ICD-10 (International Classification of Diseases, 10th Revision) is a medical classification system used by coders to classify and code diseases and conditions. Here is a guide to coding dementia using ICD-10 codes:
- Alzheimer’s disease: G30
- Alzheimer’s disease is the most common cause of dementia
- Code G30 is used to identify cases of Alzheimer’s disease
- Vascular dementia: F01.5
- Vascular dementia is caused by reduced blood flow to the brain
- Code F01.5 is used to identify cases of vascular dementia
- Lewy body dementia: G31.83
- Lewy body dementia is characterized by abnormal protein deposits in the brain
- Code G31.83 is used to identify cases of Lewy body dementia
- Frontotemporal dementia: G31.0
- Frontotemporal dementia is caused by damage to the frontal and/or temporal lobes of the brain
- Code G31.0 is used to identify cases of frontotemporal dementia
- Mixed dementia: F01.8
- Mixed dementia refers to cases where multiple types of dementia are present
- Code F01.8 is used to identify cases of mixed dementia
It is important for coders to accurately code the type of dementia present in a patient, as this can impact treatment and care planning. It is also important to note that ICD-10 codes are regularly updated, so it is important for coders to stay up-to-date on any changes.
