What the code means

A physician who specializes in the treatment of obesity demonstrates competency in and a thorough understanding of the treatment of obesity and the genetic, biologic, environmental, social, and behavioral factors that contribute to obesity. The obesity medicine physician employs therapeutic interventions including diet, physical activity, behavioral change, and pharmacotherapy. The obesity medicine physician utilizes a comprehensive approach, and may include additional resources such as dietitians, exercise physiologists, mental health professionals and bariatric surgeons as indicated to achieve optimal results. Additionally, the obesity medicine physician maintains competency in providing pre- peri- and post-surgical care of bariatric surgery patients, promotes the prevention of obesity, and advocates for those who suffer from obesity.

Who registers under this code

138 of these are people and 189 are organisations, so 58% of the code is businesses rather than clinicians. Half of them had registered by 2014, and 85 registered in the last five years, 26% of the current population.

That is close to the pace of the registry as a whole.

Where the practices are

By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

Looking up a specific provider

These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
