Introduction

Joshua A. Ronen, MD, FACP is an actively practicing, board-certified internal medicine physician whose clinical practice centers on hospitalized adults. He works as a direct care hospitalist at Huntington Hospital in Pasadena, California, carrying an inpatient census of up to 15–20 patients on daytime rounds, admitting from the emergency department, and making escalation, consultation and discharge decisions. During his first five years of attending practice, 50–75% of his work was night coverage, with up to 10 admissions a night.

Alongside clinical practice he serves as a Physician Advisor to Utilization Management. In that role he works with hospital leadership and multidisciplinary teams on medical necessity determinations, inpatient versus observation status, documentation adequacy and compliance, and the appropriate use of inpatient resources. Most hospitalist experts can speak to what a physician should have done clinically; comparatively few can also speak to how status, necessity and documentation decisions are actually made inside a hospital, and to the standards those decisions are measured against.

Dr. Ronen earned his medical degree from Ross University School of Medicine and completed internal medicine residency at Texas Tech University Health Sciences Center at the Permian Basin. He began his attending career with a faculty appointment at UCSF Medical Center, most recently as Assistant Professor of Clinical Medicine (2021–2023), practicing as a hospitalist with a largely nocturnal service while teaching medical students and residents. He is a Fellow of the American College of Physicians and the author of eleven PubMed-indexed peer-reviewed publications.

Through his professional corporation, and independently of Huntington Hospital, Dr. Ronen provides expert medical review in medical malpractice, personal injury and wrongful death matters involving hospital-based internal medicine: case screening, medical record review, standard-of-care evaluation, causation analysis, written expert opinions, and deposition and trial testimony. He accepts engagements from attorneys and law firms only, for plaintiff and defense alike, and only in matters within his expertise. He does not accept matters involving institutions where he practices.

He is based in Southern California and available to counsel nationwide, will travel for deposition or trial, and offers remote deposition where the parties agree. A complimentary 10-minute phone consultation at (323) 682-0039 and a conflict check precede any formal engagement. Inquiries are answered within 24 hours.
