Unspecified disturbances of smell and taste
ICD-10 R43.9 is a billable code used to indicate a diagnosis of unspecified disturbances of smell and taste.
R43.9 refers to unspecified disturbances of smell and taste, which can manifest as a reduced ability to detect odors (hyposmia), complete loss of smell (anosmia), altered taste perception (dysgeusia), or loss of taste (ageusia). These disturbances can arise from various underlying conditions, including viral infections (such as COVID-19), neurological disorders (like Parkinson's disease), head trauma, or exposure to certain medications. The symptoms may present as a gradual decline or sudden onset, often affecting the quality of life and nutritional intake of the patient. Clinical evaluation typically involves a thorough history and physical examination, with additional tests such as olfactory testing or imaging studies if indicated. The lack of specificity in this code necessitates careful documentation to ensure accurate coding and billing.
