Item/Service Description A. General
This procedure involves inserting a balloon catheter into a narrow or occluded blood vessel to recanalize and dilate the vessel by inflating the balloon. The objective of PTA is to improve the blood flow through the diseased segment of a vessel so that vessel patency is increased and embolization is decreased. With the development and use of balloon angioplasty for treatment of atherosclerotic and other vascular stenoses, PTA (with and without the placement of a stent) is a widely used technique for dilating lesions of peripheral, renal, and coronary arteries.
Indications and Limitations of Coverage B. Nationally Covered Indications
The PTA is covered to treat the following indications:
- Atherosclerotic obstructive lesions:
- Effective July 1, 2001, Medicare covers PTA of the carotid artery concurrent with carotid stent placement when furnished in accordance with the Food and Drug Administration (FDA)-approved protocols governing Category B Investigational Device Exemption (IDE) clinical trials. The PTA of the carotid artery, when provided solely for the purpose of carotid artery dilation concurrent with carotid stent placement, is considered to be a reasonable and necessary service only when provided in the context of such a clinical trial.
- Effective October 12, 2004, Medicare covers PTA of the carotid artery concurrent with the placement of an FDA-approved carotid stent for an FDA-approved indication when furnished in accordance with FDA-approved protocols governing post-approval studies. CMS determines that coverage of PTA of the carotid artery is reasonable and necessary under these circumstances.
C. Nationally Noncovered Indications
- Performance of PTA in the carotid artery when used to treat obstructive lesions outside of FDA-approved protocols governing Category B IDE clinical trials and outside of FDA-required post approval studies remains a noncovered service.
- Performance of PTA to treat obstructive lesions of the vertebral and cerebral arteries remains noncovered. The safety and efficacy of these procedures are not established.
D. Other
All other indications for PTA for which CMS has not specifically indicated coverage remain noncovered.
