The veterans were originally awarded $887.8-million over the long-standing federal practice of clawing back the military pensions of injured soldiers by the amount of disability payments they received.
The latest amount approved was for a settlement on the cost of living provisions in that agreement.
The lawyers for the veterans said they found a miscalculation in the way the federal government determined the cost of living allowance for military veterans.
The original class action was initiated in March 2007 on behalf of representative plaintiff Dennis Manuge and other disabled Canadian Forces veterans affected by the clawbacks.
The lawsuit started with 8,000 people, but the $38.6-million settlement includes another 6,000 veterans who were not subject to a wrongful offset of their benefits, but whose cost of living allowances were also miscalculated.
Lawyers for the plaintiffs have said the cost of living issue wasn't included as part of the original settlement because there wasn't enough time and the two sides agreed to deal with it at a later date.
Manuge has said the issue has been resolved fairly and reasonably.
Lawyers say the payments begin in January 2015 and will be paid out over a year.
