Decision Criteria

clinical Criteria

  • Myocardial infarction occurred more than four weeks ago

documentation Criteria

  • No current symptoms or treatment related to the myocardial infarction

Applicable To

  • Healed myocardial infarction
  • Past myocardial infarction

Excludes

  • Acute myocardial infarction (I21.-)
  • Subsequent myocardial infarction (I22.-)

Clinical Validation Requirements

  • Documentation of myocardial infarction occurring more than four weeks ago
  • No current symptoms or treatment related to the myocardial infarction

Code-Specific Risks

  • Incorrectly coding as acute myocardial infarction
  • Lack of specific timeline documentation

Coding Notes

  • Ensure the documentation specifies the myocardial infarction is old and no longer being actively treated.

Use for a new myocardial infarction occurring within four weeks of a previous one.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting History of Myocardial Infarction to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I25.2.

Impact

Clinical: Inaccurate patient history leading to potential mismanagement., Regulatory: Non-compliance with documentation standards., Financial: Potential for incorrect billing and reimbursement.

Mitigation Strategy

Ensure documentation includes specific dates and current status., Use templates to guide comprehensive documentation.

Impact

Reimbursement: Incorrect DRG assignment leading to potential overpayment., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate patient records and data reporting.

Mitigation Strategy

Use I25.2 for myocardial infarctions older than four weeks without active treatment.

Impact

Using acute myocardial infarction codes for old infarctions.

Mitigation Strategy

Educate coders on the correct use of I25.2 and ensure documentation supports 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.

Cardiology Follow-Up

Specialty: Cardiology

Required Elements

Example Documentation

Patient with 2022 NSTEMI, now asymptomatic. Echo shows EF 55%, no wall motion abnormalities. Continue statin.

Examples: Poor vs. Good Documentation

Poor Documentation Example
MI years ago, doing well.
Good Documentation Example
Healed inferolateral STEMI from 4/2023, EF 60% on echo 1/2025. No angina. Current meds: aspirin 81mg.
