What is the ICD-10 code for non-obstructive coronary artery disease?

The ICD-10 codes for non-obstructive coronary artery disease are I25.83 for lipid-rich plaque and I25.84 for calcified lesions.

How do you code non-obstructive CAD with angina?

For non-obstructive CAD with angina, use I25.83 or I25.84 depending on plaque type, and add I20.8 for angina.

Documentation & Coding Risks

Avoid these common issues when documenting Non-Obstructive Coronary Artery Disease.

Failing to document plaque type

Impact

Clinical: Leads to inaccurate diagnosis coding, Regulatory: Non-compliance with coding standards, Financial: Potential for incorrect reimbursement

Mitigation

Ensure imaging reports are reviewed and documented, Train staff on the importance of detailed documentation

Using unspecified codes when more specific ones are available

Impact

Reimbursement: May lead to DRG downgrades, Compliance: Non-compliance with coding guidelines, Data Quality: Reduces specificity and accuracy of health records

Mitigation

Ensure documentation specifies plaque type to select the correct code.

Use of unspecified codes

Impact

High risk of audits if unspecified codes are used when specific codes are applicable.

Mitigation

Ensure all documentation includes specific plaque characterization.
