Raber I, Al Rifai M, McCarthy CP, et al. - Findings indicate that Centers for Medicare & Medicaid Services (CMS) payments may potentially differ between men and women cardiologists, and the likely reason for this is gender disparities in the number and types of charges submitted. Further research is needed for exploring mechanisms behind these differences.

• This is a cross-sectional study of 20,273 cardiologists who received reimbursements from the US CMS in 2016.

• Higher median reimbursements were received by men vs women in both inpatient ($62 897 vs $45 288) and outpatient ($91 053 vs $51 975) settings.

• More median charges were submitted by men in the inpatient (1190 charges vs 959 charges) and outpatient settings (1685 charges vs 870 charges).

• Gender difference in payments remained even post-adjustment for physician experience and subspecialty, number of charges submitted, and Medicare beneficiary features.
