Official Description

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (coronavirus disease [COVID-19]) vaccine, mRNA-LNP, bivalent spike protein, preservative free, 10 mcg/0.2 mL dosage, diluent reconstituted, tris-sucrose formulation, for intramuscular use

Common Language Description

The CPT® Code 91315 refers to a specific formulation of the COVID-19 vaccine designed to provide immunity against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is responsible for the disease known as COVID-19. This vaccine utilizes a bivalent approach, meaning it contains messenger RNA (mRNA) components that correspond to both the original strain of the virus and the omicron variant, specifically targeting the BA.4 and BA.5 subvariant lineages. The vaccine is preservative-free and is delivered in a dosage of 10 mcg per 0.2 mL, which is suitable for intramuscular administration. The mRNA is encapsulated in lipid nanoparticles (mRNA-LNP), allowing for effective delivery into the body's cells. Upon administration, the cells utilize the mRNA to produce the viral spike protein, which is recognized by the immune system as foreign, prompting the production of antibodies. This immune response is crucial for protecting individuals from severe illness upon exposure to the virus. The vaccine is specifically indicated for children aged 5 through 11 years who have previously received COVID-19 vaccinations. It is important to note that the preparation of this vaccine involves diluting it with preservative-free normal saline to achieve the correct dosage for pediatric patients. The TRIS-sucrose formulation includes buffering agents that help stabilize the vaccine and maintain its pH, ensuring its efficacy and safety when administered.

1. Indications

The CPT® Code 91315 is indicated for the following:

  • COVID-19 Vaccination This vaccine is specifically designed to provide protection against the SARS-CoV-2 virus, which causes COVID-19, particularly in children aged 5 through 11 years who have already been vaccinated against the disease.

2. Procedure

The administration of the COVID-19 vaccine under CPT® Code 91315 involves several key procedural steps:

  • Preparation of the Vaccine The vaccine is prepared by diluting the bivalent mRNA-LNP formulation with preservative-free normal saline to achieve the appropriate dosage of 10 mcg per 0.2 mL for pediatric patients. This step is crucial to ensure that the vaccine is safe and effective for administration.
  • Intramuscular Injection Once prepared, the vaccine is administered via intramuscular injection. This method allows for optimal absorption of the mRNA-LNP into the muscle tissue, facilitating the uptake of the mRNA by the body’s cells. The injection site is typically the deltoid muscle in the upper arm for children.
  • Monitoring Post-Administration After the injection, patients are usually monitored for a short period to observe for any immediate adverse reactions. This is a standard practice to ensure patient safety following vaccination.

3. Post-Procedure

Post-procedure care for the administration of the COVID-19 vaccine under CPT® Code 91315 includes monitoring for any potential side effects, which may include mild reactions such as soreness at the injection site, fatigue, or low-grade fever. Patients and caregivers are advised to report any unusual or severe reactions to healthcare providers. It is also important to inform patients about the need for follow-up vaccinations as per the recommended vaccination schedule to ensure continued protection against COVID-19.
