Final answer:
When a provider documents a stroke or CVA with no additional information, the default code is I63.9 (Cerebral infarction, unspecified) for ischemic strokes and I61.9 (Intracerebral hemorrhage, unspecified) for hemorrhagic strokes. Additional information should be provided by the provider for more specific coding.
Step-by-step explanation:
When a provider documents a stroke or CVA with no additional information, the default code is I63.9 (Cerebral infarction, unspecified) for ischemic strokes and I61.9 (Intracerebral hemorrhage, unspecified) for hemorrhagic strokes.
However, it is important to note that accurate documentation is crucial in coding strokes. Additional information, such as type (ischemic or hemorrhagic), location, and laterality, should be provided by the provider to assign the most specific code.
