Introduction
Health-related social needs (HRSNs), such as housing instability and food insecurity, are unmet nonclinical needs that can adversely affect patients’ ability to maintain health and well-being but, if addressed, can promote better outcomes.^1,2^ In 2024, Medicare began reimbursing clinicians for HRSN-related activities, including social determinants of health (SDOH) risk assessment, community health integration (CHI), and principal illness navigation (PIN).^3^ Although prior work evaluated HRSN services, this study aimed to examine their early utilization and reimbursement in Medicare.
Methods
We used 2024 Medicare data encompassing 100% of professional services billed to and reimbursed by traditional Medicare.^4^ The University of Texas Southwestern Medical Center IRB deemed this cross-sectional study exempt from review and informed consent because it was not human participant research. We followed the STROBE reporting guideline.
Healthcare Common Procedure Coding System codes were used to capture SDOH risk assessment (code G0136), which must involve standardized, evidence-based tools that at a minimum assess for food or housing insecurity, transportation needs, and utility difficulties; CHI (codes G0019, G0022), which includes facilitating access to community-based resources, home- and community-based care coordination, and patient self-advocacy promotion; and PIN (codes G0023, G0024, G0140, G0146), which supports patients with serious, high-risk conditions expected to last at least 3 months and put patients at substantial risk of functional decline, death, or acute care utilization.
We assessed services submitted to and reimbursed or denied by Medicare. Utilization was stratified by specialty type and place of service. Specialty type included physician grouping (primary care [eg, family practice, internal medicine], medical subspecialty [eg, cardiology, oncology], and other specialty [eg, surgery]) and nonphysician grouping (advanced practice professional [eg, nurse practitioner, physician assistant] and other [eg, licensed clinical social worker]).^5^ Place of service was categorized as physician office, outpatient hospital, inpatient hospital, and other setting (eg, skilled nursing facility).
Results
In 2024, 285 270 HRSN-related services were delivered across the US. Of those, 208 819 services (73.2%) were reimbursed through $5 007 978 in aggregate payments (Table 1). SDOH risk assessment services were most frequently delivered (82.7% [235 974]), followed by CHI (14.5% [41 362]) and PIN services (2.8% [7934]).
Most HRSN-related services were reimbursed: 73.0% (172 330) of SDOH risk assessment services, corresponding to 1 709 693 in payments; and 85.4% (6777) of PIN services, corresponding to $440 168 in payments. Of the services delivered, 26.8% (76 451) were denied and not reimbursed.
HRSN-related services were most commonly performed by primary care physicians (75.4% [215 014]), followed by advanced practice professionals (19.0% [54 372]). The minority of services were performed by medical subspecialists (3.7% [10 486]), other specialists (1.3% [3702]), and nonphysicians (0.6% [1696]) (Table 2). Most services were delivered in physician offices (87.7% [250 228]) compared with other settings (6.2% [17 741]), outpatient hospitals (3.8% [10 882]), and inpatient hospitals (2.3% [6419]).
Discussion
In the first year Medicare reimbursed HRSN-related services, adoption was limited to the 34 million beneficiaries of traditional Medicare.^6^ Services were predominantly offered by primary care physicians in office settings, with a notable proportion of delivered services being denied by and not receiving reimbursement from Medicare. These findings highlight the critical role of primary care in supporting patients with HRSNs and the barriers to providing HRSN-related services, including misaligned infrastructure, staffing, and workflows. Denied payments also underscore that documentation requirements or other administrative burdens potentially impede adoption. Future work can identify and test interventions for reducing barriers to providing and accessing HRSN-related services.
Study limitations include the descriptive cross-sectional design and lack of practice- and patient-level data, precluding us from discussing causality of denied claims. HRSN-related services may also be coordinated outside of traditional Medicare through Medicare Advantage or state programs, especially for patients dually eligible for Medicare and Medicaid. Nonetheless, this study provides new insight into early adoption of HRSN-related services in Medicare, offering early evidence that may spur research and policy.
