Essential tremor: a unique diagnostic code in ICD-10-CM.

摘要

The International Classification of Diseases-lOth Revision-Clinical Modification (ICD-10-CM) ushers in, for the first time, a specific diagnostic code for essential tremor ("G25.O, essential tremor"). This milestone should not pass without comment. Essential tremor is one of the most prevalent neurological diseases. Although the core diagnostic feature is a kinetic tremor of the arms, other types of tremor (eg, postural, rest, intentional), additional motor features (eg, mild ataxic gait), and non-motor features (especially cognitive difficulties) have also been well described. The disease is associated with progressive functional disability and reduced quality of life. In epidemiological studies, it has been linked with several neurodegenerative diseases, including Parkinson's disease and Alzheimer's disease.
