LOS ANGELES, Calif. (CN) - Kaiser and an insurance administrator are liable for withholding proper long-term disability coverage to a woman who is bipolar and unable to work, she claims in court.

Christine Yeigh, a registered nurse, says she was diagnosed as bipolar, psychotic “at times” and suffers from “magical” thinking, on top of several other medical conditions, including panic disorder, agoraphobia, depressive disorder, spinal stenosis, cervical spinal stenosis and lumbosacral spondylosis.

Despite the diagnosis, Yeigh claims Metropolitan Life Insurance Company declared her ineligible for long-term disability based on reports by company consultants.

“Metlife’s IPCs (independent physician consultants) concluded that the medical documentation on file would not support psychiatric functional limitations and restrictions beyond Jan. 6, 2012 and continuing,” according to the complaint.

Yeigh, 66, says she is “unable to perform with reasonable continuity the substantial and material acts necessary to pursue [her] usual occupation in the usual and customary way” as defined by the provisions of her MetLife-Kaiser plan.

She now receives Social Security benefits, but claims MetLife owes her over “$4,000 per month in benefits.

Yeigh sued MetLife and Kaiser Foundation Health Plan Inc.’s Long Term Disability Plan under the Employee Retirement Income Security Act and state law. She seeks the benefits owed her, plus attorneys’ fees and costs.

Yeigh is represented by Kevin Zietz in Encino, Calif.
