Manual and Forms

Doctor Reading Manual

The Provider Manual is a comprehensive reference guide for our products, value-added programs and services. Our hope is that this will make it easier for you and your staff to collaborate with us in providing excellent service to your Cook Children's Health Plan patients.

Updating Provider Information

Providers must inform the health plan of any changes to their contact information including address, telephone and fax number, group affiliation, etc. It is also important to submit any updates to your panel status such as changing from a closed panel to an open panel as well as any changes to age restrictions. Providers must also ensure that the Health Plan has current billing information on file to facilitate accurate payment delivery.

Providers may submit demographic changes via our Secure Provider Portal or by completing the Provider Information Change Form located on our Provider Forms webpage. Email the change form to our Network Development team at

Providers must also communicate changes to Texas Medicaid & Healthcare Partnership (TMHP). The TMHP Provider Information Management System (PIMS) User Guide (PDF) provides guidance on submitting demographic updates to TMHP. Providers can locate more information about TMHP Provider Information Management System (PIMS) on

In the event of an outage contact Provider Relations at 888-243-3312 or
