Roddick lost his serve for the only time in the match following the row, but recovered to win the decisive set.
Earlier, Rainer Schuettler beat Guillermo Coria 6-3 4-6 6-2 in the Red Group they share with Roddick.
The American, who is battling with Spaniard Juan Carlos Ferrero to end the season as world number one, launched into a heated exchange with umpire Mike Morrissey over his second-set ruling.
Roddick, who served 14 aces, broke Moya three times in the first set, blasting the Spaniard with his powerful serve and superior shotmaking.
But Roddick never did regain that dominance he had
enjoyed after his verbal volley at Morrissey.
The turning point came in the second game of the second set after Roddick sent a backhand wide to give Moya his first break
Roddick hit a serve that he thought was an ace but instead was
dubbed wide by Morrissey.
Roddick accused the umpire of being "blind", before serving a double fault to hand Moya the break for a 2-0 lead in the set, and was still livid at Morrissey after Moya held again for a 3-0 edge.
"It affected me the next game," admitted Roddick. "I try to let it go pretty quickly.
Schuettler will next face Moya and Roddick
"I probably should have kept it together a little bit more and not hit an angry double-fault.
"But luckily I was able to recover in time for the third set."
Moya took advantage of the break to win the second set, but never broke Roddick again.
Roddick broke Moya in the eighth game of the third set, taking advantage of three consecutive errant forehands by the Spaniard for the break, then holding serve for the triumph, the last point coming when Moya sent a backhand wide.
Schuettler took the early advantage against Coria, breaking at the first time of asking and then holding points for a 4-0 lead.
And although Coria hauled back to 3-3, Schuettler won the next three games to clinch the set.
Coria took a 3-0 lead in the second set, and went on to win it 6-4.
Schuettler opened a 4-1 lead in an error-strewn third set and then broke again to win it 6-2.
