Representative Matters

  • Arbitration: Represented a large physician group against a national laboratory corporation alleging breach of contract, fraud and regulatory violations. The corporation was contracted to establish and manage the clients’ in-house pathology laboratory, but failed to comply with the Clinical Laboratory Improvement Amendments (CLIA), Stark Law, the False Claims Act, the anti-markup rule and California’s False Claims Act. Obtained a favorable result for her client.
  • Independent Physician Association Reimbursement Dispute: Represented a large group of emergency physicians in litigation against an IPA to recover payment for services at physicians’ usual and customary rates. The Independent Physician Association (IPA) wrongly withheld several hundreds of thousands of dollars refusing to pay usual and customary rates for Current Procedural Terminology (CPT) codes as billed. Ms. Hagemann obtained a favorable settlement on the clients’ behalf, including payment of past amounts due, and structured agreed-upon contract rates going forward.
  • Professional Malpractice: Represented an attorney who was sued for malpractice, fraud, negligence and elder abuse following modifications he made to a decedent’s trust and pour-over will. The beneficiaries of testamentary documents challenged modifications and alleged a conspiracy between the client and another beneficiary.  Ms. Hagemann obtained a complete defense judgment for the client following a lengthy bench trial. The court found that the client practiced competently, the fraud and elder abuse claims were completely unfounded, and there was no conspiracy. 
  • Recoupment Requests and Audits: Represented numerous substance abuse treatment facilities in recoupment requests and audits from major payors.
  • Reimbursement Dispute: Represented emergency medical transportation providers in litigation challenging Medi-Cal reimbursement rates. The Department of Health Care Services set clients’ reimbursement rates without complying with federal and state requirements, and without considering clients’ costs to provide those services. 
  • Seven Figure Recoupment Request: Represented a urinalysis laboratory in a seven figure recoupment request, and favorably resolved the matter without litigation.
  • Substance Abuse Treatment Facility Compliance: Developed policies and procedures for substance abuse providers relating to marketing, referrals and payor relationships to ensure compliance with Federal and state regulations.

  • Substance Abuse Treatment Litigation: Represented provider in action brought by major insurer alleging illegal kickbacks in exchange for the referral of specimens to toxicology laboratory.

  • Substance Abuse Treatment Administrative Hearing: Represented detoxification facility in administrative action brought by the California Department of Health Care Services seeking revocation of client’s license.
