Captain Tom Moore, who has raised more than £25 million for NHS charities, will be the guest of honour at the opening of a new Nightingale hospital in his native Yorkshire next week.
The 99-year-old will praise NHS staff by video-link and said he had been “amazed by the amount of kindness and generosity from the UK public”, who have donated money to his efforts.
The Second World War veteran has captured the hearts of the nation in his attempt to complete 100 laps of his Bedfordshire garden ahead of his 100th birthday later this month.
“I think the amount raised demonstrates just how much we all value the dedication and sacrifices made by our NHS workers," Capt Tom said.
"I have fought during a war and they are now fighting in a war too.
"I’m honoured to be opening the NHS Nightingale Yorkshire and Humber and to get to thank many of the NHS workers directly.
“I know that having extra beds available for the sick, if needed will be reassuring to those workers, as it would have been to me when I was on the front line.”
The money raised by Capt Tom will buy food parcels and counselling sessions for NHS staff and electronic tablets to let patients talk to their loved ones. He initially aimed to raise just £1,000.
Sir Simon Stevens, NHS chief executive, said inviting Capt Tom to the opening was the "least we can do to thank him for his inspiring service and example".
"No doubt there will be further ways in which we will be able to express our gratitude," he added.
Capt Tom has been personally thanked by the Duke of Cambridge, who described him as a "one-man fundraising machine", while the Prime Minister's spokesman said Boris Johnson is looking at ways to recognise his "heroic efforts".
A Spitfire flypast is also reportedly being organised to mark his 100th birthday, with the Daily Telegraph reporting a team of aircraft restorers are looking to run a Second World War-era display at the end of the month.
Capt Tom, originally from Keighley in West Yorkshire, has also released a charity cover of You'll Never Walk Alone with Michael Ball.
