What medical specialty does House M.D.’s character Remy Hadley practice?

Remy Hadley, known as Thirteen, practices internal medicine in House M.D. She joins Gregory House’s diagnostic team after the selection process for his new fellows.

Hadley is portrayed by Olivia Wilde and becomes one of the show’s recurring physicians. Her nickname comes from the number associated with her during the fellowship competition. The character is also notable for carrying the gene for Huntington’s disease, a progressive inherited neurological disorder, and for eventually developing symptoms connected to that risk.

Internal medicine is a broad adult-medicine specialty focused on diagnosing and treating complex illnesses. It is distinct from neurosurgery, which involves operations on the nervous system, and from cardiology, which focuses on the heart and circulatory system. Because Thirteen handles many rare and multisystem cases, viewers may associate her with neurology, but her stated specialty is internal medicine.
