I25.83-I25.84Primary Range
Coronary atherosclerosis due to lipid-rich plaque or calcified coronary lesion
These codes are used to specify the type of plaque present in non-obstructive coronary artery disease.
Angina and acute ischemic heart diseases
These codes are relevant when non-obstructive CAD is associated with angina or acute ischemic events.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.84 | Coronary atherosclerosis due to calcified coronary lesion | Use when coronary CT angiography confirms calcified lesions in coronary arteries. |
|
| I25.83 | Coronary atherosclerosis due to lipid rich plaque | Use when coronary CT angiography confirms lipid-rich plaques in coronary arteries. |

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

Decision Criteria
clinical Criteria
- Presence of calcified lesions on imaging
documentation Criteria
- Detailed imaging report confirming calcified lesions
Applicable To
- Calcified coronary lesions
Excludes
- Atherosclerosis of native coronary artery without angina pectoris (I25.10)
Clinical Validation Requirements
- Coronary CT angiography showing calcified lesions
- CAD-RADS reporting with calcified plaque
Code-Specific Risks
- Incorrectly coding as lipid-rich plaque
Coding Notes
- Ensure documentation specifies calcified lesions to use this code.
I25.83 - Coronary atherosclerosis due to lipid rich plaque
Use when coronary CT angiography confirms lipid-rich plaques in coronary arteries.
Applicable To
- Lipid-rich coronary plaques
Excludes
- Atherosclerosis of native coronary artery without angina pectoris (I25.10)
Clinical Validation Requirements
- Coronary CT angiography showing lipid-rich plaques
- CAD-RADS reporting with lipid-rich plaque
Coding Notes
Ensure documentation specifies lipid-rich plaques to use this code.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Non-Obstructive Coronary Artery Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I25.84.
Impact
Clinical: Leads to inaccurate diagnosis coding, Regulatory: Non-compliance with coding standards, Financial: Potential for incorrect reimbursement
Mitigation Strategy
Ensure imaging reports are reviewed and documented, Train staff on the importance of detailed documentation
Impact
Reimbursement: May lead to DRG downgrades, Compliance: Non-compliance with coding guidelines, Data Quality: Reduces specificity and accuracy of health records
Mitigation Strategy
Ensure documentation specifies plaque type to select the correct code.
Impact
High risk of audits if unspecified codes are used when specific codes are applicable.
Mitigation Strategy
Ensure all documentation includes specific plaque characterization.
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.
