What changes the history of stroke code?
The Alphabetic Index lists these qualifiers under Sequelae, infarction, cerebral. If the record documents one of them, the code changes. Verify the code in the Tabular List before reporting it.

What else changes the history of stroke code?
Z86.73 applies only when the stroke left no neurologic deficit. If a deficit persists — such as aphasia, dysphagia, hemiplegia, ataxia or an abnormal gait — the deficit is coded from category I69 instead, and Z86.73 is not added: the two exclude each other.
“These "late effects" include neurologic deficits that persist after initial onset of conditions classifiable to categories I60-I67.”
“Codes from category I69 should not be assigned if the patient does not have neurologic deficits.”
What does the Tabular List say about Z86.73?
The instructional notes that govern Z86.73, including those it inherits from its category and chapter. An Excludes1 note means the two codes are never reported together.
Excludes1 — never code together
The conditions below can never be reported together with Z86.73 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Inclusion terms
Alternative wording in documentation that is classified to Z86.73.
- Personal history of prolonged reversible ischemic neurological deficit (PRIND)
- Personal history of stroke NOS without residual deficits
Code first — inherited from Z86
The underlying condition below must be sequenced before Z86.73. Z86.73 describes a manifestation and cannot be the principal or first-listed diagnosis.
- any follow-up examination after treatment (Z09)
Excludes2 — not included here — inherited from Z86.7
The conditions below are not part of Z86.73, but a patient may have both at the same time. When documentation supports it, Z86.73 and the excluded code may both be reported.
Code also — inherited from Z77-Z99
Two codes may be needed to describe the condition fully. Whether Z86.73 is sequenced first depends on the reason for the encounter.
- any follow-up examination (Z08-Z09)
Codes, descriptions and Index entries are from the official ICD-10-CM FY2027 release. Guideline text is quoted from the ICD-10-CM Official Guidelines for Coding and Reporting FY 2027. A code must always be verified in the Tabular List before it is reported. Data sources
