RESUMO
PURPOSE: To evaluate the results of a privileging program aimed to ensure that health care providers and facilities adhere to standards of care. MATERIALS AND METHODS: Technical and professional privileging applications were mailed to more than 1,800 diagnostic imaging facilities and more than 6,000 professional providers of services to members of a health care plan. Site inspections were used to determine whether facilities met standards of care. Specialty providers were assigned a range of current procedural terminology codes for which they had privileges to bill the payer. RESULTS: Of 1,004 imaging sites inspected, 197 (20%) failed with the ability to remedy the violation, 106 (10%) failed with fundamental and serious deficiencies, and 701 (70%) passed. Site inspection pass rates varied substantially by specialty. Chiropractors and podiatrists were more likely to fail than medical and surgical specialists. A strong correlation was found between refusal to participate in the inspection and failure rate. Results suggest that reduction of the number of professional claims billed led to a 2% decline in total imaging expenditures, or a more than 10:1 return on the cost of implementing technical and professional privileging programs. CONCLUSION: Health care plans can positively influence costs and quality by developing, monitoring, and enforcing their own quality standards for diagnostic imaging.
