What This Code Means
I69.318 is the ICD-10-CM diagnosis code for other symptoms and signs involving cognitive functions following cerebral infarction. Other cognitive problems or symptoms not specifically listed that result from a previous stroke. I69.318 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering cerebrovascular diseases (i60-i69).
I69.318 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code only when the cognitive deficit does not fit into the more specific categories (I69.311-I69.315).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for I69.318 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
