AHA Coding Clinic® for ICD-9 - 2006 Issue 4; VOLUME 3 NEW/REVISED CODES
Transmyocardial Revascularization
Effective October 1, 2006, new codes have been created for endoscopic and percutaneous transmyocardial revascularization. Transmyocardial revascularization (TMR) is a procedure that uses a laser to bore holes through the myocardium to restore perfusion to areas of the heart where blood flow may be impaired due to diseased or clogged arteries. It is used to relive severe angina or chest pains in patients who are not suitable candidates for angioplasty or bypass surgery. Prior to this change, both percutaneous and thoracoscopic approaches for TMR were coded to 36.32, Other transmyocardial revascularization. The totally endoscopic technique requires four thoracoscopic...

Article Overview
This article covers a procedural coding update for transmyocardial revascularization (TMR), a laser-based heart procedure, with emphasis on the shift to new procedure codes effective October 1, 2006. It is relevant to coders, billers, and reimbursement professionals working with cardiovascular procedures and hospital coding changes. The discussion also notes the relationship between endoscopic, thoracoscopic, percutaneous, and robot-assisted approaches at a high level, along with the prior code assignment that was in use before the update.
Why This Topic Matters
Coding changes for procedural services affect claims accuracy, code selection, and historical comparisons across date of service. Understanding the update helps readers recognize which procedure category changes were introduced and how the article frames the transition period.
