In the aftermath of Washington, DC's Citi Open cancelling there is growing speculation the US Open is in jeopardy.
The 2012 US Open champion says he's mentally ready to play in New York if it's safe to do so.
"Four or five weeks ago, we were pretty skeptical about it," Murray told BBC Sport's Russell Fuller. "But mentally at some stage you need to start preparing and planning for that.
"If it wasn't happening, my schedule for practicing, my rehab, would all be a bit different. Mentally I'm planning for it to go ahead."
The 33-year-old Murray, who defeated Stan Wawrinka in the Antwerp final last fall to claim his 46th career title, hasn't played a Tour-level match since representing Great Britain in the Davis Cup final last November.
In his last US Open appearance, Murray lost to Fernando Verdasco in the 2018 second round. The three-time Grand Slam champion has reached the quarterfinals or better in five of his last seven Flushing Meadows appearances.
Murray, who is playing next week's Battle of the Brits, is reportedly interested in a wild card for the Western & Southern Open, which will be played at the Billie Jean King National Tennis Center before the US Open.
"The issue for us is the travel, so we'll probably be a bit apprehensive getting over there," Murray told BBC Sport. "Hopefully the US Open can go ahead, and it's OK. But if not, I'm also OK with that. It's not like I'm saying it must go ahead.
"So long as it's safe for the players then we need to try to get back to competing when it's safe to do so."
