According to a Plastic and Reconstructive Surgery study that was trying to determine if gender-related billing and coding differences may be related to the income gap, was found to be true. The results found that significant differences were found between male and female surgeons in work relative value units billed, work relative value units billed per case, and the numbers of major cases performed. The average total work relative value units for male surgeons was 19.34% higher than for female surgeons. Male surgeons performed 14.28% more major cases than female surgeons. Potential explanations include practices focusing on larger and more complex operative cases and differences in coding practices.
