Payer directory
Where this listing comes from
Medicare Advantage and Part D contracts from CMS, Medicaid managed care plans from Medicaid.gov, insurers from their loss ratio filings, the carriers employer plans name on their Form 5500 filings, and the Medicare contractors and the plans whose own provider pages Payerworks read.
Rows from two files are joined only by a number both carry (a NAIC code, then a tax ID). Inside one file, the file’s own grouping stands: a CMS legal entity’s contracts are listed under it, and a Medicaid plan’s state programs under the plan’s name. Two rows whose names merely agree are kept apart for a person to decide.
Most rows have no payer ID: a payer ID is a routing code each clearinghouse assigns, and Payerworks lists only the ones payers state.
