Effective July 1, 2019, the County of Los Angeles is no longer utilizing third-party claims administrator (TPA) TriStar Risk Management.
Claims are transferred to either York Risk Services or Sedgwick Claims Management, depending on the specific claim number. The change affects all dates of service. Claim numbers do not change, and bill review services remain the same for all claim numbers. Providers should submit all second review appeals to the appropriate new TPA, even when the original bill was submitted to TriStar.
Read on for details.
Refer to the table below to determine which TPA now administers LA County claims that were formerly administered by TriStar. The table also lists the mailing address, clearinghouse, and electronic billing Payer ID for LA County which applies for each clearinghouse, as well as the (unchanged) bill review service:
