Another lawsuit accuses a former physician assistant at a Veteran's Administration hospital in Kansas of sexual abuse.

The suit filed Tuesday in federal court alleges that Mark Wisner suggested he would withhold pain medication if the patient didn't permit unnecessary and improper genital examinations at the Leavenworth VA Medical Center. Wisner, the hospital and the federal government are named as defendants. At least five other lawsuits have been filed against Wisner.

Wisner surrendered his medical license last year after at least seven patients accused him of abuse. Criminal charges that include sexual battery are pending in Leavenworth County.

No attorney is listed for Wisner in online court records for the latest lawsuit. The hospital has said it stopped Wisner from seeing patients and began an investigation after the allegations surfaced.
