Primary ICD-10-CM Code for procedure system

Bypass Coronary Artery, One Artery from Left Internal Mammary, Open Approach
Non-billable Code

Decision Criteria

clinical Criteria

  • Presence of coronary artery disease requiring surgical intervention

documentation Criteria

  • Operative note detailing the bypass procedure

Applicable To

  • Coronary artery bypass graft (CABG)

Excludes

  • Percutaneous coronary intervention

Clinical Validation Requirements

  • Operative report specifying bypass from LIMA to LAD
  • Intraoperative imaging confirming graft patency

Code-Specific Risks

  • Incorrect specification of the artery bypassed
  • Omission of the approach used

Coding Notes

  • Ensure documentation specifies the artery bypassed and the approach used.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Insertion of Intraluminal Device into Coronary Artery, Open Approach

0JH606Z
Use when a device is inserted during the bypass procedure.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Dilation of Coronary Artery, One Artery, Percutaneous Approach

02703ZZ
Used for percutaneous coronary interventions, not open surgical bypass.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting ICD-10-PCS Procedure Coding System to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code 021009Z.

Impact

Clinical: Leads to vague clinical records., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to lack of specificity.

Mitigation Strategy

Train staff on the importance of detailed documentation.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.

Mitigation Strategy

Always specify the side (right, left, or bilateral) in the documentation.

Impact

Risk of incorrect coding due to lack of specificity in documentation.

Mitigation Strategy

Implement regular training and audits.

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.
