The Lakers, outplayed down the stretch by Denver's bench, got 29 points and 12 assists from James, who hit two 3-pointers in the fourth quarter. Anthony Davis had 27 points and Kuzma 25.
P.J. Dozier had a chance to put the Nuggets up by one with 4.4 seconds left but missed the second of two free throws. Kuzma rebounded and the Lakers called timeout to set up the winning play.
"I got an open look. It's a play we ran in practice a few times prior to the restart," Kuzma said. "Coach had faith in me, called my number and it paid off. It just shows that my teammates and my coaches, they trust in me, the trust they have in me, every time we ran that play in practice I've kind of hit that shot. Obviously the play 9 out of 10 times is going to LeBron, but they called my number. It's all about trust."
Dozier had been fouled by Kuzma while driving the lane after a miss by James.
James had given the Lakers a 121-119 lead by converting a 3-point play with 45.7 seconds to go. Monte Morris made one of two free throws for the Nuggets.
The Lakers had clinched the No. 1 seed in the Western Conference before their losing streak started. They are 3-4 in the bubble with one game to go.
"I think the biggest thing is for us to build habits, winning championship habits, especially since we locked up first place," Kuzma said. "There's a little bit of time you can chill and relax. We don't really have that margin for error. Like most teams, we have new parts and are trying to fit new guys in and I think the biggest thing, is try to build camaraderie with the new group."
Dozier scored 18 and Michael Porter Jr. had 15 for the Nuggets, who are currently the No. 3 seed in the West.
"I couldn't be more proud of our group," Denver coach Michael Malone said. "They played extremely hard against the No. 1 seed in the Western Conference. It was the fourth time we played them and every game has been a battle down to the wire. For us to sit out starters the whole fourth quarter and to have the guys on the bench out there giving them all they could handle, it was a heartbreaker. It's always tough, but just so proud. I could not ask for a greater effort, greater focus, energy, whatever you want to call it."
The Lakers took an 87-80 lead late in the third quarter after two buckets by Kuzma and two free throws by Davis. But the Nuggets went on an 8-1 run to finish the quarter in an 88-88 tie. Mason Plumlee made a jumper and Bol Bol and Morris each made a 3-pointer
Davis grabbed the rebound of Kuzma's miss for a slam dunk at the halftime buzzer that gave the Lakers a 64-59 halftime lead. Davis also made a similar play off miss by Kuzma in the last minute of the first quarter.
Lakers: Dion Waiters had 12 points in 12 minutes off the bench in the first half. ... Davis had big plays on both ends during a sequence in the first quarter, when he stole the ball and then took a pass from James for a layup.
