Change in Texas Pharmacy Prior Authorization Call Center Fax Number

Last updated on

There is an update to this article: click here.

The Texas Pharmacy Prior Authorization (PA) Call Center fax number (866-617-8864) is currently experiencing technical issues. It cannot receive or send faxes related to Medicaid fee-for-service pharmacy prior authorization requests.

A new toll-free fax number is now available. Providers should fax prior authorization requests to 844-419-6543 until further notice.

The Texas Prior Authorization Call Center still takes prior authorization requests by phone or online. Call 877-PA-TEXAS (877-728-3927), or register and refer to the “PA Request” option at PAXpress (paxpress.txpa.hidinc.com).
