Phone and hours are printed on the currently designated Medicare Advantage predetermination form. That form retains an older identifier; its fax must not be assumed valid for services covered by newer 2026 fax-retirement notices.

Fax submissions ended April 24, 2026 for sleep studies and genetic testing, and August 23, 2026 for behavioral-health intensive outpatient/partial hospitalization and durable medical equipment requests. The older linked predetermination form still displays a fax; this record withholds it until applicability is confirmed. The notices publish telephone and electronic submission routes.

Form revision is 03/24, not October 2026; it remains designated by the current commercial forms index. Availity is also listed. Medicare/BlueCare Plus have a different form and fax. Newer 2026 notices retire fax for listed non-drug service categories; this route is restricted to the medication form purpose.
