Heather Bassett

Dr. Heather Bassett has over 20 years’ experience in healthcare and has served as Chief Medical Officer for Xsolis since January 2013. She leads Xsolis’ team of physicians and partnered with its data science team to pioneer the Care Level Score (CLS), which combines clinical expertise and data science – artificial intelligence and machine learning – for a numerical representation indicating the appropriate care status for each patient.  

While working as a hospitalist at a large acute care facility in Nashville, Dr. Bassett experienced frustration with technology and excessive data entry that pulled her away from delivering care to her patients. She took this frustration and her long-standing interest in technology as an opportunity to improve healthcare operations for clinicians through data driven analytics, which has proved to be a valuable vantage point for a Chief Medical Officer. Dr. Bassett provides oversight of Xsolis’ data science team, denials management team and its physician advisor program, which has won No. 1 Best in KLAS Physician Advisory Services for five years, most recently in 2026. 

Dr. Bassett earned her B.S. in biological sciences from Carnegie Mellon University, Pittsburgh, Pa., and her Doctor of Medicine from the University of Texas Medical Branch, Galveston, Texas, where she worked as a research associate in the field of DNA repair. She undertook her residency in internal medicine at Vanderbilt University Medical Center and worked as a hospitalist at Centennial Medical Center in Nashville, Tenn., for eight years. She is board-certified in internal medicine.   

Dr. Bassett is passionate about advancing responsible AI in healthcare and is actively leading Xsolis’ involvement with the Coalition for Health AI (CHAI), an organization advancing the responsible development, deployment, and oversight of AI in healthcare, which Xsolis joined as an Early Member, in addition to serving on the NCQA Working Group on AI in Health Care. Dr. Bassett received a Gold Stevie® Award honoring her as the “Most Innovative Woman of the Year – Healthcare” in 2025, as Chief Medical Officer of the Year at the Nashville Business Journal’s Health Care Innovation Awards in 2021, and was named to Becker’s Hospital Review’s Women in Health IT to Know 2023-2025. She has contributed articles or been featured in Newsweek, Forbes, U.S. News & World Report, AARP Magazine, InformationWeek, Becker’s, Fierce Healthcare, Medical Economics, MedCity News, Physicians Practice, and Patient Safety Quality Healthcare. 

Dr. Bassett lives in Nashville with her husband, four-legged fur babies, and actively supports local charitable organizations including dog rescues and Gigi’s Playhouse, for which she led Xsolis’ participation in their Row for a Reason fundraiser. She enjoys traveling, hiking, outdoor adventures and cooking, and won a bronze medal in Olympic weightlifting in the 2015 Masters World Cup.
