Katyana Kass fainted in her mother's luxury Hollywood apartment block Sierra Towers and struck her face after a swimming session in January (12).
Kass was checked into the city's Cedars-Sinai hospital, where she underwent surgery to have metal pins inserted in her face.
Collins has now launched legal action action, filing a lawsuit in L.A. Superior Court, according to Britain's Mail on Sunday newspaper.
She claimed Kass, 27, collapsed with suspected hypothermia and a security guard called in to help failed to care for her properly.
Collins is suing for reimbursement of medical and legal bills, as well as damages.
