Why is this important?
Texas Children’s Health Plan (TCHP) recognizes we may serve potentially impacted patients in our membership. We want to ensure that the member meets clinical evidence for treatment.
Next steps for providers: Prescribers should share this communication with their staff. Provider must submit documentation (such as office chart notes, lab results, or other clinical information) supporting that the member has met all approval criteria in support for Xenpozyme approval.
Note: If request is for a non-FDA approved dose or indication, medical rational must be submitted in support of therapy (such as high-quality peer reviewed literature, acceptable compendia or evidence based practice guidelines) and exceptions will be considered on a case-by-case basis.
