There are now 10 administrators for every 1 doctor.
Since 1970, the number of physicians has increased by 2x. The number of administrative staff has increased by 38x.
If each administrator is making 100k+ - 150k+, that's significant cost.
Some of these crazy billing practices are due to the private equity buy-ups and consolidation, creating workflows and fee structures that are hostile to patients and doctors, but benefit the PE firms.
