For the first time ever, the 'Special Recognition Award' will be handed out when the ceremony takes place at the O2 Arena in London on February 20.
The award will be awarded by charity War Child, which celebrates its 20th anniversary next year, after changing and saving the lives of over 800,000 children in the world's most war-torn countries.
"For two decades now, War Child has worked with artists to raise funds and awareness to help children whose lives have been torn apart by war," Brits Chairman David Joseph said.
"The Brits are proud to give recognition for their vital work as well as saying thank you to all the artists who have given their time, help and energy to something so important."
The past two decades has seen War Child produce albums, hit singles and memorable concerts to support their cause.
Paul McCartney, Radiohead, Blur, Manic Street Preachers, Oasis, Paul Weller and The Stone Roses, amongst others, joined forces to record the Help album in just 24 hours back in 1995.
Coldplay, The Killers, Bono and Gary Barlow also shared the stage at London's Shepherds Bush Empire, at a War Child concert in 2009, which also marked the re-launch of the historic gig venue.
"A lot of people say that music cannot change the world… I think it really can make a difference," said McCartney.
"Music can make people aware, put the issue into focus and shine a spotlight on the bad stuff. It also eats away at the horrors and alleviates some of the pain by raising the money to help these children.
"I have been supporting War Child since 1995. Their work saves lives. I urge everyone to support War Child."
The decision to present the 'Special Recognition Award' means that the 'Outstanding Contribution Award' will be rested in 2013.
The winner of the Critics' Choice and full category list will be announced on December 20.
