| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| Q06.9 | Congenital malformation of spinal cord, unspecified | Use for congenital spinal cord cavernomas confirmed by imaging. |

| D18.02 | Hemangioma of intracranial structures | Use for sporadic brain cavernomas without familial history. |
|
| Q28.3 | Other specified congenital malformations of circulatory system | Use for familial cerebral cavernomas confirmed by genetic testing. |

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

D18.02 - Hemangioma of intracranial structures
Use for sporadic brain cavernomas without familial history.
Applicable To
- Cavernous hemangioma of brain parenchyma
Excludes
- Familial cerebral cavernous malformation
Clinical Validation Requirements
- MRI showing cavernous hemangioma
- No genetic markers for familial cases
Coding Notes
Ensure no familial history is documented.
Q28.3 - Other specified congenital malformations of circulatory system
Use for familial cerebral cavernomas confirmed by genetic testing.
Applicable To
- Familial cerebral cavernous malformation
Excludes
- Sporadic cavernous hemangioma
Clinical Validation Requirements
- Genetic confirmation of CCM1, CCM2, or CCM3 mutation
Coding Notes
Genetic testing results must be documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

G89.21Differential 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 Cavernoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Q06.9.
Impact
Clinical: Misdiagnosis of familial cavernoma, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Always order genetic testing for suspected familial cases, Document results in patient records
Impact
Reimbursement: Incorrect DRG assignment, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data
Mitigation Strategy
Use Q06.9 for congenital spinal cavernomas.
Impact
Lack of genetic testing documentation for familial cases.
Mitigation Strategy
Ensure all familial cases have documented genetic testing results.
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.
