Cook Children's specialty care services

At Cook Children's, we provide more than 60 pediatric medical and specialty clinic offices throughout Texas.

Continued care

Referrals

• Referrals to a specialist may be made by your doctor. However, no referrals are made until your child has been seen by his or her primary care physician.
• If you are a member of a managed care plan (HMO), a referral form is required for treatment by a specialist. Allow five to seven working days for the referral to be completed and mailed.

After-hours calls

• After office hours, your call will be answered automatically by our answering service. A message will be taken and transferred to the Cook Children's Health Care System nurse triage system. A nurse will return your call as soon as possible, usually within the hour, to offer input about your child's symptoms. In cases of emergency, your pediatrician will be contacted.
• Please limit after-hours calls to those that you feel are truly urgent. Feeding questions, prescription refills or appointment requests are not considered appropriate after-hours calls. Colds, congestion and constipation generally do not warrant after-hours calls.
