What Obesity Medicine covers

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.

Full NPPES record

An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check

1699012302 passes the NPI check digit test The final digit 2 matches the value computed from the first nine digits, so this is a well-formed NPI.
How the check works, step by step

Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.

Digit 8 0 8 4 0 1 6 9 9 0 1 2 3 0
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 6 9 9 0 1 4 3 0

Sum = 58 · next multiple of 10 = 60 · check digit = 2 · actual last digit = 2

A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
