Official Guidelines for I67.6
FY 2026 ›Sections that reference I67.6
- I.C.9.a.4)Hypertensive Cerebrovascular Disease
For hypertensive cerebrovascular disease, first assign the appropriate code from categories I60-I69, followed by the appropriate hypertension code.
- I.C.9.d.1)Category I69, Sequelae of Cerebrovascular disease
Category I69 is used to indicate conditions classifiable to categories I60- I67 as the causes of sequela (neurologic deficits), themselves classified elsewhere. …
- I.C.9.d.2)Codes from category I69 with codes from I60-I67
Codes from category I69 may be assigned on a health care record with codes from I60-I67, if the patient has a current cerebrovascular disease and deficits from an old cerebrovascular disease.
Sections whose FY 2026 text names I67.6, its I67 category, or a range containing it — the chapter guidance above is the authoritative source.
