On Sunday, he announced he was looking to change the bill that opponents have dubbed "RyanCare," specifically its treatment of people in their 50s and 60s.
"We believe we should have even more assistance ... for that person in their 50s and 60s because they experience higher health care costs," Ryan said Sunday morning on Fox News.
Ryans iad he still expected the bill to pass the House on Thursday.
The bill, hailed by Ryan and other Republicans as a viable replacement for the Affordable Care Act, lost some political momentum after a Congressional Budget Office review found 24 million people would lose coverage if the bill were to become law.
Ryan and other proponents have argued the CBO is not a credible source of data. Others have argued that the number of people insured is not a reliable metric, since it would drop the ACA penalty for not having insurance.
If we accept the status quo, our health care system will collapse and all of us will suffer as a result.
Ryan said the CBO review did not take into account the plans to reduce regulations in the health care industry, which would drive prices down and make coverage more affordable for senior citizens. However, he said "even with that ... we should be offering more assistance than what the bill currently does."
The bill has drawn widespread criticism from Democrats and some Republicans. Conservatives like Sen. Tom Cotton (R-AR) say the bill doesn't go far enough and won't pass the Senate even if it passes the House.
Rep. Brian Fitzpatrick (R-PA) blasted the bill Saturday night.
