It only applies to Medicare (USA) patients.
After a 4 week stay in hospital 30 years ago, I heard nurses speak openly about exaggerating the condition of patients to get more weekly budget allocation. When I hear allegations of exaggerating patients diagnosis or cause of death during covid, I don't find it surprising at all.
