H90.2 Conductive hearing loss, unspecified

Name of the Condition

• Conductive Hearing Loss, Unspecified (ICD-10 Code: H90.2)

Summary

Conductive hearing loss, unspecified, refers to a reduction in hearing ability caused by problems in the outer or middle ear that impede sound transmission to the inner ear. This type of hearing loss typically affects the ability to hear faint or soft sounds and may involve issues such as blockages, infections, or structural abnormalities in the ear canal or middle ear.

Causes

Conductive hearing loss may result from blockages in the ear canal, middle ear infections, fluid accumulation, or structural abnormalities in the middle ear bones. Other potential causes include perforated eardrums, benign growths, or congenital malformations affecting the ear.

Risk Factors

• Recurrent ear infections or otitis media.
• Exposure to loud noises that may contribute to ear damage.
• Age-related changes in the middle ear.
• History of ear trauma or surgery.
• Presence of foreign objects or wax buildup in the ear canal.

Symptoms

• Muffled or distorted hearing.
• Difficulty hearing soft sounds or speech.
• Sensation of fullness or pressure in the ear.
• Possible ear pain or discharge if an infection is present.

Diagnosis

Diagnosis involves a combination of physical examination by an ENT specialist, audiometric tests to assess hearing levels, and imaging studies (e.g., MRI or CT scan) to rule out structural causes. Additional tests may include tympanometry to evaluate middle ear function.

Treatment Options

• Medications to treat infections or reduce inflammation.
• Surgical procedures to repair structural abnormalities or remove blockages.
• Hearing aids to amplify sounds if needed.
• Management of underlying conditions such as allergies or fluid buildup.

Prognosis and Follow-Up

Prognosis depends on the underlying cause and timely intervention. Many cases of conductive hearing loss can be treated effectively, especially when caused by infections or blockages. Follow-up care may include regular hearing assessments and monitoring for recurrence of symptoms.

Complications

• Persistent hearing loss if untreated.
• Chronic ear infections or fluid buildup.
• Delayed speech or language development in children.
• Increased risk of balance issues if the inner ear is affected.

Lifestyle & Prevention

• Avoid inserting objects into the ear canal to prevent blockages or injury.
• Manage allergies and respiratory infections promptly to reduce ear congestion.
• Use hearing protection in noisy environments.
• Maintain good ear hygiene and seek prompt care for ear pain or discharge.

When to Seek Professional Help

Seek medical attention if you experience sudden or worsening hearing loss, persistent ear pain, discharge, or dizziness. Early evaluation is important to identify and address underlying causes.

Tips for Medical Coders

When coding for conductive hearing loss, unspecified (H90.2), ensure documentation supports the absence of laterality (unilateral or bilateral) or specific ear involvement. Verify that the diagnosis aligns with clinical findings and that no more specific code (e.g., unilateral or bilateral) is applicable based on the patient's condition.
