Recredentialing Process for Optometrist


The Caterpillar Healthcare PPO NetWork strives to ensure its members receive quality healthcare in an efficient and effective manner. The Caterpillar Healthcare PPO NetWork follows the Sate of Illinois single credentialing cycle, which is based on the last digit of the provider’s Social Security number.

When a provider is eligible for recredentialing, the provider office will be notified by letter sent to the primary office location listed in the credentialing file. Within 30 days of notification, the provider must return a copy of the letter received from Caterpillar with all of the required documentation listed below.

Failure to complete recredentialing may result in termination from the Caterpillar Healthcare PPO NetWork.
