Z95.1 - Presence of aortocoronary bypass graft
Use to indicate the presence of a bypass graft without active disease.
Applicable To
- Status post-CABG
Excludes
- Active coronary artery disease
Clinical Validation Requirements
- Documented history of CABG
- Follow-up imaging showing patent grafts
Coding Notes
Ensure documentation clearly states the presence of the graft.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Coronary Bypass Surgery to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code 02100Z9.
Impact
Clinical: Inaccurate clinical records, Regulatory: Potential audit issues, Financial: Incorrect reimbursement
Mitigation Strategy
Use standardized templates, Cross-check with operative report
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Verify the operative report for the exact number of arteries bypassed.
Impact
Failure to document MCCs can lead to lower DRG assignment.
Mitigation Strategy
Ensure comprehensive documentation of all comorbid conditions.
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.
