Things worth knowing about "H90.3"

H90.3 is an ICD-10 diagnosis code for bilateral conductive hearing loss, a condition where sound transmission to the inner ear is impaired in both ears, reducing hearing ability.

Definition

H90.3 is a diagnostic code from the International Classification of Diseases (ICD-10) referring to bilateral conductive hearing loss. In this type of hearing loss, the mechanical transmission of sound through the outer ear canal, eardrum, or the ossicles (small bones) of the middle ear to the inner ear is impaired on both sides.

Causes

Conductive hearing loss can result from various factors that obstruct or disrupt the mechanical transmission of sound:

Earwax blockage (cerumen impaction): Accumulation of earwax blocking the ear canal
Middle ear infection (otitis media): Inflammation of the middle ear, often accompanied by fluid buildup
Otitis media with effusion (glue ear): Fluid accumulation behind the eardrum without active infection
Eardrum perforation: A hole or tear in the tympanic membrane
Otosclerosis: Abnormal bone growth in the middle ear restricting ossicle mobility
Congenital malformations: Birth defects of the outer or middle ear
Foreign bodies: Objects lodged in the external ear canal

Symptoms

Common symptoms of bilateral conductive hearing loss include:

Reduced perception of sound volume in both ears
A sensation of fullness or blockage in the ears
Difficulty understanding speech, especially in noisy environments
Autophony (hearing one's own voice unusually loudly)
Occasional ear pain or pressure

Diagnosis

Diagnosis of conductive hearing loss is made by an ear, nose, and throat (ENT) specialist using the following methods:

Otoscopy: Direct visual examination of the ear canal and eardrum using an otoscope
Tuning fork tests (Weber and Rinne tests): Simple bedside tests to differentiate conductive from sensorineural hearing loss
Pure-tone audiometry: Measurement of hearing across different frequencies; conductive hearing loss shows an air-bone gap with preserved bone conduction
Tympanometry: Assessment of eardrum mobility to evaluate middle ear function

Treatment

Treatment depends on the underlying cause:

Earwax removal: Professional irrigation or microsuction of impacted cerumen by an ENT specialist
Medical therapy: Antibiotics or decongestants for middle ear infections
Myringotomy and tympanostomy tubes: A small incision in the eardrum to drain middle ear fluid, often with insertion of ventilation tubes
Surgical procedures: Such as tympanoplasty (eardrum reconstruction) or stapedectomy for otosclerosis
Hearing aids: For permanent or irreversible hearing loss when surgical correction is not possible
Bone-anchored hearing systems (BAHA): For more severe cases or structural malformations of the ear

Prognosis

The prognosis for conductive hearing loss is generally favorable, as the underlying cause is often treatable. With timely and appropriate intervention, hearing can frequently be fully or largely restored. If left untreated, bilateral hearing loss can significantly impact daily functioning and, in children, may lead to delays in speech and language development.
