Those figures are consistent with what Issue #5 (still a couple weeks out) of this series computes from CMS NHE 2023 data and OECD health statistics. The 10-peer OECD average lands at $884 per capita, putting the US at 5.6x. Scaled to 335M people, that's $1.37T in excess admin annually.

The Woolhandler/Himmelstein 2020 figure ($812B) updates to $1.13-1.66T in 2023 dollars when adjusted for healthcare inflation. The CMS narrow admin estimate ($410B) plus CAP's billing complexity analysis ($496B) gives a $906B floor. Those three methodologies agree on the floor, disagree on the ceiling. Issue #5 covers all three and explains why the range is so wide. Coming soon.
