Shannen Doherty's lawyers are bringing attention to phone calls allegedly made by employees of the actress' former business management firm, Tanner Mainstain.
The Beverly Hills, 90210 star filed a lawsuit in August against her former business managers, claiming that they failed to pay her medical insurance premiums, which led to her being uninsured for several months. Doherty was diagnosed with breast cancer, and claims that it metastasized while she was not insured and therefore unable to regularly see a doctor.

On Monday, a motion filed by Doherty's legal team and obtained by ET claims a phone conversation took place between an operator at the Screen Actors Guild Health Plan and an employee of Tanner Mainstain on July 8. "I'm wondering if you can help me, and I know this might sound a little stupid," the woman allegedly tells the operator. "I need to know where my billing statement was mailed on January of 2014 if that's possible."
The motion further claims that it is explained to the woman calling that the premiums department can deal with her inquiry but verification would be needed going forward. When asked her name, the woman allegedly responds, "Shannen Doherty."

That same day, the motion also claims that SAG Health Plan received another call, allegedly from another Tanner Mainstain employee, looking to get billing information for a client. The motion alleges that the caller inquired about Doherty, who was no longer a client for the business management firm at the time, and the actress' social security number was allegedly given for verification in order to obtain certain information.
Doherty's legal representation alleges that these phone calls were made "in order to obtain access to Ms. Doherty's confidential medical information for use in this litigation."

"The illicit conduct by Tanner Mainstain’s employees detailed in this motion speaks volumes regarding the integrity and credibility of this business management firm," Doherty's attorney, Devin McRae, told ET in a statement. "Something to think about when they ask you for complete control over your finances and a power of attorney."
The business management firm has yet to comment on this latest motion but did release a statement to ET when the lawsuit was originally filed in August.
"Tanner Mainstain is saddened to learn that Ms. Doherty is suffering from cancer and wishes her a full recovery," the statement reads. "However, the claim that Tanner Mainstain caused her to be uninsured, prevented her from seeking medical care, or somehow contributed to her cancer is patently false. Tanner Mainstain will aggressively defend all of Ms. Doherty's claims in court."
