CodeDescriptionWhen to UseKey Documentation
I25.10Atherosclerotic heart disease of native coronary artery without angina pectorisUse when there is documented multivessel coronary artery disease without angina symptoms.
  • Coronary angiography showing ≥70% stenosis in multiple vessels
  • Absence of angina symptoms
I25.110Atherosclerotic heart disease of native coronary artery with unstable angina pectorisUse when there is documented multivessel coronary artery disease with unstable angina symptoms.
  • Coronary angiography showing ≥70% stenosis in multiple vessels
  • Presence of unstable angina symptoms

Clinical Decision Support

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

Absence of angina symptoms.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Multivessel Coronary Artery Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I25.10.

Impact

Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials or reduced reimbursement.

Mitigation Strategy

Train staff on the importance of detailed vessel documentation., Implement checklist for angiography reports.

Impact

Reimbursement: Incorrect coding can lead to claim denials., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use I25.702 for atherosclerosis of coronary artery bypass graft.

Impact

Inadequate documentation of specific vessels and stenosis percentages.

Mitigation Strategy

Implement detailed documentation protocols and regular audits.

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.

Use these documentation templates to ensure complete and accurate documentation for Multivessel Coronary Artery Disease. These templates include all required elements for proper coding and billing.

Inpatient Cardiology

Specialty: Cardiology

Required Elements

  • Vessel involvement
  • Stenosis percentage
  • Plaque characteristics
  • Angina symptoms

Example Documentation

Patient presents with 80% stenosis in LAD and 90% in RCA. No angina symptoms reported. Documented as I25.10.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has multivessel disease.
Good Documentation Example
Patient has 80% stenosis in LAD and 90% in RCA, confirmed by angiography. No angina symptoms.
Explanation
The good example provides specific vessel involvement and stenosis details, which are necessary for accurate coding.
