AHA Coding Clinic® for ICD-9 - 2010 Issue 4; Volume 3 New/Revised Codes
Thoracoscopic and Thoracoscopically-Assisted Ablation of Heart Tissue (Maze Procedure)
Effective October 1, 2010, a new code has been created to specifically describe the maze procedure performed via a thoracoscopic approach or a thoracoscopically-assisted approach (37.37). Previously the procedure classification only provided codes for maze procedures performed via an open chest approach (37.33) and an endovascular approach (37.34). The maze procedure is a surgical approach used to treat atrial fibrillation by creating lines or scars which block conduction pathways in the heart itself. The classic maze procedure is performed through an open chest approach, creating the lines with a scalpel by a carefully placed pattern of...

Article Overview
This coding update article covers an ICD procedure classification change affecting the maze procedure and related ablation of heart tissue. It is intended for coders, CDI staff, and reimbursement professionals who need to understand how the procedure taxonomy was revised across open, endovascular, and thoracoscopic approaches. The article also discusses the clinical and technical context for the different surgical access methods and the related exclusion structure in the code set.
Why This Topic Matters
It helps readers understand a newly added procedure classification for thoracoscopic heart-tissue ablation and how it fits among other maze-procedure approach categories.
Article Sections
-
