Abstract
Medically tailored meals (MTMs) can reduce health care use among high-risk patients with diet-related conditions. However, the potential impact of providing coverage for MTMs across fifty US states remains unknown. Using a population-based, open-cohort simulation model, we estimated state-specific one-year and five-year changes in annual hospitalizations, health care spending, and cost-effectiveness of MTMs for patients with diet-related diseases and limitations in activities of daily living, covered by Medicaid, Medicare, or private insurance. Assuming full uptake among eligible people, MTMs were net cost saving in the first year in forty-nine states, with the largest savings seen in Connecticut ($6,299 per patient). The exception was Alabama, where MTMs were cost-neutral. The number of treated patients needed to avert one hospitalization ranged from 2.3 (Maryland) to 6.9 (Colorado). These findings can inform state-level policy makers and health plans considering MTM coverage through state-specific strategies.
Poor diet is a leading determinant of disease burdens and health inequities.1 Medically tailored meals (MTMs) are a “Food Is Medicine” intervention that can improve diet-related health outcomes, reduce financial strain and improve associated well-being, address disparities, and reduce health care spending.2–4 MTMs are prepared, home-delivered meals, typically provided to people with complex health conditions and high acuity of care based on a referral from a medical professional or health plan. Registered dietitian nutritionists design MTMs on the basis of patients’ nutritional assessments and diagnoses. Existing MTM programs typically provide ten weekly meals for an average of eight months annually.5 Recipients often have comorbidities, limitations in instrumental activities of daily living (IADLs), nutritional risk, and high prior health care use.6
Research suggests that nationwide adoption of MTMs for patients with diet-sensitive conditions could reduce patients’ health care use and spending by public and private payers.6 However, MTM coverage remains limited, although several states are beginning to cover Food Is Medicine interventions through Medicaid demonstration projects.1,7 These states are important incubators for health care innovation.
US states vary considerably in demographics, disease prevalence, and health care use and spending, which may influence MTMs’ impact and cost-effectiveness. The impact of MTM coverage on health care use and spending by US state remains unknown. This study investigated the one-year and five-year effects of implementing MTMs in US states on hospitalizations, health care expenditures, and net costs among patients with diet-related diseases and ADL limitations under Medicaid, Medicare, and private insurance. By providing state-specific estimates, this analysis offers policy makers and health plans insights to guide MTM implementation decisions at the state level.
Study Data And Methods
Design, Setting, And Population
Adopting a previously published population-level, open-cohort policy simulation model,6 we estimated changes in annual hospitalizations and health care expenditures after the implementation of MTMs versus the status quo. The study sample combined 2010–19 data from the Medical Expenditure Panel Survey (MEPS).8 We excluded 2020 because of pandemic-related data collection changes.9 State-level restricted data were obtained from the Agency for Healthcare Research and Quality Data Center.10 Because MEPS state-specific data were only available for the twenty-nine most populous states, we estimated the size of the state-specific eligible populations using data from the 2019 Behavioral Risk Factor Surveillance System (see supplement table 1 in the online appendix).11 We could not jointly stratify results by both state and payer because of the diminishing size of the data on the eligible populations within these subgroups.
Patient Eligibility
The analytic sample included US adults older than age eighteen with Medicare, Medicaid, or private coverage who had one or more diet-sensitive conditions and IADL limitations. Diet-sensitive conditions include diabetes, coronary heart disease, myocardial infarction, other heart disease, emphysema, stroke, nonmelanoma cancer, chronic kidney disease, and HIV. We selected conditions based on previous MTM research.3,12–16 IADL limitations include receiving help using the telephone, paying bills, taking medications, preparing meals, doing laundry, or going shopping.17
MTM Intervention And Effect Sizes
We modeled the impact of providing ten weekly MTMs for a mean of eight months,6 following Food is Medicine Coalition standards.18 Effect sizes were estimated via an inverse-variance weighted meta-analysis of eight published interventional studies on MTM provision,3,12–14,19–22 all of which employed quasi-experimental controls. The analysis suggested that MTM provision was associated with a 47 percent reduction in annual hospitalizations (95% confidence interval: 36.1, 57.9) and a 19.7 percent reduction in annual health care expenditures (95% CI: 7.0, 32.4).
