Things worth knowing about "H62.0"
H62.0 is the ICD-10 code for otitis externa in mycoses – a fungal infection of the outer ear canal causing itching, pain, and discharge.
What is H62.0 – Otitis Externa in Mycoses?
H62.0 is a diagnostic code from the ICD-10 classification system. It refers to otitis externa caused by mycoses, meaning an inflammation of the external ear canal caused by a fungal infection. This condition is also known as otomycosis. It primarily affects the outer ear canal and, in rare cases, the eardrum.
Causes
Otomycosis is most commonly caused by the following fungi:
- Aspergillus niger and other Aspergillus species (most frequent cause)
- Candida albicans and other Candida species
Predisposing factors include:
- Warm and humid climates or frequent swimming
- Prior antibiotic treatments that disrupt the natural microbial balance
- Weakened immune system or diabetes mellitus
- Perforated eardrum or previous ear surgery
- Excessive cleaning of the ear canal, which removes the protective earwax (cerumen)
Symptoms
Typical symptoms of H62.0 include:
- Intense itching in the ear canal (most common complaint)
- Ear pain or a feeling of pressure
- Discharge from the ear (otorrhea), often whitish, grayish, or blackish-green depending on the pathogen
- Sensation of fullness or reduced hearing
- Visible fungal growth or debris in the ear canal
Diagnosis
Diagnosis is typically established through:
- Otoscopy: direct visual examination of the ear canal using an otoscope
- Microbiological swab: collection of a sample for laboratory culture and identification of the fungal pathogen
- In uncertain cases, microscopic examination of secretions or fungal culture may be performed
Treatment
Treatment of otomycosis depends on the identified pathogen and includes:
Local (Topical) Treatment
- Antifungal ear drops or creams (e.g., containing clotrimazole, miconazole, or nystatin)
- Thorough cleaning and drying of the ear canal by an ENT specialist (e.g., suctioning or irrigation)
Systemic Treatment
- In severe or extensive infections, especially in immunocompromised patients, systemic antifungal therapy (e.g., fluconazole or itraconazole) may be required
General Measures
- Keep the ear dry and avoid getting water in the ear when bathing or swimming
- Avoid manipulation of the ear canal with cotton swabs
- Regular follow-up appointments with an ENT specialist
When to See a Doctor?
If you experience persistent ear pain, severe itching, discharge from the ear, or hearing loss, you should consult an ENT (ear, nose, and throat) specialist promptly. Early diagnosis and treatment prevent the spread of infection and potential complications such as damage to the eardrum.
