Coronary Artery Bypass Graft Coding in ICD-10-PCS

Description

Coronary Artery Bypass Graft Coding in ICD-10-PCS is an online, self-paced course for inpatient coders who need a clear understanding of how CABG procedures are performed and classified in ICD-10-PCS. This course reviews common graft types—including LIMA, RIMA, and aortocoronary grafts—along with related procedures performed during bypass surgery. Coders will learn how to analyze CABG operative notes, apply official coding guidelines, and understand coronary artery anatomy such as the RCA and LMCA to support accurate code selection. The course also addresses newer technologies, including VEST™ Venous External Support, and incorporates real-world examples and Coding Clinic guidance. The course includes 1 AHIMA CEU and helps coders navigate CABG procedure coding with confidence and consistency.

Included Lessons:

What is a Coronary Artery Bypass Graft?
Coronary Arteries and Vascular Anatomy of the Heart
CABG Procedure Hints and Examples
VEST™ Venous External Support in CABG Procedure
Coding Information and Coding Clinics Pertaining to CABG

Key Takeaways

Understanding of CABG Procedures: Participants will gain a comprehensive understanding of Coronary Artery Bypass Graft procedures, including the various types of grafts used and their clinical significance in treating coronary artery disease.
Anatomical Knowledge: The course equips coders with essential knowledge of coronary artery anatomy, enabling them to accurately identify and code for specific arteries and branches involved in CABG procedures.
ICD-10-PCS Coding Skills: Coders will become proficient in using ICD-10-PCS codes and guidelines to accurately document and report CABG procedures, ensuring proper coding compliance.
Operative Note Analysis: Participants will learn how to read and analyze CABG operative notes effectively, enabling them to extract critical information for precise coding.
Coding Clinic Insights: The course provides access to relevant coding clinic information, allowing coders to stay up-to-date with the latest coding practices and guidelines related to CABG procedures.
Differentiation of Graft Types: Coders will be able to differentiate between various graft types, such as arterial and venous grafts, and understand when and how to code for each type.
Sequential Grafting: Coders will learn how to code for sequential grafting procedures accurately, ensuring that the number of arteries bypassed and the vessels used are properly documented.
Harvesting Procedures: The course covers coding for graft harvesting procedures when veins or arteries are obtained from different body parts, providing clarity on when separate coding is required.
Emerging Technologies: Coders will be introduced to emerging technologies like VEST™ Venous External Support and learn how to appropriately code for these innovative approaches in CABG procedures.
Redo Procedures: Coders will understand how to distinguish between revision and redo procedures in CABG, ensuring accurate coding for each scenario.

What will I learn about ICD-10-PCS coding for coronary artery bypass graft (CABG) procedures?

This course explains how to accurately code coronary artery bypass graft procedures in ICD-10-PCS, including how to identify the correct root operation, body part, approach, and device. You’ll learn how different graft types—such as arterial and venous grafts—are represented in PCS and how operative documentation drives final code selection.

How does the course help coders distinguish between different CABG graft types and configurations for accurate coding?

The course breaks down common CABG graft options, including internal mammary artery grafts, aortocoronary bypasses, and multi-vessel bypass procedures. You’ll learn how to interpret operative notes to determine the number of coronary sites bypassed, the source of the graft, and how each graft is coded separately in ICD-10-PCS.

Will this course improve my ability to identify key documentation elements needed for compliant CABG coding?

Yes. The course highlights the critical documentation details coders must confirm, such as the coronary arteries bypassed, graft material used, number of distal anastomoses, and surgical approach. You’ll learn how to translate complex cardiac surgery terminology into accurate ICD-10-PCS codes and recognize when clarification may be needed to support compliant reporting.
