| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C71.0 | Malignant neoplasm of cerebrum, except lobes and ventricles | Use when glioblastoma is confirmed in the frontal lobe. |
|
| C71.9 | Malignant neoplasm of brain, unspecified | Use when glioblastoma is confirmed but the specific location is not documented. |

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

C71.9 - Malignant neoplasm of brain, unspecified
Use when glioblastoma is confirmed but the specific location is not documented.
Applicable To
- Glioblastoma, unspecified location
Excludes
- Benign neoplasm of brain (D33.0)
Clinical Validation Requirements
- Histopathological confirmation of glioblastoma
- IDH-wildtype status confirmation
Coding Notes
Ensure molecular marker status is documented if available.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Glioblastoma Multiforme to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C71.0.
Impact
Clinical: May affect treatment decisions and outcomes., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims due to incomplete documentation.
Mitigation Strategy
Ensure all molecular tests are documented., Review documentation for completeness before coding.
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement issues., Compliance: Non-compliance with coding guidelines requiring molecular marker documentation., Data Quality: Inaccurate data for clinical research and treatment outcomes.
Mitigation Strategy
Ensure IDH status is documented and coded appropriately.
Impact
Failure to document molecular markers can lead to audit findings.
Mitigation Strategy
Implement a checklist for molecular marker documentation in glioblastoma cases.
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.
