Often a patient with confirmed occlusion of his precerebral and cerebral arteries may have signs and symptoms of a cerebral infarction but it is not possible to determine the vessel responsible for the infarction. Because of this, use of the 5th digits for categories 433, Occlusion and stenosis of precerebral arteries, and 434, Occlusion of cerebral arteries, has been a problem. A 5th digit modifies the code to which it is assigned. 5th digit 1, with cerebral infarction, modifies codes that specify a vessel. If it can't be determined that the site of an occlusion is also the site responsible for the infarct then its is incorrect to use 5th digit 1. It is also a problem using 5th digit 0, without mention of infarction, since the patient clearly has had an infarct and it is documented as such. The use of code 436, Acute, but ill-defined, cerebrovascular disease, is always discouraged, and is illogical with a code that has a 5th digit stating without infarct.

A solution to this problem is being proposed. A new 5th digit for "with cerebral infarction of other or unspecified vessel" would be added to the 5th digit subclassifications for categories 433 and 434. The existing 5th digit 1 would be retitled to read "with cerebral infarction of this vessel. With this modification the use of a 5th digit indicating a cerebral infarction could still be used even when the site of the infarct is unknown.
