Question: Oregon Subscriber Answer: For instance: In other cases, some state agencies may choose to pay one of the new codes but not the other. The Tennessee Vaccines for Children (VFC) Program maintains its own rules for reporting immunizations, and does not include recognition of new code 90461. "Providers are encouraged to use the new code 90460 for the administration of a vaccine under the VFC program," the organization's Web site notes. "If code 90461 is used for a vaccine with multiple antigens or components, it should be given a $0 value for a child covered under the VFC program. This applies to both Medicaid-enrolled VFC-entitled children as well as non-Medicaid-enrolled VFC-entitled children." You can read the statement in its entirety at www.bcbst.com/providers/bluecare-tenncareselect/VFC_Vax_Admin_CPT_guidance.pdf. These individual state Medicaid inconsistencies make providing immunizations for children on the Medicaid Vaccine for Children program difficult. However, this struggle is nothing new for pediatric offices. Given Medicare guidelines to the state programs, it is unlikely your state will be adopting the new 90460-90461 series at this time.
