Lewy body dementia is the second-most common type of progressive dementia after Alzheimer's disease, and it is captured with ICD-10-CM code G31. 83, Dementia with Lewy Bodies.
Lewy body dementia (LBD) is a broad term covering two separate neurological disorders: dementia with Lewy bodies and Parkinson's disease dementia. The same biological changes to the brain cause both disorders. A buildup of Lewy bodies (proteins called alpha-synucleins) causes LBD.
noun. : an eosinophilic inclusion body found in the cytoplasm of neurons of the cortex and brain stem in Parkinson's disease, Lewy body disease, and other neurodegenerative disorders.
For hospital discharge abstracts data, use the ICD-9-CM codes: 291.1x, 291.2x and 292.82 to define dementia.
Lewy body dementia (LBD) is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain whose changes, in turn, can lead to problems with thinking, movement, behavior, and mood.
A few factors seem to increase the risk of developing Lewy body dementia, including:Age. People older than 60 are at greater risk.Sex. Lewy body dementia affects more men than women.Family history. Those who have a family member with Lewy body dementia or Parkinson's disease are at greater risk.
Dementia is a loss of mental functions that is severe enough to affect your daily life. The main difference between the two is when the start of thinking and movement symptoms occur. Dementia with Lewy bodies first causes problems with mental functioning similar to Alzheimer's disease.
Clinicians and researchers use the "one-year rule" to help make a diagnosis. If cognitive symptoms appear at the same time as or at least a year before movement problems, the diagnosis is dementia with Lewy bodies.
The biggest difference between Parkinson's disease dementia and dementia with Lewy bodies is the order of onset of the symptoms. Clinicians usually distinguish between these by asking which set of symptoms (body or brain) appeared first.
Dementia in other diseases classified elsewhere without behavioral disturbance. F02. 80 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM F02.
ICD-10-CM combines the disease with the behavior. To code vascular dementia without behavioral disturbance, use only the combination code F01. 50 Vascular dementia without behavioral disturbance. For vascular dementia with behavioral disturbance, use only the combination code F01.
ICD-Code I10 is a billable ICD-10 code used for healthcare diagnosis reimbursement of Essential (Primary) Hypertension.
Neuropathy, ataxia, and retinitis pigmentosa, also known as NARP syndrome, is a rare disease with mitochondrial inheritance that causes a variety of signs and symptoms chiefly affecting the nervous system.
Inclusion Terms are a list of concepts for which a specific code is used. The list of Inclusion Terms is useful for determining the correct code in some cases, but the list is not necessarily exhaustive.

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 331.82 was previously used, G31.83 is the appropriate modern ICD10 code.
G31.83 is a valid billable ICD-10 diagnosis code for Dementia with Lewy bodies . It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021 .
DO NOT include the decimal point when electronically filing claims as it may be rejected. Some clearinghouses may remove it for you but to avoid having a rejected claim due to an invalid ICD-10 code, do not include the decimal point when submitting claims electronically.
Lewy body dementia is the second-most common type of progressive dementia after Alzheimer’s disease, and it is captured with ICD-10-CM code G31.83, Dementia with Lewy Bodies. G31.83 is listed in section G31, titled "Other degenerative diseases of nervous system, not elsewhere classified,” and is included in category G31.8, titled "Other specified degenerative diseases of nervous system."
In addition to Lewy body dementia, the code G31.83 also identifies the following: 1 Dementia with Parkinsonism and Lewy body disease. As far as the MS-DRG assignment, under version 33.0, code G31.83 groups to a two-tiered MS-DRG 2 MS-DRG 056: Degenerative nervous system disorders with MCC, or 3 MS-DRG 057: Degenerative nervous system disorders without MCC
Type 2 exclusions indicate that the conditions excluded are not part of the condition represented by the code, but the patient may have both conditions at the same time. Coders need to be sure to review section G31's exclusions before assigning this code for reimbursement purposes.
Senile dementia of the Lewy body type. Lewy body dem entia can also be abbreviated as LBD if this is an approved abbreviation for your facility, otherwise the physician must clarify this abbreviation.
G31.83 is not a CC or MCC, but the presence of the disease can increase nursing care and/or the patient’s length of stay, and therefore it is very important to capture it as a secondary diagnosis to substantiate the resources the patient consumed.
Other documented descriptive synonyms for Lewy body dementia are: Diffuse Lewy body disease. Lewy body dementia with or without behavioral disturbance. Senile dementia of the Lewy body type.
A progressive, neurodegenerative disease characterized by loss of function and death of nerve cells in several areas of the brain leading to loss of cognitive function such as memory and language. Alzheimer's disease (ad) is the most common form of dementia among older people.
A brain disorder that usually starts in late middle age or old age and gets worse over time. Symptoms include loss of memory, confusion, difficulty thinking, and changes in language, behavior, and personality.
A disabling degenerative disease of the nervous system occurring in middle-aged or older persons and characterized by dementia and failure of memory for recent events, followed by total incapacitation and death. Types of the alzheimer syndrome are differentiated by the age of onset and genetic characteristics.
There are two more codes that deserve attention. The first code is for delirium due to a known physiological condition, F05 De lirium due to known physiological condition. Although individuals with dementia may have delusions or hallucinations, delirium is frequently due to infection (often, a urinary tract infection), medication mismanagement, etc. It should not be considered a symptom of dementia unless the provider documents it as such.#N#The second code is for wandering, Z91.83 Wandering in diseases classified elsewhere. 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.
To code vascular dementia without behavioral disturbance, use only the combination code F01.50 Vascular dementia without behavioral disturbance. For vascular dementia with behavioral disturbance, use only the combination code F01.51 Vascular dementia with behavioral disturbance.
Frontotemporal Dementia. Frontotemporal dementia occurs from damage to the area of the brain behind the forehead. Behavioral disturbances are often coded with this condition because one of the jobs of the frontal lobe is to filter words and actions so they are socially acceptable.
This is the second most frequent cause of dementia behind Alzheimer’s disease . ICD-10-CM combines the disease with the behavior.
ICD-10-CM provides codes for memory loss without a dementia, as well. First, know that a certain amount of memory loss is a normal part of aging and is not a disease process. This is determined by whether the memory loss is about equal to people of the same age, or if it is significantly more.#N#For those who share about the same amount of forgetfulness as everyone else their age, use R41.81 Age-related cognitive decline. For patients experiencing more decline than is expected for their age, and if the provider specifically documents “mild cognitive dementia,” use G31.84 Mild cognitive impairment, so stated. This diagnosis carries a lot of emotional weight and potential impact to a patient’s life decisions. If you have doubt about the correct code, query the provider.
To code diagnosed Parkinson’s disease with dementia, use G20 Parkinson’s disease. Also use a secondary code for “without behavioral disturbance” (F02.80) or “with behavioral disturbance” (F02.81). Query the provider if the documentation is not clear enough for you to make a determination.
Alzheimer’s Disease. Many people who suffer from Alzheimer’s disease may experience phases of agitation, aggression, combativeness, etc. These symptoms dramatically influence the level of care needed to keep the individual safe, so it’s very important to code this information if it is included in the documentation.
