H80: Otosclerosis

H80 refers to Otosclerosis, which includes conditions affecting the bony structures of the ear (e.g., otosclerosis), the vestibular system responsible for balance (e.g., vertigo, Meniere’s disease), or broader inner ear pathology. These disorders often result in hearing loss, dizziness, or coordination issues and may significantly affect quality of life.

Symptoms

• Progressive hearing loss – Characteristic of otosclerosis (H80)
• Vertigo and dizziness – Core symptoms of vestibular disorders (H81–H82)
• Ringing in the ears (tinnitus) – Frequently associated with inner ear conditions
• Imbalance or unsteady gait – Found in H81 vestibular dysfunction
• Aural fullness or ear pressure – Seen in Meniere’s disease (H81.0)
• Sudden sensorineural hearing loss – May occur in H83 categories
• Nausea or vomiting – Secondary to vestibular disturbances

Diagnosis

Diagnosis of Otosclerosis involves audiometry, tympanometry, CT or MRI (for structural or vestibular pathology), ENG/VNG (for vestibular function), and vestibular evoked myogenic potentials. Medical history and symptom provocation tests also guide diagnosis.

ICD10 Code Usage

ICD10 code H80 is used by ENT specialists, audiologists, and neurologists. It supports clinical documentation for surgical planning (e.g., stapedectomy in otosclerosis), vestibular rehabilitation, medication authorization, and disability assessment due to chronic dizziness or hearing loss.

Related Codes

• H81 – Disorders of vestibular function
• H82 – Vertiginous syndromes in diseases classified elsewhere
• H83 – Other diseases of inner ear

FAQs

Q1: What is ICD10 code H80?
A: It documents Otosclerosis, referring to hearing and balance disorders originating in the bony, sensory, or fluid systems of the inner ear.

Q2: Is otosclerosis treatable?
A: Yes, with hearing aids or surgical procedures like stapedectomy to restore sound conduction.

Q3: What are examples of vestibular disorders (H81)?
A: Benign paroxysmal positional vertigo (BPPV), vestibular neuritis, and Meniere’s disease.

Q4: What is coded under H82?
A: Vertiginous conditions resulting from systemic illness such as syphilis, multiple sclerosis, or autoimmune diseases.

Q5: Who treats these conditions?
A: ENT specialists, audiologists, neurologists, vestibular physiotherapists, and otologists depending on the cause.

Conclusion

ICD10 code H80 provides a framework to classify, diagnose, and manage Otosclerosis, ensuring appropriate referral, rehabilitation, and medical or surgical care to address auditory and balance-related dysfunctions.
