4. Weight First Initiative The Endocrine Society engaged four health care practitioners -- an internist, a family practice physician, an osteopathic practitioner, and a nurse practitioner -- in a pilot program to collaborate with faculty on the Guidelines on Pharmacologic Management of Obesity to develop a curriculum for primary care practitioners in obesity medical management best practices. The objective of the Weight First initiative 2016 pilot is to demonstrate that an obesity curriculum co-developed by endocrinologists and primary care practitioners overcomes barriers to the effective management of patients with obesity. The goal was to encourage primary care practitioners to treat weight first, rather than treating co-morbidities without directly addressing weight as a factor in overall health.

Obesity as an endocrine-related disease American Medical Association (AMA) recognizes obesity as a disease: It is a multi-metabolic and hormonal disease state It has characteristic signs and symptoms Increase in fat mass associated with obesity is directly related to comorbidities such as type 2 diabetes mellitus, cardiovascular disease, and cancer Disease results through a perturbation in the central nervous system (CNS) regulation of energy homeostasis Under normal conditions, food intake and energy expenditure are balanced by a homeostatic system that maintains stability of body fat content over time. Obesity results through a perturbation in CNS regulation of energy homeostasis.

22. Summary (Risks of overweight & obesity, Benefits of weight modest weight loss) Obesity is associated with an increased risk for coronary heart disease, type 2 diabetes, various types of cancer, gallstones, and disability. Obesity is associated with an increased risk for death, particularly in adults younger than 65 years. The risk of disease increases with BMI and waist circumference. Weight loss as little as 3% - 5% in obese individuals is associated with a lower incidence of health problems and death.

23. Obesity is a disease, but are we talking about it? USPSTF recommends screening all adults for obesity yet: A third of patients with a BMI ≥ 30 were never told by their doctors that they have obesity Rates of physician counseling appear to be decreasing, by as much as 25 percent. Those rates are worse for patients with obesity co-morbidities Health care provider – patient conversations about nutrition last an average of 55 seconds Intensive behavioral counseling can induce clinically meaningful weight loss, but there is little research on primary care practitioners providing such care Post RE et al.

24. STEP 1: Talk to patients about obesity Motivational interviewing and shared decision-making with patients

25. Meet Rosalia: Working mom with a family history of type 2 diabetes In for annual visit. 49-year-old office manager for Blue Cross, recently promoted, divorced, 2 children Does not smoke or drink Took paroxetine around time of divorce for depression – continues on it. Her father has T2DM and is on dialysis; She says “I know this runs in families and I don’t want it to happen to me. Meds: Has been on paroxetine since her divorce 4 years ago, asymptomatic. Workup Height: 5’8”; weight: 223 lbs; BMI: 34 kg/m 2 (comments: “I need to lose at least 80 pounds”) BP: 130/80 mm; pulse: 70 bpm, Resp: WNL Mammogram report: normal Lab Chem Survey: glucose 107, A1c 5.8%, otherwise normal. Cholesterol 238, HDL 64, TG 124, LDL 149. CBC & UA normal. TSH 3.91. Pap smear normal.

26. How do you think about your patients’ weight struggles? What you might think: She needs to lose at least 80 pounds. I need to start her on metformin, advise her to lose weight and see her back in a year. She can lose weight by just eating a bit less and exercising a bit more. I will tell her about healthy lifestyle. If she struggles, she just needs more resolve. She doesn’t need medications. She can do this on her own. The reality: She can greatly reduce her risk for diabetes with loss of just 11 - 22 pounds. She can improve risk for diabetes, BP, and lipids with weight loss. This needs to be the first and central approach. Weight loss requires skills training. The more intensive the coaching, the greater the chance of meaningful weight loss. Some of her medications caused her to gain weight. She may need help with medications both to lose weight and to address biologic adaptations to weight loss.

27. The 5As of Obesity Management Vallis M, et al. Can Fam Physician. 2013;59:27-31; ​ Meriwether RA, et al. Am Fam Physician. 2008;77(8):1129-3. Ask Ask for permission to discuss weight Explore readiness for change Assess Assess obesity class and stage Assess for drivers (root cause), complications, and barriers Advise Advise on obesity risks (related more to obesity stage than BMI) Explain benefits of modest weight loss focusing on improving health & wellbeing Explain need for long-term strategy Discuss treatment options Agree Agree on realistic weight-loss expectations Agree on treatment plan Assist Address drivers and barriers Provide education and resources Refer to appropriate provider Arrange follow-up

