Weight Management is Moving into the Workplace and Mainstream of Healthcare
bull Screening for Obesity in Adults The US Preventive Services Task Force recommends that clinicians screen all adult patients for obesity and offer intensive counseling and behavioral interventions to promote sustained weight loss for obese adults (Grade B recommendation)
bull Medicare now covers behavioral treatment of obesity
US Preventive Services Task Force Ann Intern Med 2003139930‐932
US Preventative Services Task Force
bull The USPSTF found that the most effective interventions were comprehensive and were of high intensity (12 to 26 sessions in a year)
bull Multiple behavioral management activities such as group sessions individual sessions setting weight-loss goals improving diet or nutrition physical activity sessions addressing barriers to change active use of self-monitoring and strategizing how to maintain lifestyle changes
bull A weight loss of 5 is considered clinically important by the US Food and Drug Administration (FDA)

A Proposal from CMS about Coverage for Intensive Behavioral Therapy for Obesity
bull For obese Medicare beneficiaries whose counseling is furnished by a qualified primary care physician or other primary care practitioner and in a primary care setting the CMS proposes coverage of
bull One face-to-face visit every week for the first month bull One face-to-face visit every other week for months 2 to 6 and bull One face-to-face visit every month for months 7 to 12bull At the 6-month visit a reassessment of obesity and a
determination of the amount of weight loss should be performed To be eligible for face-to-face visits occurring once a month for an additional 6 months beneficiaries must have achieved a reduction in weight of at least 3 kg during the course of the first 6 months of intensive therapy

Weight Management is Moving into the Workplace and Mainstream of Healthcare
bull Screening for Obesity in Adults The US Preventive Services Task Force recommends that clinicians screen all adult patients for obesity and offer intensive counseling and behavioral interventions to promote sustained weight loss for obese adults (Grade B recommendation)
bull Medicare now covers behavioral treatment of obesity
US Preventive Services Task Force Ann Intern Med 2003139930‐932
US Preventative Services Task Force
bull The USPSTF found that the most effective interventions were comprehensive and were of high intensity (12 to 26 sessions in a year)
bull Multiple behavioral management activities such as group sessions individual sessions setting weight-loss goals improving diet or nutrition physical activity sessions addressing barriers to change active use of self-monitoring and strategizing how to maintain lifestyle changes
bull A weight loss of 5 is considered clinically important by the US Food and Drug Administration (FDA)
httpwwwuspreventiveservicestaskforceorguspstf11obeseadultobesershtmAnn Intern Med 201226 June
A Proposal from CMS about Coverage for Intensive Behavioral Therapy for Obesity
bull For obese Medicare beneficiaries whose counseling is furnished by a qualified primary care physician or other primary care practitioner and in a primary care setting the CMS proposes coverage of
bull One face-to-face visit every week for the first month bull One face-to-face visit every other week for months 2 to 6 and bull One face-to-face visit every month for months 7 to 12bull At the 6-month visit a reassessment of obesity and a
determination of the amount of weight loss should be performed To be eligible for face-to-face visits occurring once a month for an additional 6 months beneficiaries must have achieved a reduction in weight of at least 3 kg during the course of the first 6 months of intensive therapy

US Preventative Services Task Force
bull The USPSTF found that the most effective interventions were comprehensive and were of high intensity (12 to 26 sessions in a year)
bull Multiple behavioral management activities such as group sessions individual sessions setting weight-loss goals improving diet or nutrition physical activity sessions addressing barriers to change active use of self-monitoring and strategizing how to maintain lifestyle changes
bull A weight loss of 5 is considered clinically important by the US Food and Drug Administration (FDA)

A Proposal from CMS about Coverage for Intensive Behavioral Therapy for Obesity
bull For obese Medicare beneficiaries whose counseling is furnished by a qualified primary care physician or other primary care practitioner and in a primary care setting the CMS proposes coverage of
bull One face-to-face visit every week for the first month bull One face-to-face visit every other week for months 2 to 6 and bull One face-to-face visit every month for months 7 to 12bull At the 6-month visit a reassessment of obesity and a
determination of the amount of weight loss should be performed To be eligible for face-to-face visits occurring once a month for an additional 6 months beneficiaries must have achieved a reduction in weight of at least 3 kg during the course of the first 6 months of intensive therapy

A Proposal from CMS about Coverage for Intensive Behavioral Therapy for Obesity
bull For obese Medicare beneficiaries whose counseling is furnished by a qualified primary care physician or other primary care practitioner and in a primary care setting the CMS proposes coverage of
bull One face-to-face visit every week for the first month bull One face-to-face visit every other week for months 2 to 6 and bull One face-to-face visit every month for months 7 to 12bull At the 6-month visit a reassessment of obesity and a
determination of the amount of weight loss should be performed To be eligible for face-to-face visits occurring once a month for an additional 6 months beneficiaries must have achieved a reduction in weight of at least 3 kg during the course of the first 6 months of intensive therapy
