The amounts paid for services under the National Disability Insurance Scheme could go up after an annual pricing review.
The minister responsible for the NDIS, Stuart Robert, announced the 2020-21 review would start on Wednesday.
It will examine existing price limits and related policies, check whether they are still appropriate in the current market, and recommend changes where needed.
"This pricing review is part of our commitment to building confidence and certainty for the provider market, as well as ensuring participants are able to access supports that represent value for money," Mr Robert said.
The NDIS has faced criticism that the prices it pays for services aren't high enough to cover providers' costs in meeting the often-complicated needs of people with disabilities.
Those people, their families and carer, providers, peak bodies and community representatives will be able to give comments to the review.
Submissions close on February 3, 2020.
Any changes will take place from July 1, 2020 and be announced at least a month before then.
