 WellCare has said that its normal business operations have not been affected by the federal and state investigations, and that it remains financially sound, with over $1 billion in cash and cash equivalents.In a now-unsealed plea agreement, prosecutors and a former employee said the company inflated expenditures by submitting fake documents to the state.Under some mental health care contracts, WellCare was paid a flat per-patient fee and required to spend at least 80% of it on care.
