Side-by-Side PPO
Could your employer clients improve profits by increasing employee PPO utilization?

Would employees enjoy the opportunity to select family physicians from a second PPO network?

If so, Managed HealthCare Northwest, Inc. offers the needed flexibility! MHN will share an employer group with a competing PPO network - for new business - with no minimum enrollment requirement.

MHN will still require each employee to enroll his/her family in one PPO of choice. As before, the claims payor reports to us employees who have selected MHN PPO.

The claims payor would pay the monthly administrative fee to MHN for only those employees who have enrolled themselves and their families in our PPO - and issues MHN PPO I.D. cards (as applicable) to these employees.

If our flexibility can save money and expand access for your clients, please call us at (503) 413-5800.
