The 24-year-old, one of the most combustible characters in tennis, was fined $113,000 over a meltdown in Cincinnati last month and courted more trouble with the governing body of men's tennis at the U.S. Open describing them as corrupt.
"The investigation found a pattern of behavior related to Kyrgios's verbal abuse of officials and/or spectators in the past 12 months that constitutes a violation," the ATP said in a statement, adding that Kyrgios had five working days to appeal.
Both the fine and suspension are deferred pending Kyrgios's compliance with a set of conditions which will apply at ATP and Challenger Tour events during a six-month probationary period.
Some of the conditions include no further code violations that result in a fine for verbal or physical abuse of officials, fans or any others on-court or on-site and unsportsmanlike conduct and any obscenity directed at officials.
Kyrgios was also told to seek "continued support" from a mental coach during tournaments and consult a professional specialising in behavioural management in the off-season.
The ATP added that a second investigation had taken place after Kyrgios's comments at the US Open, although the world number 27 had clarified his remarks saying that "corrupt" was not the correct choice of words.
"Following a clarification issued by the player... it was determined that the incident did not constitute a Player Major Offense and no additional penalties were applied," ATP added.
