What is the ICD-10 code for mild neurocognitive disorder?

The ICD-10 code for mild neurocognitive disorder without a known cause is G31.84. If due to a known physiological condition, use F06.70 or F06.71 depending on the presence of behavioral disturbances.

How do you code mild neurocognitive disorder with Alzheimer's?

For mild neurocognitive disorder due to Alzheimer's, use G30.9 followed by F06.71 if behavioral disturbances are present.

Code	Description	When to Use	Key Documentation
G31.84	Mild cognitive impairment, so stated	Use when mild cognitive impairment is diagnosed without a known physiological cause.	Neuropsychological testing showing 1-2 SD below norms No evidence of major neurocognitive disorder
F06.70	Mild neurocognitive disorder due to known physiological condition without behavioral disturbance	Use when mild NCD is due to a known physiological condition without behavioral disturbances.	Documentation of underlying condition Neuropsychological testing showing 1-2 SD below norms
F06.71	Mild neurocognitive disorder due to known physiological condition with behavioral disturbance	Use when mild NCD is due to a known physiological condition with behavioral disturbances.	Documentation of underlying condition Behavioral disturbances documented

Documentation & Coding Risks

Avoid these common issues when documenting Mild Neurocognitive Disorder.

Using G31.84 for patients with known physiological causes

Impact

Clinical: Misrepresentation of patient's condition, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials

Mitigation

Verify if a physiological cause is documented, Use F06.70 or F06.71 as appropriate

Using G31.84 when a physiological cause is known

Impact

Reimbursement: Potential denial of claims due to incorrect coding, Compliance: Non-compliance with ICD-10 coding guidelines, Data Quality: Inaccurate clinical data affecting patient records

Mitigation

Use F06.70 or F06.71 depending on the presence of behavioral disturbances.

Failing to document behavioral disturbances for F06.71

Impact

Reimbursement: Reduced reimbursement due to incorrect DRG assignment, Compliance: Risk of audit failure, Data Quality: Incomplete clinical data

Mitigation

Ensure all behavioral symptoms are documented in the patient's record.

Behavioral Disturbance Documentation

Impact

Failure to document behavioral disturbances when coding F06.71

Mitigation

Implement thorough behavioral assessments and documentation protocols.
