Documentation Required
- Clinical justification must be provided to indicate when post-operative tests (endocardial catheter electrophysiology study; 24-hour Holter monitor; exercise stress test; color-flow Doppler of transmitral/transtricuspid flow) are 'clinically indicated' if performed, because they are not routinely medically necessary.
- Adequate documentation of the nature and extent of intolerance to antiarrhythmic or other drug therapy when 'cannot tolerate the side effects of drug therapy' is asserted.
- Documentation of prior adequate attempts at medical management when claiming 'hemodynamic consequences of chronic atrial fibrillation/flutter despite adequate attempts at medical management.'
- Documentation supporting high risk for thromboembolism, specifically either: records showing a previous episode of thromboembolism with other sources of emboli ruled out; OR documentation of long-standing atrial fibrillation in members with mitral valve disease who are undergoing open surgical repair of the mitral valve.
