Short answer · Medically reviewed summary · Last updated: 2026-05-08
The primary ICD-10 code for Cavernous Malformation (specifically of the brain) is D18.02 (Hemangioma of intracranial structures), while the historical ICD-9 code used for this condition was 228.02. These codes are essential for medical billing and clinical documentation, helping healthcare providers track the prevalence of Cavernous Malformation within their systems. Why are medical codes important for Cavernous Malformation? Accurate coding for Cavernous Malformation ensures that patients receive appropriate insurance coverage for diagnostic imaging, such as specialized MRI protocols, and neurosurgical consultations.
ICD10 code of Cavernous Malformation and ICD9 code
ICD-10 and ICD-9 codes for Cavernous Malformation, with classification details for clinicians, coders and patients.
The primary ICD-10 code for Cavernous Malformation (specifically of the brain) is D18.02 (Hemangioma of intracranial structures), while the historical ICD-9 code used for this condition was 228.02. These codes are essential for medical billing and clinical documentation, helping healthcare providers track the prevalence of Cavernous Malformation within their systems.
Why are medical codes important for Cavernous Malformation?
Accurate coding for Cavernous Malformation ensures that patients receive appropriate insurance coverage for diagnostic imaging, such as specialized MRI protocols, and neurosurgical consultations. Because Cavernous Malformation is a vascular lesion rather than a tumor, precise documentation helps clinicians distinguish it from other intracranial pathologies, ensuring that the unique clinical needs of the 124 members within the DiseaseMaps.org community are properly addressed in their medical records.
How is Cavernous Malformation classified?
Clinically, Cavernous Malformation is often categorized based on its location and the presence of genetic triggers. While ICD codes provide a broad administrative classification, researchers and physicians focus on these specific clinical indicators:
- Sporadic form: Occurs as a single lesion without a family history.
- Familial form: Associated with mutations in the CCM1, CCM2, or PDCD10 genes.
- Multiple lesions: Often seen in patients with the hereditary form of Cavernous Malformation.
Is Cavernous Malformation hereditary?
Approximately 20% of individuals with Cavernous Malformation have the familial form, which follows an autosomal dominant inheritance pattern. If you have been diagnosed with familial Cavernous Malformation, genetic counseling is strongly recommended to understand the risks for family members. Understanding whether your specific diagnosis is familial or sporadic is a vital step in your long-term management plan.
Next steps
- Consult with a neurosurgeon or a neurologist specializing in vascular anomalies to review your imaging.
- Request a referral to a genetic counselor if you have a family history of Cavernous Malformation.
- Join the community at DiseaseMaps.org to connect with others who share lived experiences.
- Keep a personal record of your MRI findings and genetic testing reports for your primary care provider.
