Influenza immunization recommended (COPD) (IBD)

CPT4 code

Name of the Procedure:

Influenza Immunization (Commonly known as a flu shot)


Influenza immunization is a vaccination procedure that helps protect against the influenza virus, commonly known as the flu. It is particularly recommended for individuals with chronic conditions like Chronic Obstructive Pulmonary Disease (COPD) and Inflammatory Bowel Disease (IBD) to prevent severe complications from the flu.


The purpose of influenza immunization is to reduce the risk of contracting the flu, which can lead to severe respiratory infections and complications, especially in individuals with chronic health conditions like COPD and IBD. The goal is to minimize flu-related hospitalizations and improve overall health outcomes.


  • Patients diagnosed with Chronic Obstructive Pulmonary Disease (COPD).
  • Patients diagnosed with Inflammatory Bowel Disease (IBD).
  • Individuals exhibiting symptoms such as chronic cough, shortness of breath, or frequent respiratory infections.
  • Criteria: Individuals aged 6 months and older, especially those with weakened immune systems or chronic health conditions.


  • No fasting required.
  • Inform your healthcare provider about any allergies or prior adverse reactions to vaccines.
  • Occasionally, a brief screening for current illnesses may be conducted to ensure the patient is not currently sick.

    Procedure Description

    1. The patient may sit or lie down.
    2. The healthcare provider cleans the injection site, usually the upper arm, with an antiseptic wipe.
    3. A sterile syringe with the influenza vaccine is prepared.
    4. The needle is inserted into the muscle, and the vaccine is administered.
    5. The injection site is covered with a small bandage.

No anesthesia or sedation is required for this procedure.


The procedure typically takes less than 5 minutes.


The influenza immunization is usually performed in an outpatient clinic, doctor's office, or a pharmacy.


  • Nurse or medical assistant
  • Physician or healthcare provider overseeing the vaccination program

Risks and Complications

  • Common: Pain, redness, or swelling at the injection site; low-grade fever; muscle aches.
  • Rare: Severe allergic reactions (anaphylaxis), Guillain-Barré Syndrome (GBS).


  • Reduced risk of contracting the flu.
  • Prevention of flu-related complications, especially in individuals with COPD and IBD.
  • Enhanced protection within 2 weeks post-vaccination.


  • Minimal post-procedure care is needed.
  • Patients can resume normal activities immediately.
  • Monitor for any signs of an allergic reaction (e.g., hives, difficulty breathing) and seek medical attention if they occur.
  • A follow-up may not be necessary unless experiencing adverse effects.


  • Antiviral medications: Used post-exposure but not as effective as prevention.
  • Nasal spray flu vaccine: An alternative for individuals without chronic conditions, though less frequently used in chronic disease patients.

Patient Experience

  • Mild discomfort during the injection.
  • Possible minor soreness at the injection site for a day or two.
  • Over-the-counter pain relievers and a warm compress can help manage discomfort.
  • Generally quick and minimally invasive with a high benefit-to-risk ratio.
