| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I21.29 | ST elevation (STEMI) myocardial infarction involving other coronary artery (septal branch) | Use when there is a confirmed STEMI involving the septal branch of the LAD. |
|
| I21.4 | Non-ST elevation (NSTEMI) myocardial infarction | Use when there is a confirmed NSTEMI involving the septal region. |

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 septal infarct
Decision Criteria
clinical Criteria
- ST elevation in V1-V2 with septal branch occlusion
Applicable To
- Isolated septal STEMI
Excludes
- NSTEMI (I21.4)
Clinical Validation Requirements
- ST elevation in leads V1-V2
- Angiography showing septal branch occlusion
Code-Specific Risks
- Incorrectly coding as unspecified MI if septal involvement is documented.
Coding Notes
- Ensure documentation specifies 'septal' and the involved artery.
I21.4 - Non-ST elevation (NSTEMI) myocardial infarction
Use when there is a confirmed NSTEMI involving the septal region.
Applicable To
- Septal NSTEMI
Excludes
- STEMI (I21.29)
Clinical Validation Requirements
- Troponin elevation without ST elevation in contiguous leads
Coding Notes
Document troponin levels and absence of ST elevation.
Ancillary Codes

I23.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Septal Infarct to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I21.29.
Impact
Clinical: Leads to misclassification of the MI type., Regulatory: Non-compliance with ICD-10 coding guidelines., Financial: Potential loss in reimbursement due to incorrect DRG assignment.
Mitigation Strategy
Educate providers on the importance of detailed documentation., Use templates to guide documentation.
Impact
Reimbursement: Incorrect coding may lead to lower reimbursement., Compliance: May result in non-compliance with coding standards., Data Quality: Impacts the accuracy of clinical data records.
Mitigation Strategy
Use I21.29 when septal involvement is specified.
Impact
Risk of audits due to unspecified MI coding.
Mitigation Strategy
Ensure detailed documentation of MI site and type.
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.
