H61.2 is the ICD-10 code for impacted cerumen, commonly known as an earwax blockage. It describes an abnormal accumulation of earwax in the ear canal.
What is H61.2?
The ICD-10 code H61.2 refers to impacted cerumen, commonly known as an earwax blockage or ceruminal plug. This condition occurs when cerumen (earwax) accumulates excessively in the external ear canal, causing a partial or complete obstruction.
Earwax is a natural and protective substance produced by glands in the skin of the ear canal. Under normal circumstances it plays a vital role in cleaning, moisturising, and protecting the ear from bacteria and foreign particles. Problems arise only when earwax builds up to the point where it blocks the ear canal.
Causes
Several factors can contribute to the development of impacted cerumen:
- Overproduction of earwax: Some individuals naturally produce more cerumen than others.
- Narrow ear canal: An anatomically narrow canal makes it harder for earwax to migrate outward naturally.
- Improper ear cleaning: Using cotton swabs can push earwax deeper into the canal rather than removing it.
- Hearing aids or in-ear headphones: Regular use can interfere with the natural self-cleaning mechanism of the ear.
- Age: Earwax tends to become drier and harder with age, increasing the risk of blockage.
- Occupational exposure: Frequent contact with dust or particulates may contribute to plug formation.
Symptoms
An earwax blockage may cause the following symptoms:
- Hearing loss or a feeling of blocked ears
- Ear pain or a sensation of pressure in the ear
- Tinnitus (ringing or buzzing in the ear)
- Dizziness or balance problems (less common)
- Itching inside the ear canal
- Reflex cough due to stimulation of the vagus nerve (rare)
Diagnosis
Impacted cerumen (ICD-10: H61.2) is typically diagnosed through otoscopy, a direct examination of the ear canal using an otoscope. This allows the clinician to visualise the accumulated earwax clearly. No further diagnostic tests are usually required.
Treatment
There are several effective approaches to treating an earwax blockage:
Ear irrigation
Ear irrigation involves flushing the ear canal with warm water or saline solution under gentle pressure to dislodge and remove the earwax. This procedure should only be performed when the eardrum is intact.
Cerumenolytic ear drops
Cerumenolytic drops contain softening agents such as glycerol, almond oil, or hydrogen peroxide. They help dissolve and soften the earwax, making it easier to remove. They are often used in preparation for irrigation.
Manual removal
In an ear, nose and throat (ENT) clinic, the plug can be removed mechanically using specialised instruments such as a curette (a small scooping instrument) or suction devices.
Prevention
To prevent earwax buildup, it is advisable to avoid inserting cotton swabs or other objects into the ear canal. People who are prone to recurrent blockages may benefit from using cerumenolytic drops regularly as a preventive measure.
