Assign code G81. 94, Hemiplegia, unspecified affecting left nondominant side, as an additional diagnosis. When unilateral weakness is clearly documented as being associated with a stroke, it is considered synonymous with hemiparesis/hemiplegia.

When should you code history of stroke?

5. History of Stroke (ICD-10 code Z86. 73) should be used when the patient is being seen in an out patient setting subsequent to an inpatient stay. In addition, this code should be used when the patient does not exhibit neurologic deficits due to cerebrovascular disease (i.e., no late effects due to stroke).

When do you code acute stroke?

Acute stroke codes are only appropriate during the acute event, such as in the doctor's office when the patient is experiencing acute right-sided weakness with aphasia, for which an ambulance is summoned, or during the inpatient admission for the acute CVA.
