Lewy Body Dementia ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Lewy Body Dementia?

Lewy Body Dementia (LBD) is a neurodegenerative disorder marked by complex symptoms and the presence of Lewy bodies in the brain. The ICD-10 codes for LBD are critical for accurate documentation, diagnosis, and billing. Here are the key codes and their clinical descriptions:

• G31.83 - Dementia with Lewy bodies: This code is specific to LBD, characterized by fluctuating cognition, visual hallucinations, and parkinsonian motor symptoms.
• F02.80 - Dementia in other diseases classified elsewhere without behavioral disturbance: Utilized when LBD is diagnosed in the context of another medical condition, without behavioral disturbances.
• F02.81 - Dementia in other diseases classified elsewhere with behavioral disturbance: This code is used when LBD is associated with another medical condition and is accompanied by behavioral disturbances such as aggression or agitation.
• G20 - Parkinson's disease: Although primarily for Parkinson's, this code may be relevant for LBD patients, as they often exhibit Parkinsonian features.
• F01.50 - Vascular dementia without behavioral disturbance: If LBD is accompanied by cerebrovascular disease without behavioral symptoms, this code may be appropriate.
• F01.51 - Vascular dementia with behavioral disturbance: Indicates vascular dementia with behavioral disturbances, which can occur in LBD patients.
• F03.90 - Unspecified dementia without behavioral disturbance: This non-specific code may be used when dementia is present without further specification or behavioral disturbances.
• F03.91 - Unspecified dementia with behavioral disturbance: Used for cases of dementia where the type is unspecified, but there are behavioral disturbances.

For detailed guidance on applying these codes in clinical practice, please refer to our explainer video on Lewy Body Dementia ICD Codes. Ensure accurate coding by cross-referencing the patient's clinical presentation with the appropriate ICD-10 codes

Clinical Information

Lewy Body Dementia is a complex, multifaceted condition:

• Pathophysiology: Characterized by the presence of Lewy bodies, abnormal protein aggregates in the brain's cortex.
• Symptoms: Patients may exhibit cognitive impairment, fluctuations in attention, parkinsonian movement disorders, and visual hallucinations.
• Progression: LBD is typically progressive and can lead to significant disability.
• Diagnosis: Diagnosis is clinical, often supported by imaging and excluding other causes of dementia.
• Management: Treatment is symptomatic, focusing on improving quality of life, and may include pharmacological and non-pharmacological interventions.

Synonyms Include:

• Dementia with Lewy bodies
• Diffuse Lewy body disease
• Cortical Lewy body disease
• Lewy body variant of Alzheimer's disease
• Parkinson's disease dementia
