What is House's medical degree in House M.D.?

House's medical degree in House M.D. is a Doctor of Medicine, commonly abbreviated M.D. The credential is reflected in the character's title, Dr. Gregory House, and in his work as a licensed physician and diagnostician.

The series presents House as a physician trained in both conventional medical practice and diagnostic reasoning. His specialty is not limited to one organ system: he leads a department that evaluates unusual cases requiring broad knowledge, testing, and consultation with other specialists.

The M.D. abbreviation is also part of the show's title, distinguishing the program from a general drama about a character named House. In the United States, a Doctor of Medicine degree is a professional medical degree, while D.O. identifies a Doctor of Osteopathic Medicine.

Other doctorates can sound plausible in a hospital setting, including pharmacy or dental degrees, but they do not describe House's qualification. House is a physician who diagnoses and treats patients, not a dentist or pharmacist.
