Dysgeusia, also known as parageusia, is a distortion of the sense of taste. Dysgeusia is also often associated with ageusia, which is the complete lack of taste, and hypogeusia, which is a decrease in taste sensitivity. [1] An alteration in taste or smell may be a secondary process in various disease states, or it may be the primary symptom.
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Patients with ageusia observed in 28.0% of patients, hypogeusia in about 33.5%, and dysgeusia in about 41.3% of patients. [10] In April 2020, 88% of a series of over 400 COVID-19 disease patients in Europe were reported to report gustatory dysfunction (86% reported olfactory dysfunction). [11]
Under the proposal, the ICD-9-CM code sets would be replaced with the ICD-10-CM code sets, effective October 1, 2013. On April 17, 2012, the Department of Health and Human Services (HHS) published a proposed rule that would delay the compliance date for the ICD-10-CM and PCS by 12 months-from October 1, 2013, to October 1, 2014.

Adoption of ICD-10-CM was slow in the United States. Since 1979, the US had required ICD-9-CM codes [11] for Medicare and Medicaid claims, and most of the rest of the American medical industry followed suit. On 1 January 1999 the ICD-10 (without clinical extensions) was adopted for reporting mortality, but ICD-9-CM was still used for morbidity ...
While zinc supplementation may treat certain taste dysfunctions, there is a lack of evidence for treatment regarding hypogeusia and dysgeusia not caused by low zinc concentrations in the body. [6] While the mechanisms surrounding hypogeusia from PD are hypothesized, specific treatments are not researched enough. [3]
Dysgeusia (usually a bitter or metallic taste) is present in about 60% of people with BMS, a factor which led to the concept of a defect in sensory peripheral neural mechanisms. [12] Changes in the oral environment, such as changes in the composition of saliva, may induce neuropathy or interruption of nerve transduction.
Degrees of vision loss vary dramatically, although the ICD-9 released in 1979 categorized them into three tiers: normal vision, low vision, and blindness.Two significant causes of vision loss due to sensory failures include media opacity and optic nerve diseases, although hypoxia and retinal disease can also lead to blindness.
