We analyzed Medicare claims records for people who had first-time atherectomies between 2019 and 2022 and found that nearly 1 in 4 patients underwent the invasive procedure after only a diagnosis for claudication, indicating an early stage of vascular disease. This amounts to nearly 30,000 patients who may have undergone procedures too soon or possibly even unnecessarily. Some doctors stood out because of the money they made. Dr. Amiel Moshfegh, a Beverly Hills radiologist, received $45 million from Medicare over five years for performing thousands of atherectomies, according to public Medicare records.
