Moderna COVID-19 booster: codes for new dose option

There are new codes for Moderna’s COVID-19 vaccine booster after the Food and Drug Administration amended the shot’s emergency use authorization on March 29:

  • 91309: Severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) (coronavirus disease [COVID-19]) vaccine, mRNA-LNP, spike protein, preservative free, 50 mcg/0.5 mL dosage, for intramuscular use,
  • 0094A: Immunization administration by intramuscular injection of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) (coronavirus disease [COVID-19]) vaccine, mRNA-LNP, spike protein, preservative free, 50 mcg/0.5 mL dosage, booster dose.

The codes, which are recognized by the Centers for Medicare & Medicaid Services (CMS), reflect a new dosage option (the previous Moderna booster, a 50 mcg/0.25 mL dose, can still be reported with CPT code 91306). The new booster is a higher-volume dose than the previous one, but provides the same 50 micrograms mRNA (which is half that in the primary series shots). Moderna booster shots were previously given out of the same red-topped vials as primary shots, just in a half-dose. The new formulation will come in a blue-topped vial for booster shots only.
