Percentage of final reports for patients aged 18+ years undergoing CT with documentation that 1+ of following dose-reduction techniques were used
Automated exposure control
Adjustment of mA &/or kV according to patient size
Use of iterative reconstruction technique
Rationale
There are estimates that CT scans account for 17% of total imaging procedures performed in United States each year and 49% of collective radiation dose from imaging procedures. Current advances in technology have resulted in several methods to reduce radiation dose for patients undergoing CT. Studies show that CT dose-optimization techniques can reduce radiation dose by 40-50% without sacrificing image quality or diagnostic ability.
Instructions
This measure is to be submitted each time patient has CT scan during performance period. There is no diagnosis associated with this measure. It is anticipated that Merit-Based Incentive Payment System (MIPS)-eligible clinicians who provide professional component of diagnostic imaging studies for CT will submit this measure.
Numerator
Final reports with documentation that indicate individualized dose-optimization technique was used for performed procedure. Dose-optimization techniques include following
Automated exposure control
Adjustment of mA &/or kV according to patient size
Use of iterative reconstruction technique
Denominator
All final reports for patients aged 18+ years undergoing CT
