Figures from 2016 showed the cost of providing free bus travel up to that point was in the region of £840m.
A Welsh Government official said Wales was the first country in the UK to introduce free bus travel for older people.
"We will be doing further work to develop a more flexible and long-term approach towards fare concessions, considering financial implications and passenger need," the spokesperson said
"As a result of this additional work, this policy area will not be included in the forthcoming bus legislation," they added.
