Dysphonia
ICD-10 R49.0 is a billable code used to indicate a diagnosis of dysphonia.
Dysphonia refers to a disorder of the voice characterized by abnormal vocal quality, pitch, loudness, or resonance. It can manifest as hoarseness, breathiness, or a strained voice, and may be temporary or chronic. Dysphonia can arise from various underlying conditions, including laryngeal pathologies, neurological disorders, or systemic diseases. Common causes include acute laryngitis, vocal cord nodules, and neurological conditions such as Parkinson's disease. The clinical presentation may vary widely, with patients reporting difficulty in speaking, changes in voice quality, or pain during phonation. A thorough history and physical examination, including laryngeal examination, are essential for diagnosis. Dysphonia is often evaluated through laryngoscopy, which allows visualization of the vocal cords and surrounding structures. Treatment may involve voice therapy, medical management, or surgical intervention depending on the underlying cause.
Detailed history of voice changes, associated symptoms, and any relevant medical history.
Patients presenting with hoarseness due to upper respiratory infections or chronic cough.
Consideration of systemic diseases that may contribute to dysphonia, such as thyroid disorders.
Acute assessment of voice changes, including onset, duration, and associated symptoms.
Acute laryngitis or trauma to the neck resulting in sudden dysphonia.
Rapid evaluation for potential airway compromise in acute settings.
Used to evaluate the vocal cords in patients presenting with dysphonia.
Document indication for laryngoscopy and findings.
ENT specialists often perform this procedure.
Dysphonia refers to impaired voice quality, while aphonia is the complete loss of voice. Dysphonia can be characterized by hoarseness or changes in pitch, whereas aphonia indicates an inability to produce sound.
