Hypernasality and hyponasality
ICD-10 R49.2 is a billable code used to indicate a diagnosis of hypernasality and hyponasality.
Hypernasality and hyponasality refer to abnormal resonance of speech due to improper airflow through the nasal cavity during phonation. Hypernasality occurs when there is excessive nasal resonance, often due to conditions such as cleft palate, nasal obstruction, or neurological disorders affecting the soft palate. Hyponasality, on the other hand, is characterized by insufficient nasal resonance, commonly seen in conditions like nasal congestion or structural abnormalities of the nasal passages. Both conditions can significantly impact speech intelligibility and quality of life. Clinically, these symptoms may be assessed through perceptual evaluation, nasometry, or instrumental assessments like videofluoroscopy. The underlying causes can vary widely, necessitating a thorough clinical evaluation to determine the appropriate management and treatment strategies.
Detailed history of symptoms, physical examination findings, and any relevant lab results.
Patients presenting with chronic nasal congestion leading to hyponasality.
Consideration of systemic conditions that may contribute to nasal obstruction.
Acute assessment of airway and breathing, including any immediate interventions.
Acute allergic reactions causing sudden onset of nasal obstruction.
Rapid assessment and documentation of airway status are critical.
Used in conjunction with R49.2 for speech therapy services.
Document the specific speech therapy interventions provided.
Ensure that the therapy is directly related to the diagnosis of hypernasality or hyponasality.
Hypernasality refers to excessive nasal resonance during speech, while hyponasality indicates insufficient nasal resonance, often due to nasal obstruction or structural issues.
