The new codes are based on a tris-sucrose buffer rather than the phosphate buffer present in the original formulation.
The CPT code for Pfizer’s tris-sucrose buffer COVID-19 vaccine is 91305. It also has CPT codes for the administration of three doses: 0051A, 0052A and 0053A.
The tris-sucrose buffer formulation has not yet received approval from the FDA. The new codes will be effective for use once and if the approval is granted.
