OBJECTIVES:  To compare Medicare Advantage beneficiary population health status for patients utilizing provider services solely with narrow networks (NN) which are plans with relatively low copays and premiums, but where provider options are considerably constrained, or with Patient Centered Medical Home (PCMH) providers. METHODS:  This retrospective cohort study used data from Strenuus, a managed care data aggregator, to identify providers participating in NN and PCMH product. Five insurers were selected based on size and variety of products, and their NN and PCMH product were identified. The patient population of Medicare Advantage (MA) members was extracted from a large nationally representative and statistically de-identified administrative claims database. Members were divided into three groups based on their provider: 1) members receiving services solely within a NN/PCMH (“In”); 2) members receiving services solely outside NN/PCMH (“Out”); and 3) members receiving services both in and outside of NN/PCMH (“Control”). CMS-HCC Risk Scores (version 22) were calculated for each member. The study sample consisted of MA beneficiaries who were continuously enrolled for 12 months within 2014 (N=1.4 million) and in 2015 (N=1.1 million). RESULTS: The distribution of members across the groups (In, Out and Control,) was 40%, 10% and 51%, respectively, and was consistent across years. In 2014, mean risk score (and standard deviation) for In, Out and Control, groups respectively were: 0.78 (0.56), .88 (.70), and 1.18 (.98). Similarly, in 2015, these results were 0.88 (0.51), 1.18 (0.70) and 1.44 (0.88). The mean risk scores across the three groups within each year were significantly different (p < .01). CONCLUSIONS:  Data suggest that beneficiaries receiving all of their care from NN/PCMH providers are healthier than those entirely outside NN/PCMH. Further, beneficiaries receiving a mix of in- and out-network are the least healthy of the three groups.
