Clinical services provided by interventional radiologists to Medicare beneficiaries in the United States, 2000-2003.
To identify trends in Evaluation and Management (E&M) and non-E&M services of interventional radiologists (physician specialty type 94) from 2000 to 2003 for Medicare patients, Medicare Part B physician annual allowed services data from the Centers of Medicare and Medicaid Services (CMS) were analyzed for all interventional radiologists from 2000 to 2003. Because the number of interventional radiologists in the United States according to the Society of Interventional Radiology is, on average, 4.2 times the number of interventional radiologists who use physician specialty type 94, we extrapolated the E&M services for each year. During the period examined, the total number of E&M services by interventional radiologists increased 309%, from 9,698 in 2000 to 29,914 in 2003. The most commonly performed services were Office or Other Outpatient Visit (Current Procedural Terminology [CPT] codes 99211-99215) for established patients, followed by Subsequent Hospital Care (CPT 99231-99233) and Office or Other Outpatient Consultations (CPT 99241-99245). The extrapolated number of E&M services by interventional radiologists for Medicare patients in 2003 is approximately 107,853. The number of Office and Outpatient Visits for New Patients (CPT 99201-99205) increased 142%, whereas the number of Consultations for New Patients (CPT 99241-99245) increased 208%. The total number of codes reimbursed by CMS to interventional radiologists (type 94) increased from 2.8 million in 2000 to 3.8 million in 2003.
