 14163 for fee-for-service claims and Availity as its preferred EDI gateway, while letting providers use their own clearinghouse³.

There was once a plan for a national identifier. HHS adopted the health plan identifier, or HPID, in a 2012 final rule, announced in 2014 that it would not enforce it, and then rescinded it after hearing about the burden and cost from stakeholders and its advisory committee². The industry’s case was that payer IDs already did the routing job, and the rescission took effect on December 27, 2019¹. No federal identifier replaced it, so the working reference is the payer’s own published ID and the payer list your clearinghouse keeps.

Payer ID mistakes produce rejections, not denials. They come from sending a Medicare Advantage or Medicaid member’s claim under the same company’s commercial ID, keeping an old ID after a plan changes claims administrators, or mixing up the payer ID with the member ID or group number on the card. Store the payer ID on the plan record in the practice system, and check it first when a claim comes back saying the payer or member could not be found.
