Unspecified voice and resonance disorder
ICD-10 R49.9 is a billable code used to indicate a diagnosis of unspecified voice and resonance disorder.
R49.9 refers to an unspecified voice and resonance disorder characterized by abnormalities in voice quality, pitch, loudness, or resonance that cannot be classified under more specific codes. Symptoms may include hoarseness, breathiness, or changes in vocal pitch, which can arise from various underlying conditions affecting the larynx, vocal cords, or neurological function. Common causes include laryngitis, vocal cord nodules, or neurological disorders such as Parkinson's disease. The disorder may present with signs such as altered voice quality, difficulty in phonation, or resonance changes, which can be assessed through clinical examination and laryngoscopy. Laboratory findings may include imaging studies or voice assessments to evaluate the structure and function of the vocal apparatus. Accurate diagnosis is essential for effective management and treatment, as the underlying cause can significantly influence the therapeutic approach.
Detailed history of voice changes, associated symptoms, and any prior treatments.
Patients presenting with chronic hoarseness or voice changes without a clear diagnosis.
Consider referral to ENT for further evaluation if symptoms persist.
Acute assessment of voice changes, including onset, duration, and associated respiratory symptoms.
Acute laryngitis or trauma to the vocal cords.
Rapid assessment is crucial; consider airway management if stridor or respiratory distress is present.
Used in conjunction with R49.9 for therapy sessions addressing voice disorders.
Document the specific voice issues being addressed and the treatment plan.
Speech therapy may be necessary for rehabilitation in cases of chronic voice disorders.
R49.9 should be used when a patient presents with voice and resonance disorders that do not fit into more specific categories, and when the underlying cause has not been determined.
