Hemangioma of intracranial structuresD18.02

Use for brain hemangiomas not specified as congenital.

Other specified congenital malformations of circulatory systemQ28.3

Use for familial cases confirmed by genetic testing.

Documentation & Coding Risks

Avoid these common issues when documenting Cavernoma.

Failing to document genetic testing for familial cases

Impact

Clinical: Misdiagnosis of familial cavernoma, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials

Mitigation

Always order genetic testing for suspected familial cases, Document results in patient records

Using D18.02 for spinal lesions

Impact

Reimbursement: Incorrect DRG assignment, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data

Mitigation

Use Q06.9 for congenital spinal cavernomas.

Genetic Testing Documentation

Impact

Lack of genetic testing documentation for familial cases.

Mitigation

Ensure all familial cases have documented genetic testing results.
