CODES
ICD10
R43.2 Parageusia
ICD9
781.1 Disturbances of sensation of smell and taste
SNOMED
- Loss of taste (finding)
- Loss of taste anterior two thirds of tongue (finding)
- Loss of taste posterior one third of tongue (finding)
CLINICAL PEARLS
- Ageusia is the absence of the sense of taste.
- To treat the symptoms of ageusia and hypogeusia, the underlying cause must first be identified and treated. Disorders of smell contribute greatly to disorders of taste.
- There are several new diagnostic modalities for detecting taste disorders; however, most are only useful in the laboratory setting.
- The main treatment for ageusia is addressing the underlying cause.
