If the Republican's push to repeal the Affordable Care Act carries out, then UnitedHealth (UNH - Get Report) stock is going to benefit, TheStreet's Jim Cramer claimed on CNBC's "Squawk on the Street" on Thursday. 

"I remain convinced that the only way to play that appeal is UNH," he said. 

UnitedHealth reported a top and bottom line beat for the 2016 fourth quarter earlier this month. After the earnings release the stock dropped down to $158 because people always wait five days to snatch it up, Cramer claimed. Sure enough, "Bingo!" it went up to $163 five days later, and it will go to $170 on the repeal, he said. 

Some analysts believe UnitedHealth, Aetna (AET) and Humana (HUM - Get Report) will actually benefit from the ACA repeal because it may force them to turn to the employer market, which has healthier individuals. 

"It was supposed to be bad for the hospitals, but the hospital stocks haven't come down," Cramer pointed out.
