I67.6
BillableNonpyogenic thrombosis of intracranial venous system
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A blood clot that forms in the veins inside the brain without being caused by infection. This condition can restrict blood flow in the brain and may lead to serious complications like stroke or increased pressure inside the skull.
Coding Tips
- •Verify documentation specifies the thrombosis is nonpyogenic (non-infectious) to distinguish from infectious causes, which would be coded differently
- •Consider if additional codes are needed for laterality (right vs. left) or specific venous location (sagittal sinus, transverse sinus, etc.) if the documentation provides this detail
