Murray, who won Olympic singles gold at London 2012 last year before returning to SW19 to claim his first Wimbledon career title this summer, went under the knife to fix a back problem.
The 26-year-old opted for surgery shortly after leading Great Britain back to the Davis Cup World Group with a play-off victory over Croatia in Umag.
Murray, who also won Olympic mixed doubles silver with Laura Robson last summer, could return to training in November having lost in the quarter-finals on his last Grand Slam outing at the US Open.
And he appeared in good spirits after the surgery to fix a disc problem in his lower back, posting a picture on Twitter from his hospital bed with both thumbs up.
