McCain, 80, underwent a minimally invasive surgical procedure to remove a blood clot from above his left eye on Friday and will spend the next week recovering in his home state of Arizona.
Senate Republicans were forced to postpone a vote on their party's health care bill after Sen. "His Mayo Clinic doctors report that the surgery went "very well" and he is in good spirits", the hospital said in a statement.
Two Republicans, Rand Paul and moderate Susan Collins are opposed to the new Senate bill, while many other Republican senators have voiced their concerns over the new version of the bill. John McCain's announced absence following surgery left Republicans short of votes on their marquee legislation.
One Republican opponent of her party's plan, Senator Susan Collins of ME, told CNN on Sunday, "There are about eight to 10 Republican senators who have serious concern" about the Republican replacement proposal.
Republican Senator Rand Paul also reiterated his opposition to the bill, which he described as "terrible" because it retained numerous Obamacare taxes and subsidies. According to the Washington Post, the Senate is already divided 52-49 between the Democrats and Republicans with respect to the support and opposition surrounding the legislation.
A statement from McCain's office said he would recover in Arizona this week, but neurosurgeons interviewed by the Times said that time frame could be longer. The Republican bill rolls back numerous Medicaid expansions put in place under the ACA and takes away numerous protections that the ACA forced insurance policies to have.

The five-centimeter blood clot was removed and the surgery went "very well", the hospital said.
"I don't think right now he does", he said. Shelley Moore Capito (R-W.V), Dean Heller (R-N.V.), Lisa Murkowski (R-A.K.) and Rob Portman (R-O.H.) have expressed reservations about the controversial bill, which, according to a Kaiser Family Foundation poll released July 14, is now viewed unfavorably by 61% of Americans.
The GOP was set to vote on the BCRA this week until McCain's visit to the doctor.
"There are few people tougher than my friend John McCain, and I know he will be back with us soon", Republican Majority Leader Mitch McConnell said.
Even before the delay, Mr McConnell was facing very hard odds. He is recovering at home in Arizona.
Mr. McCain's presence is crucial for Mr. McConnell to round up a decision on the bill.
