Most benefit Plans administered by Mutual Medical utilize Preferred Provider Organizations or PPOs.  Services rendered by PPO providers are typically billed at a lower rate due to negotiated discounts and paid at a higher benefit level.  

Refer to your ID card to determine the PPO applicable to your coverage.  Then access the PPO's website directly in order to search for a participating provider:
