ICD-10: R49.0

Dysphonia, classified under the ICD-10-CM code R49.0, refers to a disorder characterized by impaired voice quality, which can manifest as hoarseness, weakness, or changes in pitch. This condition can significantly affect an individual's ability to communicate effectively, impacting both personal and professional interactions.

Clinical Description of Dysphonia

Definition and Symptoms

Dysphonia is defined as a disturbance in the normal production of voice, which may include a variety of symptoms such as:
- Hoarseness: A raspy or strained voice quality.
- Weakness: A noticeable reduction in vocal strength.
- Altered Pitch: Changes in the usual pitch range, which may be higher or lower than normal.
- Breathiness: A voice that sounds airy or lacks clarity.

These symptoms can arise from various underlying causes, including but not limited to vocal cord nodules, laryngitis, neurological disorders, or even psychological factors such as stress or anxiety[1][2].

Etiology

The etiology of dysphonia can be multifactorial:
- Organic Causes: These include structural abnormalities of the vocal cords, such as nodules, polyps, or tumors, as well as inflammatory conditions like laryngitis.
- Neurological Disorders: Conditions such as Parkinson's disease or spasmodic dysphonia can lead to dysphonia due to impaired nerve function affecting voice production.
- Functional Causes: Voice misuse or overuse, often seen in professional voice users (e.g., singers, teachers), can lead to dysphonia without any identifiable organic cause[3].

Diagnosis

Diagnosis of dysphonia typically involves a thorough clinical evaluation, including:
- Patient History: Gathering information about the onset, duration, and nature of the voice changes.
- Physical Examination: A laryngoscopic examination may be performed to visualize the vocal cords and assess for any structural abnormalities.
- Voice Assessment: Speech-language pathologists may conduct voice assessments to evaluate the quality, pitch, and loudness of the voice[4].

Treatment Options

Treatment for dysphonia is tailored to the underlying cause and may include:
- Voice Therapy: Conducted by speech-language pathologists, this therapy focuses on vocal exercises and techniques to improve voice quality and reduce strain.
