  •   *ICD-10-CM code Z23, Encounter for Immunization, is reported for all vaccines given within an encounter; additional ICD-10-CM coding may be needed.2
  •   Note that some payers require an 11-digit NDC, which involves adding a "0" immediately after the first hyphen in each GSK NDC.6 For example, when reporting NDC 58160-848-11 to TRICARE, it becomes NDC 58160-0848-11.
