| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G31.1 | Senile degeneration of brain, not elsewhere classified | Use when cerebral atrophy is age-related without a specified underlying condition. |
|
| G31.8 | Other specified degenerative diseases of nervous system | Use when cerebral atrophy is due to a specified cause like alcohol use. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for acquired cerebral atrophy
Decision Criteria
clinical Criteria
- MRI shows age-related atrophy without other causes.
coding Criteria
- No other specific degenerative disease identified.
Applicable To
- Age-related cerebral atrophy
Clinical Validation Requirements
- MRI showing regional atrophy patterns
- Absence of other specific underlying conditions
Code-Specific Risks
- Risk of incorrect coding if underlying cause is not properly identified.
Coding Notes
- Ensure documentation specifies the absence of other underlying conditions.
G31.8 - Other specified degenerative diseases of nervous system
Use when cerebral atrophy is due to a specified cause like alcohol use.
Applicable To
- Alcohol-induced cerebral degeneration
Excludes
- Dementia with other diseases classified elsewhere (F02.-)
Clinical Validation Requirements
- Documentation of specific cause such as alcohol use.
Coding Notes
Ensure the specific cause of atrophy is documented and coded.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Acquired Cerebral Atrophy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G31.1.
Impact
Clinical: Inaccurate diagnosis and treatment planning., Regulatory: Potential audit issues., Financial: Incorrect billing and reimbursement.
Mitigation Strategy
Ensure all imaging findings are documented in detail.
Impact
Reimbursement: Incorrect reimbursement due to misclassification., Compliance: Non-compliance with coding guidelines., Data Quality: Poor data quality affecting clinical records.
Mitigation Strategy
Identify and code the specific cause first, such as G31.8 for alcohol-induced.
Impact
Risk of audits due to non-specific coding.
Mitigation Strategy
Ensure documentation supports the specific ICD-10 code used.
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.
