See their Figure 1 where they plot the hospitalization rate during the Wuhan epidemic against US hospital bed capacity to give an idea of how quickly the US would be overloaded in a “Wuhan-like outbreak”. They consider ICU beds (2.8 per 10000 adults), empty ICU beds (31.8% of all ICU beds), and what they call “US inpatient beds in community hospitals” (29.7 per 10000 adults). The sum of ICU and community beds comes out to ~850000 based on an adult US population of 240 million, which isn’t too far off from your 924107 number.
Two things to keep in mind for working through your question about the implications of 10^6 (concurrent) cases (I see these are reiterating points Mark already made): On the one hand, most symptomatic cases will not need hospitalization. On the other hand, most hospital beds are occupied (~70% of ICU beds, which roughly agrees with Mark’s 66% estimate for overall beds), so the number of available beds is much less than the total number of staffed beds.
I’ve heard it suggested that today’s declared national state of emergency and associated funding may enable things like FEMA building field hospitals to extend hospital bed capacity.
