Litigation and Dispute Resolution
Litigation and Dispute Resolution
Kathryn represents healthcare providers, primarily in disputes with the California Department of Health Care Services or private commercial payors relating to reimbursement for healthcare services. Her approach emphasizes identifying client objectives and implementing the most cost-effective strategy to best achieve those goals.

With more than 20 years of experience as a litigator, coupled with extensive knowledge of the healthcare industry and its governing statutes, regulations, and agencies, Kathryn brings a wide range of experience and problem-solving skills to address her clients’ needs. Kathryn works successfully with clients to identify and employ a winning strategy to resolve disputes and optimize outcomes, whether that involves arranging meetings with state agencies or payors, drafting position papers, negotiating contracts or settlements, or arbitrating or litigating disputes.

Kathryn represents exclusively healthcare providers and affiliated organizations, including trade associations, health systems, hospitals, community health clinics, Federally-qualified health centers, rural health clinics, ambulatory surgery centers, residential care facilities for the elderly, skilled nursing facilities, physician groups, physicians, and air ambulance companies.

Kathryn has served in the highest ranks of state government for the State of California, including as Senior Deputy Legal Affairs Secretary for Governor Gray Davis. In September 2013, Governor Jerry Brown appointed Kathryn as a public member of the California New Motor Vehicle Board and reappointed her in March 2017; she was re-appointed by Governor Gavin Newsom in January 2021. She is the designated attorney appointment, and was elected to serve as President of the Board for calendar years 2019 and 2020, after serving as Vice President in 2017 and 2018. Prior to her government service, Kathryn worked in private practice and clerked for a federal judge.

Representative Work

When the California Department of Health Care Services (“DHCS”) stopped reimbursing Medi-Cal providers for adult dental, podiatry, and chiropractic services, Kathryn was the lead attorney in successful federal court litigation to challenge the elimination of these benefits when provided by rural health clinics and Federally qualified health centers. (California Association of Rural Health Clinics v. Douglas (9th Cir. 2013) 738 F.3d 1007.) In connection with this lawsuit, Kathryn and her co-counsel brought a petition for a writ of mandate to successfully compel production of the DHCS documents in response to a request under the California Public Records Act. In October 2013, Kathryn and her co-counsel received the “Hero Award” from the California Primary Care Association for these efforts.

When workers compensation insurers reduced their payments to air ambulance companies based on the California Official Medical Fee Schedule, Kathryn represented an air ambulance company in a federal court challenge to the imposition of the fee schedule on air ambulance companies on the grounds the preemption provision of the federal Airline Deregulation Act prevents the State from regulating the prices of air ambulances under the Supremacy Clause. (California Shock Trauma Air Rescue v. State Compensation Ins. Fund (9th Cir. 2011) 636 F.3d 538.) When the Ninth Circuit concluded that it lacked the authority to hear the dispute, Kathryn represented the air ambulance company in rulemaking proceedings that resulted in an exemption for air ambulance companies from the fee schedule. (See Cal. Code of Regs., tit. 8, § 9789.70(c).) Kathryn and her team have since brought hundreds of lien claims before the Workers’ Compensation Appeals Board, which has resulted in the additional payment of millions of dollars for her air ambulance clients.

Kathryn has also successfully represented hospitals in disputes with commercial health plans over the proper interpretation of provisions of the parties’ managed care contracts. Some of these disputes have resulted in settlements, others have been resolved through arbitration proceedings.

Kathryn has also successfully represented individual community health clinics and other providers in a variety of disputes with DHCS over reimbursement or provider enrollment issues. Resolution of these disputes has been achieved through meetings with the department, correspondence with the department, or administrative proceedings.

Kathryn also represents medical groups in negotiations with hospitals for professional services agreements and advises providers on 340B, right to fair procedure, medical records disclosure, HIPAA, Stark, corporate practice of medicine, and other healthcare laws.