Intervention And Health Care Costs
Annual MTM program costs included clinical screening and program expenses. Screening expenses were based on 2024 Medicare reimbursement rates for a fifteen-minute medical nutritional therapy session with a registered dietitian, ranging from $33.50 (Mississippi) to $46.45 (Alaska).23 A 2024 survey of MTM organizations within the Food is Medicine Coalition (six responses) estimated that the mean program expense per meal was $11.15 (standard deviation: 1.71) (Alyssa Wassung, Food is Medicine Coalition, personal communication, May 22, 2024). The MTM meal costs represent fully burdened MTM-related expenditures, including labor; overhead; contracting; and direct expenses such as materials (food and packaging) and delivery.
We estimated state-specific health care expenditures among the eligible population using the 2010–19 MEPS-restricted state-level data set, adjusted to 2024 US dollars. State-specific data were available for the twenty-nine most-populous states, representing 88 percent of the US population. For the remaining twenty-one states, we extrapolated annual hospitalizations and expenditures using regional averages (Northeast, South, Midwest, and West), excluding data from the twenty-nine most populous states.
Simulation Model
Input data for the simulation model, programmed in R, included state-level eligible populations and demographics, baseline annual hospitalizations and expenditures, MTM intervention effects, and MTM program costs (supplement table 7).11 Model outputs included changes in annual hospitalizations and expenditures, program costs, and net policy costs evaluated from a health system perspective at one year (2024) and five years (2024–28). Five-year outcomes were simulated annually, incorporating trends in eligible populations and health care expenditures, using 2010–19 MEPS data. These trends were estimated using log-linear regression, stratified by region. We assumed that eligible people received meals for eight months annually, as long as they remained qualified, with a summing of outcomes across years and applying 3 percent annual discounting of health care and intervention costs. This assumption was based on studies used to derive the effect size, which had an average duration of treatment around eight months per twelve months of observation.3,12–14,22
Probabilistic Sensitivity Analyses
By randomly drawing from the input parameters’ range in a probabilistic sensitivity analysis, 1,000 Monte Carlo simulations accounted for uncertainty. The central estimate was the mean of 1,000 simulations, with the 95% uncertainty interval from the 2.5th and 97.5th percentiles, assuming a normal distribution.
Secondary Sensitivity Analyses
We performed secondary sensitivity analyses to assess the results’ robustness. First, we restricted the receipt of MTMs to people with diabetes or congestive heart failure. Second, we modeled 50 percent of eligible patients receiving MTMs, instead of 100 percent. Third, we varied the intervention effect size across the 2.5th 10th, 25th, 50th, 75th, 90th, and 97.5th percentiles of the effect size. Fourth, we conducted two threshold analyses to estimate minimum changes in the per meal cost and health care expenditures needed for cost-neutrality. Fifth, we evaluated annual discounting rates of 0 percent and 5 percent. Finally, we estimated sustained health benefits from MTMs, assuming that 15 percent of MTM recipients each year would not require MTMs the following year while maintaining reduced hospitalizations and expenditures.
Strengths And Limitations
Strengths of our study include the use of state-specific data on eligible patients, health care use, and expenditures, allowing us to generate findings relevant to local decision-makers. Effects of MTM treatment were derived from pooled interventional studies and program costs from contemporary insurance contracts between MTM providers and health care systems. Patient eligibility criteria were consistent with prior research and existing MTM programs. Our model incorporated an open cohort and probabilistic sensitivity analyses to jointly incorporate uncertainty and report a range of outcomes. One-way sensitivity analyses tested the influence of specific assumptions. We estimated one-year and five-year outcomes, providing a range of clinically relevant and policy-relevant time horizons.
However, our study also had limitations. Modeling MTMs for patients with severe comorbidities and IADL limitations might not generalize to healthier populations or less intensive nutritional interventions. Also, MTM effects may vary across disease states. However, the included conditions were selected on the basis of prior MTM research, which informed our effect size estimates. These estimates represent a reasonable averaged effect across the selected disease states.
The main analysis assumed full coverage of all eligible people to provide a best-case scenario. In practice, scaling MTM services to reach all eligible people would take time, making a 50 percent coverage sensitivity analysis an informative comparison. Although scaling could enhance program efficiency and reduce costs, it could also affect nutritional quality, necessitating empirical research for evaluation.
Although state-specific data were available for the twenty-nine most populous states, estimates for the remaining states were based on regional means. Smaller eligible populations in smaller states contributed to wider uncertainty intervals, influenced by sample size and variance. However, for policy makers, overall trends and expected benefits often can offer actionable insights despite some uncertainty.
Finally, although we could not jointly stratify results by state and payer because of limited sample sizes, MTMs were cost-effective in nearly all states across Medicare, Medicaid, and private payers, suggesting that substantial divergence by payer type in individual states is unlikely.
