The nursing company that employed the women, which the Daily Mail declined to name, confirmed that the female proprietor had received several complaints from nurses before parting ways with previous year.
Lee attended The Chicago Comic & Entertainment Expo (C2E2) on April 21-23 which is when the alleged attack is believed to have happened.
However, through his personal lawyer Tom Lallas, Stan Lee has once again categorically denied the allegation by the masseuse and is claiming this is another attempt at extorting money or a "shake down" as reported by Daily Mail.
"Stan is an old man who has seemingly lost his way", a source told Daily Mail.
Because of these claims, the nursing company is in a legal dispute with Lee, although it is understood no legal claim has been filed.
The company ceased working for him at the end of 2016.
According to a report from the Daily Mail, which cites anonymous sources, the 95-year-old Lee is now in a legal dispute with a nursing company over claims that he sexually harassed and groped multiple female nurses who were employed to care for him at his home in West Hollywood, Calif.

Lee is the co-creator of some of Marvel's most popular characters, including Thor, Spider-Man and the X-Men.
'She claims Stan was out of control, he groped her and asked her for sex which the woman refused.
The source added: 'While people might think Stan is a frail and fragile old man, that's not the case. In July of 2017, Lee was widowed when his wife of 70 years, Joan, passed away.
In a separate statement, Mr. Lallas said "fully intends to fight to protect his stellar good name and impeccable character".
A representative for the new nursing company caring for Lee said he has been "polite, kind and respectful" to the nurses. According to Lallas, Lee was asked to pay money under threats the accuser will go to the media.
"I have no comment except that I have not asserted any legal claim against Mr".
According to reports, Lee is accused of groping the home-care nurses, requesting sexual favors and walking around naked in his home while the nurses were present.
