| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I25.84 | Coronary atherosclerosis due to calcified coronary lesion | Use when calcified lesions are present in coronary arteries, supported by imaging or CAC score. |
|
| I25.83 | Coronary atherosclerosis due to lipid-rich plaque | Use when lipid-rich plaques are present without calcification. |

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 coronary calcification
Decision Criteria
clinical Criteria
- Presence of calcified coronary lesions on imaging
documentation Criteria
- Documentation must explicitly mention calcified lesions
Applicable To
- Calcified coronary artery disease
Excludes
- Lipid-rich plaque (I25.83)
Clinical Validation Requirements
- CAC score ≥100 Agatston units
- CCTA showing calcified plaques
Code-Specific Risks
- Misclassification if calcification is not documented
- Incorrect sequencing with non-coronary atherosclerosis
Coding Notes
- Ensure documentation specifies calcification to support I25.84.
I25.83 - Coronary atherosclerosis due to lipid-rich plaque
Use when lipid-rich plaques are present without calcification.
Applicable To
- Lipid-rich coronary artery disease
Excludes
- Calcified coronary lesion (I25.84)
Clinical Validation Requirements
- IVUS/PET-CT showing lipid core, no calcium
Coding Notes
Ensure lipid-rich plaques are documented without calcification.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Coronary Calcification to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I25.84.
Impact
Clinical: Inadequate clinical assessment, Regulatory: Non-compliance with coding standards, Financial: Potential for denied claims
Mitigation Strategy
Ensure CAC score is included in all relevant documentation, Cross-check imaging reports
Impact
Reimbursement: Incorrect coding may lead to reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use I25.84 when calcification is documented.
Impact
Failure to document calcification can lead to audit flags.
Mitigation Strategy
Ensure all imaging and clinical findings are thoroughly documented.
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.
