| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| Z86.73 | Personal history of TIA and cerebral infarction without residual deficits | Use when a patient has a documented history of stroke or TIA with no current deficits. |
|
| I69.3- | Sequelae of cerebrovascular disease | Use when there are residual deficits from a previous stroke. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about History of Stroke
Primary ICD-10-CM Codes for history of stroke
Decision Criteria
clinical Criteria
- Patient has a history of stroke with no current deficits.
documentation Criteria
- Provider notes 'history of stroke without residual deficits'.
Applicable To
- History of resolved stroke
- History of TIA without residuals
Clinical Validation Requirements
- Imaging reports confirming past stroke
- Neurological exam showing no deficits
Code-Specific Risks
- Incorrectly coding as acute stroke
- Using without proper documentation of no residuals
Coding Notes
- Ensure documentation explicitly states 'no residual deficits' for accurate coding.
I69.3- - Sequelae of cerebrovascular disease
Use when there are residual deficits from a previous stroke.
Applicable To
- Residual hemiplegia
- Residual aphasia
Excludes
- Acute stroke (I63.-)
- History without residuals (Z86.73)
Clinical Validation Requirements
- Neurological exam showing residual deficits
- Linkage to past stroke event
Coding Notes
Ensure deficits are clearly documented and linked to the past stroke.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Family history of stroke
Z82.3Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting History of Stroke to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z86.73.
Impact
Clinical: Potential mismanagement of patient care., Regulatory: Increased risk of audit failures., Financial: Incorrect billing and potential denials.
Mitigation Strategy
Use specific terms like 'resolved' or 'no residual deficits'., Ensure imaging reports are referenced.
Impact
Reimbursement: Incorrect DRG assignment leading to lower reimbursement., Compliance: Potential for audit failures and compliance issues., Data Quality: Misrepresentation of patient history in medical records.
Mitigation Strategy
Use Z86.73 for history without residuals, not I63.-
Impact
Using I63.- instead of Z86.73 for history without residuals.
Mitigation Strategy
Educate providers on proper documentation and code selection.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
