Parageusia

This code represents a disorder characterized by a distorted sense of taste, where substances taste different from what they normally would. Patients may perceive a persistent unpleasant or altered taste, such as metallic, bitter, or foul, even when no such taste is present. This condition can significantly impact appetite and quality of life.

Use this code when documentation clearly indicates a patient is experiencing parageusia, also known as dysgeusia or taste distortion. This typically occurs when a patient complains of an altered or unpleasant taste sensation that is not consistent with the food or drink consumed. Supporting documentation should include patient complaints, physician assessment, and any identified causes if known.

• Differentiate from ageusia (absence of taste) or hypogeusia (reduced taste sensitivity), which have distinct codes.
• Always look for an underlying cause if documented, such as medication side effects, neurological conditions, or oral infections, and code it as a secondary diagnosis.
• Ensure the documentation specifies "distorted" or "altered" taste rather than simply "loss" or "reduction" of taste.
