Name of the Procedure:

Influenza Immunization Administered or Previously Received (HCPCS Code G8482)
Common Name: Flu Shot
Technical/Medical Term: Influenza Vaccination

Summary

An influenza immunization, commonly known as a flu shot, is a vaccine administered to protect against the influenza virus. It involves an injection into the muscle, typically in the upper arm.

Purpose

The flu shot aims to prevent the influenza virus, which can cause mild to severe respiratory illnesses. The goal is to reduce the incidence of flu, prevent serious complications, and limit the spread of the virus in the community.

Indications

• Annual vaccination is recommended for everyone aged six months and older.
• Especially important for high-risk groups such as the elderly, young children, pregnant women, and individuals with chronic health conditions.
• Those in close contact with high-risk groups are also strongly recommended to get vaccinated.

Preparation

• No significant preparation required.
• Inform the healthcare provider about any allergies, especially to eggs, since some vaccines contain egg protein.
• No fasting or special medication adjustments are usually necessary.

Procedure Description

1. The healthcare provider will clean the injection site with an antiseptic.
2. A pre-filled syringe containing the influenza vaccine will be prepared.
3. The vaccine is injected into the muscle of the upper arm using a needle.
4. A bandage may be applied to the site, and the patient is observed for a few minutes for any immediate reactions.

Tools and Equipment:

• Pre-filled influenza vaccine syringe
• Antiseptic solution
• Needle
• Bandage

No anesthesia or sedation is required for this procedure.

Duration

The injection itself takes only a few minutes. Including preparation and observation, the entire process typically takes about 10-15 minutes.

Setting

The flu shot can be administered in various settings, including:

• Doctor's office
• Outpatient clinics
• Pharmacies
• Community health centers

Personnel

• Usually administered by a nurse, pharmacist, or other trained healthcare provider.

Risks and Complications

• Common: Soreness at the injection site, mild fever, fatigue, and muscle aches.
• Rare: Allergic reactions or Guillain-Barré syndrome. Immediate medical attention is available to manage adverse reactions.

Benefits

• Significantly reduces the risk of contracting influenza.
• Helps prevent severe illness, hospitalization, and death.
• Protection typically begins within two weeks after the vaccination.

Recovery

• Most people can resume their normal activities immediately after the shot.
• A sore arm or mild flu-like symptoms may be experienced for a day or two.
• No significant recovery time required; follow-up appointments are typically unnecessary unless complications arise.

Alternatives

• Nasal spray vaccine (for certain age groups and health conditions).
• The pros of the flu shot include its suitability for a wide range of individuals and its broad distribution. Nasal spray may be an option for those averse to injections but has more restrictions.

Patient Experience

• During: Mild discomfort from the injection.
• After: Possible muscle soreness and minor side effects like a low-grade fever or tiredness. Over-the-counter pain relievers and cold compresses can help manage symptoms.