Study Results
Size And Characteristics Of The MTM-Eligible Population
An estimated 7.05 million US adults qualify for MTMs. Among the twenty-nine most populous states, the number of eligible patients was generally proportional to the state population, with the largest number in California () and the smallest in Oregon () (supplement table 2).11 Nationally, the mean age was 67.8 years (SD: 16.5); 62.5 percent of the study population were female; and 54.1 percent were non-Hispanic White adults, 23.4 percent were non-Hispanic Black adults, 11.3 percent were Hispanic adults, and 8.0 percent were non-Hispanic Asian adults (exhibit 1). The median household income-to-poverty ratio was 1.8 (interquartile range: 1.0–3.3; supplement table 8),11 and 89.7 percent of patients had Medicare or Medicaid (exhibit 1). The most common eligibility diagnoses were cardiovascular diseases (61.6 percent), diabetes (35.2 percent) and cancer (29.4 percent). Among the sample population, mean annual health care expenditures per person were $30,892 (SD: 45,403), and the annual number of hospitalizations per person was 0.53 (SD: 1.02), highlighting the high severity of illness and health care use.

Projecting One-Year Outcomes
Assuming 100 percent uptake among eligible people, MTMs were projected to generate mean net health care cost savings across all states except Alabama (where MTMs were cost-neutral) (exhibit 2; supplement table 2 and supplement figure 2).11 Nationally, after the intervention costs were accounted for, MTMs were estimated to save $32.1 billion (95% UI: −19.8, 87.9) (supplement table 2).11 States with the largest annual net cost savings were Connecticut ($6,299 per patient; 95% UI: 15, 13,974), followed by Pennsylvania ($4,450; 95% UI: −845, 10,824) and Massachusetts ($4,331; 95% UI: −756, 10,148).
Exhibit 2 Estimated 1-year impact of medically tailored meal (MTM) treatment on per person health care costs, by US state

MTMs would avert a meaningful number of hospitalizations across all states, despite variations (exhibit 3; supplement table 2).11 The number of treated patients needed to avert one hospitalization annually was lowest in Maryland, at 2.3, followed by Massachusetts and Pennsylvania, each at 3.0. Nationally, MTMs were estimated to avert 3,542,500 hospitalizations (95% UI: 2,266,800, 4,786,800) annually (supplement table 2).11
Exhibit 3 Estimated 1-year impact of medically tailored meal (MTM) treatment on hospitalizations, by US state

The annual net per person health care cost savings for each state and averted hospitalizations were modestly correlated (), with meaningful variation (exhibit 4). Maryland had lower cost savings per MTM-treated patient ($3,248; 95% UI: −1,086, 8,352) while requiring the smallest number of treated patients needed to avert one hospitalization (2.3 patients). Conversely, Connecticut reported large cost savings per MTM-treated patient ($6,299) but required a modest number of treated patients to avert one hospitalization (4.1 patients).
Exhibit 4 Relationship between estimated 1-year impact of medically tailored meal (MTM) treatment on hospitalizations and health care costs, by US state, with regional trends

States in the South and Midwest regions demonstrated a higher correlation between per person cost savings and averted hospitalizations, whereas states in the Northeast and West showed more variability (exhibit 4). In the five most populous states, between 195,600 and 265,400 hospitalizations would be averted, with total cost savings of $1.5–$3.7 billion (supplement figure 1).11
Sensitivity Analyses With One-Year Projection
For MTMs serving people with diabetes in our one-year projections, the eligible population would decrease to 5.35 million nationally. MTMs would be net cost saving across all states (supplement table 3),11 with an average savings of $3,403 (95% UI: −1,008, 8,149) per person, representing nearly 150 percent greater savings than in our base case. Per MTM-treated patient with diabetes, states with the largest net cost savings were Connecticut ($11,098; 95% UI: 1,262, 24,164), Washington ($8,702; 95% UI: −463, 19,757), and Pennsylvania ($8,620; 95% UI: 462, 18,982).
When the one-year analysis was restricted to patients with heart failure, 2,896,686 people were MTM-eligible nationally. MTMs for those patients would be net cost saving across all states, with a mean savings of $3,989 (95% UI: −834, 9,109) per person nationally—nearly 174 percent greater than our base case (supplement table 4).11 States with the largest net cost savings per MTM-treated patient were Connecticut ($9,279; 95% UI: 1,262, 18,845), Pennsylvania ($6,876; 95% UI: 21, 14,710), and Massachusetts ($6,686; 95% UI: 129, 13,901).
