ICD-10: H60.311

The ICD-10 code H60.311 refers specifically to "Diffuse otitis externa, right ear." Here are some alternative names and related terms associated with this condition:

• Diffuse Otitis Externa: This is the primary term used to describe the condition, which indicates inflammation of the external ear canal.
• Right Ear Otitis Externa: This term specifies the location of the condition, indicating that it affects the right ear.
• External Ear Infection: A more general term that can encompass various types of infections affecting the outer ear, including diffuse otitis externa.
• Swimmer's Ear: A common colloquial term for otitis externa, particularly when it is caused by water exposure, although it may not specifically refer to the diffuse type.
• H60.31: This is the broader category code for diffuse otitis externa, which includes other variations such as left ear (H60.312) and bilateral (H60.313) otitis externa.

These terms help in understanding the condition and its classification within medical coding systems, particularly in the context of ear diseases as outlined in the ICD-10 coding framework [2][6][9].

The diagnosis of diffuse otitis externa, specifically coded as H60.311 in the ICD-10 system, involves several criteria that healthcare professionals typically consider:

1. Clinical Symptoms: The patient usually presents with symptoms such as:
   - Inflammation of the outer ear and ear canal.
   - Redness and swelling in the affected area.
   - Possible discharge from the ear, which may be purulent.

2. History of Symptoms: The duration and progression of symptoms are important. Acute cases may develop rapidly, while chronic cases may have a longer history of recurrent symptoms.

3. Physical Examination: A thorough examination of the ear is conducted, which may reveal:
   - Tenderness upon palpation of the outer ear.
   - Visible signs of inflammation in the ear canal.
   - Presence of debris or discharge.

4. Exclusion of Other Conditions: It is essential to rule out other potential causes of ear symptoms, such as:
   - Eczema or dermatitis affecting the ear.
   - Fungal infections or other types of otitis externa (e.g., otitis externa hemorrhagica).

5. Diagnostic Tests: While not always necessary, tests may be performed to confirm the diagnosis, including:
   - Swabs for culture to identify any bacterial or fungal pathogens.
   - Audiometric tests if hearing loss is reported.

6. Response to Treatment: The diagnosis may also be supported by the patient's response to initial treatment, such as topical antibiotics or corticosteroids, which can help alleviate symptoms.

These criteria help ensure that the diagnosis of diffuse otitis externa is accurate and that appropriate treatment can be initiated.
