R70-R79Primary Range
Abnormal findings on examination of blood, without diagnosis
This range includes codes for abnormal blood chemistry findings, including elevated troponin levels without myocardial infarction.
Ischemic heart diseases
This range includes myocardial infarction codes, relevant when troponin elevation is due to ischemic heart disease.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R79.89 | Other specified abnormal findings of blood chemistry | Use when troponin is elevated without evidence of myocardial infarction. |
|
| I21.A1 | Myocardial infarction type 2 | Use when troponin elevation is due to demand ischemia, such as in sepsis or tachyarrhythmia. |

Decision Criteria
clinical Criteria
- Troponin elevation without ischemic symptoms
documentation Criteria
- Clear documentation of non-ischemic cause
Applicable To
- Elevated troponin without myocardial infarction
Excludes
- Myocardial infarction (I21.-)
Clinical Validation Requirements
- Troponin level above the 99th percentile
- Absence of ischemic symptoms or EKG changes
Code-Specific Risks
- Misclassification if ischemic symptoms are present
Coding Notes
- Ensure documentation clearly states the absence of myocardial infarction.
I21.A1 - Myocardial infarction type 2
Use when troponin elevation is due to demand ischemia, such as in sepsis or tachyarrhythmia.
Applicable To
- Type 2 myocardial infarction due to demand ischemia
Excludes
- Type 1 myocardial infarction (I21.0-I21.4)
Clinical Validation Requirements
- Troponin rise/fall pattern
- Ischemic symptoms without coronary thrombosis
Coding Notes
Ensure documentation specifies Type 2 MI and underlying cause.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential 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 Troponin Elevation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R79.89.
Impact
Clinical: Potential misdiagnosis of myocardial infarction, Regulatory: Non-compliance with documentation standards, Financial: Incorrect billing and reimbursement
Mitigation Strategy
Educate providers on documentation specificity, Use templates for consistent documentation
Impact
Reimbursement: Incorrect DRG assignment, Compliance: Non-compliance with ICD-10 guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Use R79.89 for elevated troponin without MI.
Impact
Risk of incorrect coding for elevated troponin without MI
Mitigation Strategy
Regular training on updated coding guidelines
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.