28. Talk to Rosalia using the 5 As of obesity management Ask: “Let’s talk about your exam. Your mammogram is normal and your exam and most of your tests are fine. But your blood sugar and A1c are higher than we like to see. This is pre- diabetes. The single best thing you could do for your health would be to make some lifestyle changes that produce some weight loss. Is today a good time to talk about your weight?” Rosalia: “Yes, we can talk about it. I know I need to lose weight – at least 80 pounds. I don’t want to end up like my father.” You: I’m glad to hear you are taking this seriously. We can talk about a goal later, but the good news is that you can improve your diabetes risk with 11-22 pounds loss. Let me ask you a few questions to get started.” What if she says, “No”? Assess: Comorbidities (sleep apnea symptoms, depression symptoms) Drivers of weight gain (medications including OTC; sleep deprivation, stress) Complications and Barriers to weight loss success. Current lifestyle. What has worked in the past. What hasn’t worked in the past.

29. Motivational interviewing (OARS Strategy) O Open-ended questions Ask open-ended questions that encourage thought- provoking response Engage in a 2-way dialogue Goal is to understand a patient’s barriers and expectations S Summary statements Use statements that recount and clarify the patient’s statements Identify specific points to act upon A Affirmative statements Recognize and support the patient’s personal strengths, successes, and efforts to change Goal is to promote a collaborative relationship R Reflections Use reflective listening Respond thoughtfully by paraphrasing Confirm that the patient has been heard Validate the patient’s point of view

30. Talk with Rosalia using OARS motivational interviewing strategy Clinician (you): You mentioned 80 pounds, but losing 11-22 pounds and even as little as 8 pounds can reduce your risk. How do you feel about that statement? Or, “What are some of your thoughts on losing weight?" Health is the right reason to make lifestyle changes. You CAN decrease your diabetes risk. Regaining weight is the result of our bodies’ natural defenses. It’s not your fault. It sounds like you are saying you need some help with maintaining lost weight. What do you think about that? That’s one option we can discuss for our long term strategy. I’m hearing that you’ve struggled with weight and recognize how it is affecting your health and quality of life. Ok. Now, let’s discuss some strategies to develop a long-term plan to help you address your concerns Rosalia: I know I can do it because I have done it before. With Weight Watchers online once. I lost 10 pounds in 3 months. I also did Jenny Craig with even more weight loss. I know I will never be skinny, but I want to be healthy and be around for my kids. Yes, but I can’t keep it off, so I wasn’t successful. Yes. I don’t think I can do it without help. I might need something. What about medication? OK!

48. Developing a treatment plan for Rosalia Advising on treatment options You advise Rosalia that losing at least 5% of weight loss in the next 12 weeks is, for now, a good goal. You reviewed medications and other drivers of weight gain (acetominophen PM, paroxetine). Rosalia asked about weight-loss medication and you discussed the available options. Agreeing on weight goals and treatment plan Rosalia will attend weekly Weight Watchers meetings because her office wellness program offers it. Instead of eating at her desk, Rosalia will join co-workers on lunchtime walks. She sets a goal of 150 minutes per week of brisk walking. Rosalia will adopt a low-glycemic index diet in the Weight Watchers program after a visit with a dietitian. Together, you make a decision to taper and discontinue paroxetine and to discontinue acetaminophen PM. Rosalia will monitor sleep duration on her Fitbit and has engaged in meditation through a smartphone app. Rosalia begins liraglutide 0.6 mg with a dose escalation planned to 3.0 mg Follow-up plan Refer her to a local dietician you’ve worked with in the past Schedule follow-up visits weekly for the next 3 weeks, then monthly for the next 3 months Check in at 12 weeks to confirm if she’s lost at least 5% of her weight Follow at least every three months thereafter. After 6 months, renew emphasis on physical activity, trying to push to 250 minutes of moderate activity per week. Continue liraglutide.

56. Putting it all together: Obesity is a complex, chronic disease Risk for obesity is driven by environmental and biologic factors in genetically susceptible individuals Moderate weight loss can improve health, but response to treatment is highly variable and weight regain is common When patients struggle, intensification of approach is appropriate Combinations of approaches (diet, exercise, drugs, devices and surgery) produce more weight loss and health benefit

57. STEP 3: Get reimbursed Reimbursement for Obesity Management

58. Key Considerations Centers for Medicare and Medicaid Services Reimbursement of IBT for obesity Obesity is a disease and should be treated like one. If you can’t treat it like a disease, treat comorbid conditions, billed using E&M codes. Medicare Part B allows reimbursement for IBT for obesity w/some restrictions for: screening for obesity in adults using BMI; dietary (nutritional) assessment; and, intensive behavioral counseling and therapy to promote sustained weight loss through high-intensity interventions on diet and exercise. Medicare coinsurance and Part B deductible are waived. Private insurance coverage of IBT for obesity remains highly variable However, because Medicare policy exerts a major influence on the commercial health care system, which often adopts its reimbursement and coverage policies.

