Frequently Asked Questions (FAQs) and Resources


Will my Insurance Cover my Appointment?

The best way to determine whether or not your insurance provider will provide coverage for your appointment is to contact them directly. Especially if you require travel to our clinic.

Some information you might find useful in communicating with your insurance provider include:

  • the name of the providers who will likely see your child in clinic
  • the possible billing codes that could apply to your visit
  • Your child’s diagnosis code
  • If pre-authorization is required by your insurance company (may take several weeks)
While billing codes are determined at the time of the appointment and we cannot guarantee which services will be provided and which codes will be submitted for billing, the codes listed below are commonly used in our clinic. In addition, our office typically confirms your insurance coverage a few days prior to your appointment as well, however we encourage you to call your insurance company in advance, especially if you are going to be planning travel for your appointment.
Some insurance companies may require pre-authorization, which can take several weeks for our office to process and we will need to know in advance. Pre-authorization of coverage and benefits by your insurance company does not always mean the insurance company will pay for the services. Sometimes an insurance company will pre-authorize a service, however then not pay for the visit.  Any portion of the bill which is not covered by your insurance is ultimately your responsibility.  Children’s Hospital Colorado will help you set up a payment plan if needed. Listed below are the billing codes most commonly used in our clinic.

Can my child be seen in clinic if I don’t have insurance?

If you do not have health insurance or other financial assistance, please call the hospital at (720) 777-6422 and ask for Financial Aid. We can help determine eligibility for financial aid programs that are available to you.
If you need to self-pay for the appointment(s), contact our cost estimation team at 720-777-0720 and discuss with them what the possible costs may be in seeing our team.

Can my child be seen in clinic if s/he has Medicaid outside of Colorado?

If your child has Medicaid from another state, coverage will need to be determined based on if your home state Medicaid is contracted with our hospital.  You can contact your local Medicaid office or please call our department at 720-777-6630 and inquire if our hospital and providers are contracted with your local Medicaid insurance provider to determine eligibility for coverage.

Can my child is now an adult, will you see him/her?

While we would love to be able to see all ages, unfortunately our providers are licensed to evaluate pediatric patients.  However, we are working diligently to build a collaborating team with adult providers both locally and nationally.  So you are welcome to contact us or the national support group to try to identify an adult provider or team that would be the best fit for your needs. 

Is there a clinic like the eXtraordinarY Kids Clinic closer to my home?

If you are seeking a clinic for your child closer to your home, we encourage you to visit the AXYS website to determine if there is a closer clinic to your home:

I am looking for more information about prenatal screening or testing for X&Y Chromosome Variations, can your clinic help me?

We have many patients who call our clinic and schedule an appointment to better understand their screening or test results during pregnancy.  Please note, screening results are not diagnostic, and therefore diagnostic testing is recommended (either before or after pregnancy) to confirm if the child does in fact have an X&Y chromosome variation, as there can be false positives from screening.
Diagnostic testing during pregnancy is either done by chorionic villus sampling (CVS) or amniocentesis.  The results from these tests can determine if in fact the fetus has an X&Y chromosome variation, as these tests are chromosome tests. Talk with your doctor to determine which test may be right for you.   
Diagnostic testing can also be pursued after the baby is born. The easiest way to do this for a newborn is to request your doctor do this test on a blood sample taken from the umbilical cord, also called “cord blood”at the time of the baby’s delivery.
In addition, there are some valuable resources available to help patients understand genetic screening and testing and X&Y chromosome variations during pregnancy. Some resources on YouTube are:


How can my child get tested to determine if s/he has an X&Y Chromosome Variation?

X&Y chromosome variations are diagnosed from chromosome tests, commonly known as a karyotype or a microarray, which are typically done on a blood sample, but can also be done on skin as well.  Many types of doctors, including pediatricians, are comfortable ordering these tests, so talk with your doctor to determine if testing is available through their office.

My child has an X&Y Chromosome Variation. Now what?

For reasons we don’t completely understand, there is significant variability among children with X&Y chromosome variations. Some will not have many symptoms while others may have several. Often children with X&Y chromosome variations don’t look significantly different from their peers. Symptoms that can be seen in these conditions can include medical problems, developmental delays, learning disabilities and social-emotional difficulties.
Babies diagnosed prenatally or during infancy with an X&Y chromosome variation should be monitored closely during early developmental years (birth to 5), including standardized developmental assessments to determine if early interventions are needed. Children with an X&Y chromosome variation should have neuropsychological testing during early academic years to monitor for learning disabilities, attentional problems, and social/emotional concerns. Boys with extra X chromosomes need to be seen by an endocrinologist during puberty to help monitor their testosterone levels.
Our clinic can evaluate your child for the various symptoms associated with their diagnosis and provide you with additional information about their diagnosis.
Additional information about the various X&Y chromosome variations can also be found at
