Official Coding Guidelines

HTN cerebrovascular disease: code I60-I69 first, then HTN code

For hypertensive cerebrovascular disease, first assign the appropriate code from categories I60-I69, followed by the appropriate hypertension code.

Use I69 for sequelae due to I60-I67 conditions; timing of deficits

Category I69 is used to indicate conditions classifiable to categories I60- I67 as the causes of sequela (neurologic deficits), themselves classified elsewhere. These “late effects” include neurologic deficits that persist after initial onset of conditions classifiable to categories I60-I67. The neurologic deficits caused by cerebrovascular disease may be present from the onset or may arise at any time after the onset of the condition classifiable to categories I60-I67.