59. U.S. Department of Health and Human Services. Intensive Behavioral Therapy (IBT) for Obesity. Centers for Medicare & Medicaid Services, August 2012 Requirements for Medicare coverage Eligible beneficiaries Qualified primary care providers Allowable visits Allowable primary care settings BMI>30kg/m2 Competent and alert when counseling is provided Must lose 3kg (6.6lbs) during the first 6 months for continuing coverage A physician who has a primary specialty designation of family practice, general practice, geriatric medicine, internal medicine, OB/GYN, or pediatric medicine A qualified non-physician practitioner who is a certified clinical nurse specialist, nurse practitioner, or physician assistant Auxiliary personnel such as registered dieticians working for one of the provider specialty types listed above 22 IBT sessions for obesity is maximum in a 12-month period 1 face-to-face visit every week for first month 1 face-to-face visit every other week for months 2-6 1 face-to-face visit every month for months 7-12 if beneficiary loses at least 3kg (6.6lbs) during first 6 months Independent clinics Outpatient clinics Physician’s offices State or local public health clinics

60. Medical records must document all coverage requirements, including the determination of weight loss at the 6- month visit Must document treatment consistent with the 5A’s approach Stand Alone Benefit: The IBT for obesity covered by Medicare is a stand alone billable service separate from the initial preventive physical exam (IPPE) or the Annual Wellness Visit (AMV). Medicare beneficiaries may obtain IBT for obesity services at any time following Medicare Part B enrollment, including during IPPE or AMV encounter. Note: Obesity counseling is not separately payable with another visit on the same day with the exception initial physical exams, diabetes self-management and medical nutrition therapy services (code 77X), and distinct procedural services claims (modifier 59) CMS. MLN Matters MM7641. 2012. Documentation for IBT for obesity

61. Billing and coding requirements for IBT Submitting Professional Claims Report the appropriate HCPCS code and the corresponding ICD-10-CM diagnosis code in the X12 837-P (Professional) electronic claim format Include Place of Service (POS) codes to indicate where service was provided ASCA requires providers to submit claims to Medicare electronically, with limited exceptions Submitting Institutional Claims Report the appropriate HCPCS code, revenue code, and the corresponding ICD-10-CM diagnosis code in the Xl 2 837-1 (Institutional) electronic claim format Types of Bill (TOBs) Allowed for Institutional Claims: hospital outpatient, rural health clinic (RHC), federally qualitied health center (FQHC), critical access hospital (CAH) Coding and Diagnosis Information Use the Healthcare Common Procedure Coding System (HCPCS code) G0447 (face-to-face behavioral counseling for obesity) and relevant ICD- 10-DM Diagnosis Code for BMI 30.0 and over (Z68.30-Z68.39, Z68.41-Z68.45) Do not use E66.01 or E66.09 No need to add comorbid diagnoses Use preventative codes 99401-99404 mandated by ACA for follow-up and management Covered IBT can be provided “incident to” i.e., by auxiliary staff member such as NP or PA under direct supervision of physician Can be an efficient and cost-effective way to provide IBT for obesity in a busy practice setting Physicians of other specialties may be compensated for IBT if they have multiple credentials and bill under approved taxonomy codes – e.g., NP or PA Centers for Medicare and Medicaid Services

62. Payment information U.S. Department of Health and Human Services. Intensive Behavioral Therapy (IBT) for Obesity. Centers for Medicare & Medicaid Services, August 2012 Professional Claims Medicare pays for IBT for obesity under the Medicare Physician Fee Schedule (MPFS). As with other MPFS services, non-participating provider reduction and limiting charge provisions apply to all IBT for obesity services Institutional Claims Facility type (hospital outpatient, RHC, FQHC, or CAH) determines Medicare payment for IBT for obesity Facility Payment Methods for IBT for Obesity Hospital Outpatient: Outpatient Prospective Payment System (OPPS) RHC: All-Inclusive Payment Rate FQHC: All-Inclusive Payment Rate CAH: Method I: 101% of reasonable cost for technical component(s) of services or Method II: 101% of reasonable cost for technical component(s) of services, plus 114% of MPFS non-facility rate for professional component(s) of services Reasons for Claim Denial may include: The beneficiary got more than 22 IBT for obesity sessions in the last 12 months. The beneficiary got IBT for obesity outside of the primary care setting.
