A survey of primary care practices on their use of the intensive behavioral therapy for obese Medicare patients.
The objective of this study was to fill the gap in knowledge on systematic differences between primary care practices (PCP) that do or do not provide intensive behavioral therapy (IBT) for obese Medicare patients. The investigators concluded that although the Centers for Medicare and Medicaid Services established payment codes for PCPs to deliver IBT for obesity in 2011, very few providers submitted fee-for-service claims for these services after almost 10 years.

The joys and challenges of delivering obesity care: a qualitative study of US primary care practices.
The authors sought to explore the experience of providing obesity management among primary care clinicians and their team members involved with weight loss in primary care practices. They identified three primary themes: (1) clinicians and staff involved in obesity management in primary care believe that addressing obesity is an essential part of primary care services, (2) because providing obesity care can be challenging, many practices opt out of treatment, and (3) despite the challenges, many clinicians and others find treating obesity feasible, satisfying, and worthwhile. The authors concluded that, in order to improve the ability of clinicians and practice members to treat obesity, important changes in payment, education, and work processes are necessary.

Payment discrepancies and access to primary care physicians for dual-eligible Medicare-Medicaid beneficiaries.
This study examined whether the Affordable Care Act (ACA) primary care fee bump for dual-eligible Medicare-Medicaid beneficiaries impacted primary care physicians (PCP) acceptance of duals. The authors assessed differences in the likelihood that PCPs had dual caseloads of ≥10% or 20% in states with lower versus full dual reimbursement using linear probability models adjusted for physician and area-level traits. The proportion of PCPs with dual caseloads of ≥10% or 20% decreased significantly between 2012 and 2017. The fee bump was not consistently associated with increases in dual caseloads.

Higher Medicare spending on imaging and lab services after primary care physician group vertical integration.
This study looked at the impact of direct ownership of physician practices by hospitals and health systems (vertical integration) on Medicare spending for imaging and lab services. A 100% sample of 2013-16 Medicare fee-for-service claims data was examined to determine if vertical integration was associated with changes in site of care and Medicare reimbursement rates for ten common diagnostic imaging and laboratory services. After vertical integration, the monthly number of diagnostic imaging tests per 1,000 attributed beneficiaries increased in a hospital setting by 26.3 per 1000, and the number performed in a nonhospital setting decreased by 24.8 per 1,000. Hospital-based laboratory tests increased by 44.5 per 1,000 and non-hospital-based laboratory tests decreased by 36.0 per 1,000. Average Medicare reimbursement rose by $6.38 for imaging tests and $0.57 for laboratory tests. This translates to $40.2 million increase for imaging and $32.9 million increase for laboratory tests in Medicare spending for the study period.

How to identify team-based primary care in the United States using Medicare data.
The authors assessed whether analyses using different sets of Medicare data can produce results similar to those from analyses using 100% data from an entire state in identifying primary care teams through social network analysis. They found that, depending on specific study purposes, researchers could use either 100% data from Medicare beneficiaries in randomly selected primary care services areas or data from a 20% national sample of Medicare beneficiaries to study team-based primary care in the United States.
