Unspecified disturbances of smell and taste

This code signifies a general impairment of the chemosensory system, affecting either the ability to smell (olfaction) or taste (gustation), or both, without further specification of the type or cause of the disturbance. It indicates that the patient is experiencing an alteration in these senses, but the precise nature or etiology is not documented.

Use this code when documentation indicates a patient reports or is diagnosed with a disturbance of smell or taste, but the medical record lacks specific details regarding the type (e.g., anosmia, ageusia, dysgeusia, phantosmia) or the underlying cause. This is appropriate when the provider has not yet determined a more specific diagnosis or when the documentation is insufficient for a more precise code.

• Avoid using this code if more specific documentation exists, such as anosmia (R43.0) or ageusia (R43.1).
• Always query the provider for more specific details if the documentation only states "smell/taste disturbance" to allow for more precise coding.
• This code should generally be considered a temporary or placeholder diagnosis until a more definitive cause or type of disturbance is identified.
