| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| 021009Z | Bypass of one coronary artery using autologous arterial tissue, open approach | Use when a single coronary artery is bypassed using an autologous arterial graft via an open approach. |
|
| 02RF08Z | Replacement of aortic valve with synthetic substitute, open approach | Use for open surgical replacement of the aortic valve with a mechanical prosthesis. |

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

02RF08Z - Replacement of aortic valve with synthetic substitute, open approach
Use for open surgical replacement of the aortic valve with a mechanical prosthesis.
Applicable To
- AVR with mechanical prosthesis
Excludes
- Transcatheter aortic valve replacement (TAVR)
Clinical Validation Requirements
- Aortic stenosis with gradient >40mmHg
- Symptomatic congestive heart failure
Coding Notes
Ensure documentation includes valve type, size, and surgical approach.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Open Heart Surgery to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code 021009Z.
Impact
Clinical: Inaccurate clinical records affecting patient care., Regulatory: Potential for audit discrepancies., Financial: Incorrect DRG assignment leading to reimbursement issues.
Mitigation Strategy
Use detailed templates for operative notes., Conduct regular documentation audits.
Impact
Clinical: Misleading clinical records., Regulatory: Non-compliance with documentation standards., Financial: Incorrect billing and potential revenue loss.
Mitigation Strategy
Implement checklist for operative documentation., Train staff on documentation requirements.
Impact
Reimbursement: Incorrect coding can lead to underpayment or overpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Verify the operative report for the exact number of arteries bypassed and use separate codes for different graft sources.
Impact
Reimbursement: May affect DRG assignment and reimbursement., Compliance: Potential for audit issues due to incomplete documentation., Data Quality: Inaccurate representation of surgical procedure in medical records.
Mitigation Strategy
Ensure the operative note specifies whether a mechanical or tissue valve was used, including size and type.
Impact
Inadequate documentation of graft sources and anastomosis sites.
Mitigation Strategy
Use standardized templates and conduct regular audits.
Impact
Failure to specify valve type and size.
Mitigation Strategy
Implement documentation checklists and training.
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.
