Emergency Transport Denied by Anthem in Arizona? Appeal It the Right Way

Arizona Patients Are Being Stuck With Denied Ambulance Bills, Even in Emergencies

From Phoenix to Tucson, and across rural counties like Cochise, Navajo, and Yuma, Anthem Blue Cross Blue Shield of Arizona is denying emergency medical transportation — including 911-dispatched ambulances and medically necessary air lifts.

Commonly denied CPT/HCPCS codes:

A0427 – Advanced Life Support, Level 1
A0433 – Advanced Life Support, Level 2 (critical care)
A0425 – Ground mileage, per mile
A0431 – Fixed wing air ambulance

Frequent denial reasons:

CO-50: Service not medically necessary
PR-27: Expenses incurred after coverage terminated
CO-151: Insufficient documentation

“A patient in Flagstaff was flown to Phoenix after a cardiac event. Anthem later denied the air ambulance, claiming it wasn’t ‘pre-authorized.’ We used Counterforce Health’s tool to appeal and had it approved within a week.”
— Case Manager, Regional Medical Transport Partner

Why Anthem Denies Ambulance Coverage in Arizona and Why It’s Often Wrong

Anthem denials often cite:

Lack of prior authorization
“Alternate transport available”
“Hospital was not the nearest appropriate facility”
Insufficient documentation of medical necessity

But these reasons often violate:

The Prudent Layperson Standard, which requires coverage based on symptoms, not final diagnosis
EMTALA-related protections (when hospitals initiate transport)
Arizona Administrative Code R9-22-210, governing Medicaid ambulance claims (in crossover cases)

“They said the ER transfer wasn’t urgent — but the referring doctor documented severe stroke symptoms. Counterforce’s appeal letter quoted both state law and Anthem’s internal policy.”
— Dr. L. Sanchez, ER Physician, Yuma
