Information for Patients

Lewy body disease is one of the most common causes of dementia in the elderly. Dementia is the loss of mental functions severe enough to affect normal activities and relationships. Lewy body disease happens when abnormal structures, called Lewy bodies, build up in areas of the brain. The disease may cause a wide range of symptoms, including

ICD-9 Footnotes

General Equivalence Map Definitions The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set.

Wandering is one of the most dangerous symptoms for patients with dementia. The Alzheimer’s Association reports that six in 10 people (60 percent) with dementia will wander at some point. Be sure to code this behavior if documented in the medical record. Wandering is a warning to caregivers and medical providers that the individual is at high risk for injury and situations that may result in death. Measures that may need to be taken, including additional caregiving staff, relocation to a monitored living setting, etc., depend on documentation in the medical record and proper coding.
