The 'Rocket Man' singer spent two nights in intensive care after becoming "violently ill".
Sir Tom Jones said it was 'a great honour' to be awarded the prize
The 73-year-old star will be honoured for his five-decade music career at a ceremony on 4 July. Organisers described Sir Tom as "a living legend" whose music had "brought pleasure to many people".
The Silver Clef Awards raise funds for the charity Nordoff Robbins to provide music therapy for adults and children.
"To be presented with the lifetime achievement award is a great honour," Sir Tom said.
"I've seen first hand the amazing results that the dedicated and skillful therapists get with children and adults - it's work that really makes a difference.
"This is a wonderful and important charity, so to be recognised for my lifetime of work means a great deal."
The singer first rose to fame as a solo singer in the 1960s with hits including It's Not Unusual, What's New Pussycat? Green, Green Grass of Home and Delilah.
Jones has sold more than 100 million records around the world, achieving 46 top 40 singles in the UK and 19 in America.
