Nontraumatic intracerebral hemorrhage
In Cerebrovascular diseases (I60-I69), chapter 9: Diseases of the Circulatory System
9 billable codes under I61: all are an MCC; all map to HCC 248 (Intracranial Hemorrhage).A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

About the condition

Hemorrhagic Stroke
A stroke happens when there is a loss of blood flow to part of the brain. Your brain cells cannot get the oxygen and nutrients they need from blood, and they start to die within a few minutes. This can cause lasting brain damage, long-term disability, or even death.
