Astrana's current Prospect support page: written provider disputes within 365 days of the payment/denial, using the PDR form plus supporting documents, fax Attn: PDR. The mailing address is withheld because sources conflict: the Astrana support page gives P.O. Box 11466, Santa Ana, CA 92711 (Attn: PDR), while Prospect's PDR form (rev. 01/19/23) says 600 City Parkway West, Suite 1000, Orange, CA 92868. Confirm before mailing.
