| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I24.8 | Other forms of acute ischemic heart disease | Use when there is demand ischemia without myocardial infarction and troponin levels are normal. |
|
| I21.A1 | Myocardial infarction type 2 | Use when there is myocardial infarction with elevated troponin levels and evidence of ischemia. |

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

Primary ICD-10-CM Codes for demand ischemia
Decision Criteria
clinical Criteria
- Troponin levels ≤99th percentile
- No evidence of myocardial infarction
Applicable To
- Demand ischemia without myocardial infarction
Excludes
- Myocardial infarction type 2 (I21.A1)
Clinical Validation Requirements
- Troponin levels ≤99th percentile
- Symptoms like chest pain
- Transient EKG changes
Code-Specific Risks
- Confusion with Type 2 MI if troponin levels are not clearly documented.
Coding Notes
- Ensure troponin levels are documented to avoid misclassification.
I21.A1 - Myocardial infarction type 2
Use when there is myocardial infarction with elevated troponin levels and evidence of ischemia.
Applicable To
- Demand ischemia with myocardial infarction
Excludes
- Other forms of acute ischemic heart disease (I24.8)
Clinical Validation Requirements
- Troponin levels >99th percentile
- Evidence of ischemia such as EKG changes or imaging
Coding Notes
Ensure underlying cause is documented and coded first.
Differential Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Demand Ischemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I24.8.
Impact
Clinical: Leads to incorrect diagnosis classification., Regulatory: Non-compliance with coding guidelines., Financial: Potential for incorrect reimbursement.
Mitigation Strategy
Always document troponin levels in the medical record., Ensure EKG changes are noted if present.
Impact
Reimbursement: Incorrect coding can affect DRG assignment and reimbursement., Compliance: Misclassification can lead to compliance issues., Data Quality: Affects quality metrics and registry data.
Mitigation Strategy
Use I21.A1 for Type 2 MI when troponin is elevated and I24.8 when it is not.
Impact
Failure to document troponin levels can lead to audit findings.
Mitigation Strategy
Implement mandatory fields for troponin in EHR templates.
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.
