Official Description

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (coronavirus disease [COVID-19]) vaccine, mRNA-LNP, spike protein, bivalent, preservative free, 50 mcg/0.5 mL dosage, for intramuscular use

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 91313 refers to a specific vaccine designed to provide immunity against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is responsible for the disease known as coronavirus disease (COVID-19). This vaccine utilizes a bivalent formulation, meaning it contains messenger RNA (mRNA) components that correspond to both the original strain of the virus and a variant strain associated with the omicron variant, specifically targeting the BA.4 and BA.5 subvariant lineages. The vaccine is preservative-free and is administered in a dosage of 50 mcg per 0.5 mL via intramuscular injection. The mechanism of action involves the use of lipid nanoparticles (LNP) to encapsulate the mRNA, allowing it to be delivered effectively into the body's cells. Once inside, the cells utilize the mRNA as a template to produce the spike protein found on the surface of the coronavirus. This process triggers an immune response, prompting the body to generate antibodies that can recognize and combat the virus if the individual is exposed in the future. The vaccine is intended for individuals aged 18 years and older who have previously received COVID-19 vaccinations, serving as a booster to enhance their immune protection. It is important to note that while this code reports the supply of the vaccine, the actual administration of the vaccine is documented separately using the appropriate administration code.

1. Indications

The CPT® Code 91313 is indicated for the administration of the bivalent COVID-19 vaccine to provide enhanced protection against the SARS-CoV-2 virus and the associated disease, COVID-19. This vaccine is specifically recommended for individuals who meet the following criteria:

  • Age Requirement: Individuals aged 18 years and older.
  • Prior Vaccination: Patients who have already been vaccinated against COVID-19 and are in need of a booster dose to strengthen their immune response.

2. Procedure

The procedure for administering the CPT® Code 91313 vaccine involves several key steps to ensure proper delivery and effectiveness of the vaccine:

  • Step 1: Preparation of the Vaccine The vaccine should be prepared in accordance with the manufacturer's guidelines. This includes checking the expiration date, ensuring the vaccine is at the appropriate temperature, and gently swirling the vial to mix the contents without shaking, which could damage the mRNA.
  • Step 2: Patient Assessment Prior to administration, the healthcare provider must assess the patient’s vaccination history to confirm eligibility for the booster dose. This includes verifying that the patient is at least 18 years old and has received prior COVID-19 vaccinations.
  • Step 3: Administration of the Vaccine The vaccine is administered via intramuscular injection, typically in the deltoid muscle of the upper arm. The injection site should be cleaned with an alcohol swab to minimize the risk of infection. The healthcare provider should use a sterile syringe and needle to draw up the vaccine and administer it in a single, swift motion to ensure patient comfort.
  • Step 4: Post-Administration Monitoring After the injection, the patient should be monitored for a short period to observe for any immediate adverse reactions. This is typically done for 15 to 30 minutes, especially for individuals with a history of allergic reactions to vaccines.

3. Post-Procedure

Following the administration of the CPT® Code 91313 vaccine, patients are advised to monitor for any side effects, which may include soreness at the injection site, fatigue, headache, muscle pain, chills, fever, or nausea. These side effects are generally mild and resolve within a few days. Patients should be informed about the importance of completing the vaccination series and encouraged to report any unusual or severe reactions to their healthcare provider. Additionally, individuals should continue to follow public health guidelines regarding COVID-19, including mask-wearing and social distancing, as appropriate, even after vaccination.
