Apple Health (Medicaid) Provider Alert Attention providers: The Health Care Authority (HCA) has published a revised Kidney Center Services Billing Guide, effective February 19, 2025. HCA removed vaccines from the coverage table, which were inadvertently added to this billing guide. HCA has also added immunizations to the list of services not covered in kidney centers. For more information about vaccines, refer to the EPSDT Well-Child Program Billing Guide and the Physician-Related Services/Health Care Professional Services Billing Guide. See the What has changed? table in the revised guide for further details.
