Representative Experience

  • Represented managed care company in parallel federal and state lawsuits against hospital systems seeking over $46 million in statutory penalties for alleged violations of the Texas Prompt Pay Act on self-funded medical claims. The Fifth Circuit held statutory penalties cannot be imposed upon self-funded plans and that our client was not liable to the hospital systems.
  • Represented managed care client in an AAA arbitration filed by a hospital system alleging violations of the Texas Prompt Pay Act that applies statutory penalties to medical claims that are not reimbursed within 30 days of submission. The hospital system alleged our client failed to timely pay thousands of hospital claims over a four-year period and sought $144 million in damages. Following a five-day arbitration hearing, the arbitrator ruled in our client’s favor on all legal issues and awarded the hospital roughly 1% of its requested damages.
  • Represented managed care company in arbitration proceeding in which a physician group sought in excess of $6,000,000 arising from alleged prompt pay violations on 30,000 claims for services provided over a five-year period. The physician group also alleged that the managed care company made misrepresentations in connection with the applicable fee schedules and failed to adequately disclose fee schedules and changes to those schedules. Following a five-day arbitration hearing, the arbitrator found that the managed care company had properly paid all claims except for a small number that were corrected and paid before the arbitration hearing. The arbitrator also found that no misrepresentations had been made and that fee schedules were properly disclosed.
  • Obtained take-nothing jury verdict for health insurance/managed care company in a suit filed by a local hospital in Gulfport, Mississippi, alleging breach of a managed care agreement, breach of the duty of good faith and fair dealing, and mutual and unilateral mistake seeking damages of $1.6 million. The hospital demanded new contract terms after determining that a pricing amendment that it signed had not yielded the increase in revenues that its Director of Managed Care, CEO and Board of Trustees expected. When the managed care company client refused to meet the hospital's demands, the hospital terminated the agreement and filed suit. The jury returned a unanimous verdict in favor of the firm’s client.
  • Represented insurance company in business disparagement, tortious interference with business relations case filed by a provider seeking unspecified actual and exemplary damages arising from insurance fraud investigation. After removal from state to federal court, the case was transferred to multi-district litigation and all claims against the firm's client were ultimately dismissed.
  • Represented insurance company in jury trial on defamation claims filed by a provider in which federal district judge granted judgment as a matter of law during the plaintiff’s case in chief.
