Evolution of carotid stenting: payment issues.

Area of Science:

• Interventional Cardiology
• Vascular Surgery
• Health Policy

Background:

• Carotid stent placement is an interventional procedure.
• CPT codes were developed to report carotid stent procedures.
• The Centers for Medicare and Medicaid Services (CMS) established a coverage policy.

Purpose of the Study:

• To outline the Current Procedural Terminology (CPT) codes for carotid stent placement.
• To detail the eligibility criteria for Medicare coverage of carotid stenting.

Main Methods:

• Assignment of two Category I CPT codes for carotid stent placement (with and without embolic protection).
• Establishment of Medicare coverage policy by CMS in March 2005.
• Definition of patient eligibility criteria for Medicare coverage.

Main Results:

• Two CPT codes were created, encompassing all associated procedures.
• Medicare coverage is restricted to patients with specific clinical criteria and embolic protection.
• Coverage is limited to facilities meeting CMS certification requirements.

Conclusions:

• CPT codes for carotid stenting include comprehensive procedural elements.
• Medicare coverage for carotid stenting is highly restrictive, focusing on high-risk patients with embolic protection.
• Ongoing reconsideration of coverage criteria for asymptomatic patients is noted.
