The deaths were between January 17 and March 6, with the majority being on or after March 3.
The time taken for positive results to be received is among the potential factors in a delay between a death happening and being recorded.
Patients were aged between 34 and 97. All except three, aged between 54 and 87, had known underlying health conditions.
Since April 28 2020, NHS England and NHS Improvement also started to report the number of patient deaths where there has been no Covid-19 positive test result but it is documented as a direct or underlying cause of death in the death certification process.
The figures for the latest reporting period show there were 20 such deaths in England.
