Systemic antimicrobial therapy not prescribed (AOE)

CPT4 code

Name of the Procedure:

Systemic Antimicrobial Therapy Not Prescribed (AOE)


This is a clinical decision where doctors choose not to use systemic antibiotics for treating a specific condition, Acute Otitis Externa (AOE), often referred to as swimmer's ear. This approach focuses on topical treatments and other supportive measures instead.


The main purpose is to manage and treat AOE while minimizing the use of systemic antibiotics. The goals are to alleviate symptoms and prevent the unnecessary use of antibiotics which can lead to resistance.


  • Patients with mild to moderate acute otitis externa.
  • Patients who do not present with severe systemic symptoms such as fever.
  • Individuals without complications or conditions like diabetes or immunodeficiency that would necessitate systemic antibiotics.


No specific preparations are required for choosing not to prescribe systemic antibiotics. However, patients should be informed about proper ear hygiene and the use of prescribed topical treatments.

Procedure Description

There isn't a physical procedure involved. Instead, the focus is on:

  1. Educating the patient about the condition.
  2. Prescribing appropriate topical medications (e.g., antibiotic ear drops).
  3. Advising on pain management strategies such as over-the-counter pain relievers.
  4. Recommending protective measures to keep the ear dry.


The duration for this management strategy varies but typically involves a follow-up within 1-2 weeks to assess recovery.


This decision is made in a healthcare setting such as a primary care clinic or an ENT specialist's office.


Usually involves a primary care physician or an ENT specialist, and possibly a nurse to assist with patient education and follow-ups.

Risks and Complications

  • Failure to improve or worsening of symptoms.
  • Potential for reduced efficacy of topical treatments in some cases.
  • Need for systemic antibiotics if symptoms do not resolve or worsen.


  • Reduced risk of antibiotic resistance.
  • Avoidance of systemic side effects from antibiotics.
  • Typically quicker symptom relief with targeted topical treatment.


  • Follow the prescribed topical treatment regime.
  • Keep the ear dry and avoid inserting objects into the ear.
  • Follow-up with a healthcare provider typically after 1-2 weeks or sooner if symptoms worsen.


  • Systemic antibiotics, which might be used in severe cases or if topical treatment fails.
  • Other home remedies to relieve symptoms but generally less effective compared to medical treatments.

Patient Experience

Patients are encouraged to follow the recommendations for ear care and use of topical treatments. Mild discomfort or inconvenience might be felt but is generally manageable. Follow-up is crucial to ensure effective treatment and adjustment if necessary. Pain management information will be provided to ensure comfort.
