How this impacts providers: Genetic Testing Requirements
- Prior authorization is required for all genetic testing, except:
- Cystic Fibrosis Screening
- Spinal Muscular Atrophy Screening
- This applies even when testing is done by an in-network lab such as Quest Diagnostics.
- Prior authorization requests: In-network providers should access Texas Children’s® Link, provider portal to complete the necessary steps.
- Other providers should complete the Standard Prior Authorization Form and follow the guidance available here: Prior Authorization Information | Texas Children's Health Plan.
Next step for Providers: Providers should share this communication with their staff.
