The Morrison government is still planning on making changes to the disability insurance scheme this year, the responsible minister has confirmed.
National Disability Insurance Scheme Minister Linda Reynolds had put legislative changes to the program on hold while consulting with the sector, but she is still working towards introducing them this year.
"I'm very keen and very aware that I do need to bring forward legislation this year to improve the participant experience," she told a Senate inquiry on Tuesday.
"Particularly in terms of some form of independent assessments in conjunction with changing the legislation for how people are reassessed."
Senator Reynolds flagged the possibility of pushing annual assessment out to every three or five years.
The Senate inquiry is solely looking at independent assessments, which had been previously announced by Senator Reynolds' predecessor Stuart Robert.
Recommendations from the inquiry will help shape how independent assessments work and the form they take.
People applying for the NDIS are assessed by their own medical team to determine what level of support they require from the scheme.
But Senator Reynolds says that system is currently unfair, raising concerns people with better access to doctors were receiving more from the NDIS.
But by 2024/25 the federal government expects to be paying 61 per cent of the scheme, with the states dividing the rest.
The NDIS is growing at about 12 per cent each year.
Last week's federal budget showed the cost of participant plans in the scheme would grow to $31.9 billion in 2024/25.
"To be quite frank it is now a scheme that is on an unsustainable growth trajectory," Senator Reynolds said.
"Together we've got to find a sustainable growth trajectory so the scheme itself endures for many generations to come."
NDIS packages are built on what is deemed "reasonable and necessary" for participants.
The phrase would be redefined to ensure its meaning is clearer and consistent, Senator Reynolds said.
