Looking at the CDC site you linked to, it looks like they have 38,576 COVID-19 deaths, while over to the right they have another 17,122 people listed as “Deaths with Pneumonia and COVID-19”. Maybe they’re separating the two and worldometers is lumping all of them together?
The left hand column [COVID-19 Deaths (U07.1)] is highlighted as bold. This would suggest that that this is the total number. It does not state that these are COVID-19 (U07.01) alone. The footnote states, “Deaths with confirmed or presumed COVID-19, coded to ICD–10 code U07.1.” My reading is that the column to which you refer [Deaths with Pneumonia and COVID-19 (J12.0-J18.9 and U07.1)] is an intersection of COVID-19 deaths and Pneumonia deaths, that the COVID-19 deaths here are included in the number in the first column. In any case, their total is still only 55,698 which is still less that 69,611 that Worldometer.info is reporting.
