Primary ICD-10-CM Codes for mild neurocognitive disorder
Decision Criteria
clinical Criteria
- No known physiological cause identified
coding Criteria
- No major neurocognitive disorder present

- Mild cognitive impairment without known cause
Excludes
- Major neurocognitive disorder
- Mild NCD due to known physiological condition
Clinical Validation Requirements
- Neuropsychological testing showing 1-2 SD below norms
- No evidence of major neurocognitive disorder
Code-Specific Risks
- Misclassification if underlying cause is identified later
Coding Notes
- Ensure no underlying cause is documented before using this code.
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.
Applicable To
- Mild NCD due to conditions like TBI, HIV without behavioral issues
Excludes
- Mild NCD with behavioral disturbances
Clinical Validation Requirements
- Documentation of underlying condition
- Neuropsychological testing showing 1-2 SD below norms
Coding Notes
Ensure documentation clearly states absence of behavioral disturbances.
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.
Applicable To
- Mild NCD due to conditions like Alzheimer's with behavioral issues
Excludes
- Mild NCD without behavioral disturbances
Clinical Validation Requirements
- Documentation of underlying condition
- Behavioral disturbances documented
Coding Notes
Ensure behavioral disturbances are well-documented.
Ancillary Codes

F06.71Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Mild Neurocognitive Disorder to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G31.84.
Impact
Clinical: Misrepresentation of patient's condition, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Verify if a physiological cause is documented, Use F06.70 or F06.71 as appropriate
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 Strategy
Use F06.70 or F06.71 depending on the presence of behavioral disturbances.
Impact
Reimbursement: Reduced reimbursement due to incorrect DRG assignment, Compliance: Risk of audit failure, Data Quality: Incomplete clinical data
Mitigation Strategy
Ensure all behavioral symptoms are documented in the patient's record.
Impact
Failure to document behavioral disturbances when coding F06.71
Mitigation Strategy
Implement thorough behavioral assessments and documentation protocols.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
