Prior Authorization – Lab and Pathology Services

HealthCare Partners has a preferred in-network laboratory contract with Quest Diagnostics and their affiliate, Ameripath, for outpatient lab testing. It’s important to refer your patients to an in-network laboratory. 

Maximum coverage & minimum cost:

Out-of-network lab services are not covered under our members’ benefit plans. When referred to Quest Diagnostics, a member receives the maximum plan benefit and a lower out-of-pocket expense.

Data for our condition management programs

Data from out-of-network testing is not available for our disease management programs. This may result in inaccurate reporting and the possibility of practitioners and/or members being told that a member needs testing when it may have already been completed.

To establish an account, call (866) 697-8378 (select option 1, then option 8).

Register for Care360, to order lab tests and get results from Quest Diagnostics at no cost to you.

Quest Diagnostics has a full list of standard and specialty lab tests. Use the Quest Diagnostics Test Directory to search the full test menu.

Remind your patients that they can find one of the 2,200 Patient Service Centers by calling (866) MYQUEST or (866) 697-8378.

Genetic Testing

All genetic testing services can be obtained through Quest Diagnostics Lab, and require Prior Authorization prior to submission of any specimens for testing. Quest arranges for the transfer of specimens to appropriate reference labs if specifically approved tests cannot be performed directly by Quest.

A request for Prior Authorization can be submitted to HCP in one of two ways:

  1. The preferred and most efficient way to submit a Prior Authorization (PA) request is via the HCP Web-based data interface, EZ-Net.

    Login credentials for EZ-Net are required. Learn More about EZ-Net.

  2. Prior Authorization requests may also be submitted via FAX.

Send a completed Authorization Request form to (888) 746-6433 or (516) 746-6433.
