Other disturbances of smell and taste

This code signifies various unspecified or less common disorders affecting a patient's sense of smell (olfaction) or taste (gustation). It encompasses conditions where the specific type of disturbance, such as anosmia or ageusia, is not documented or when the disturbance is atypical.

Use this code when documentation indicates a patient is experiencing a disturbance of smell or taste that is not specifically defined as anosmia, hyposmia, parosmia, ageusia, or dysgeusia. This applies to scenarios where the provider notes "smell disturbance," "taste alteration," or "other chemosensory dysfunction" without further specificity.

• Do not use this code if a more specific disturbance of smell (e.g., anosmia, hyposmia) or taste (e.g., ageusia, dysgeusia) is documented.
• Always review the medical record for any underlying cause or associated conditions that may require additional coding.
• Ensure the documentation clearly states a disturbance of smell or taste, even if not fully characterized, to support the use of this code.