Assuming 50 percent uptake, MTMs were still estimated to avert 1,771,000 hospitalizations (95% UI: 1,131,200, 2,440,500) and reduce net costs by $16.0 billion (95% UI: −9.9, 44.0) nationally. For a one-year MTM intervention to be cost-neutral, the per meal cost would need to increase from $11.15 to $18.30; the effect size on health care expenditure reduction would need to decrease by around one-third, from 19.7 percent to 12.5 percent.
Projecting Five-Year Outcomes
Based on observed trends among MTM-eligible patients, the eligible population was estimated to increase annually by 2.4 percent (Northeast), 1.7 percent (Midwest), 2.4 percent (South), and 0.3 percent (West) over a five-year period. Inflation-adjusted health care expenditures would increase annually in our sample by 1.5 percent (Northeast), 5.6 percent (Midwest), 1.3 percent (South), and 1.4 percent (West) during these five years. In 2024 dollars with 3 percent discounting, five years of MTM intervention could prevent 14,668,000 (95% UI: 9,919,000, 19,481,000) hospitalizations (supplement table 6)11 and gain $151.0 billion (95% UI: −59.4, 382.3) in net savings nationally. Total projected state-level findings for five years generally mirrored those observed in the one-year projection (supplement figure 1).11
Sensitivity Analyses With Five-Year Projection
For 5.0 percent discounting and 0 percent discounting, five-year net cost savings were $137.2 billion (95% UI: −53.9, 347.3) and $175.1 billion (95% UI: −68.8, 443.2) (supplement table 6).11 Assuming that MTM benefits were sustained into the second year for 15 percent of people (3 percent discounting), MTMs could generate net cost savings across all states, totaling $227.5 billion (95% UI: 19.4, 456.4; data not shown) nationally during the five-year projection period.
Discussion
Our simulation model estimated that state-level MTM coverage among Medicare, Medicaid, and privately insured patients with diet-sensitive conditions and IADL limitations would be associated with reductions in annual hospitalizations and health care expenditures for nearly all states. The overall net cost savings ranged from $6,299 per patient (Connecticut) to cost-neutrality (Alabama). The number of treated patients needed to avert one hospitalization in a year ranged from 2.3 (Maryland) to 6.9 (Colorado).
The variation in MTM outcomes by state can be attributed to eligible population sizes, baseline annual health care expenditures, annual hospitalizations, and state-specific health care management strategies. States with the largest net cost savings, such as Connecticut ($6,299), Pennsylvania ($4,450), and Massachusetts ($4,331), reported high baseline health care costs per capita.24 Maryland was estimated to require the smallest number of treated patients to avert one hospitalization (2.3 patients) but had relatively lower net cost savings per MTM-treated patient ($3,248) than other similar states with higher costs, such as Massachusetts (3.0 patients and $4,331) and Pennsylvania (3.0 patients and $4,450). These findings were likely driven by population health and state-level factors in health care delivery. For example, Maryland hospitals operate under a unique global budget program, which sets fixed annual budgets for hospital operations.25–27 Although this program discourages unnecessary admissions, it also limits the direct financial benefits that hospitals can realize from each averted hospitalization, in part because of Maryland’s higher baseline number of hospitalizations.
Overall, the modestly correlated state-level net cost saving and averted hospitalizations () align with previous findings, suggesting potential inefficiency in health care practices in some states.28,29 Although meal costs may vary by state, this variation is unlikely to have influenced the overall conclusion, as the cost-neutrality threshold ($18.30) is much higher than the highest reported per meal cost among the major MTM organizations we surveyed. In addition, using BRFSS data to estimate eligibility led to a higher number of eligible people (14.0 million) and greater estimated net cost savings ($32.5 billion) nationally (supplement table 2),11 compared with a previous national-level analysis using MEPS data (6.3 million people, $13.6 billion).6 This difference is primarily due to a higher proportion of adults reporting limitations in IADLs in the BRFSS (7.2 percent) compared with MEPS (3.2 percent).
Most long-term MTM programs use eligibility criteria beyond specific diseases, often considering other factors linked to higher health care use. These decisions are typically made by clinical providers or social workers case by case. Among the eight MTM studies informing our effect sizes, one explicitly included disability as a criterion, reporting a greater effect size than found in other studies.12 Other programs included criteria such as recent hospital discharge with home health or hospice care, indicating likely functional limitations. Because national data lack details on clinical acuity, we used IADL limitations as a proxy to identify higher-need patients. Discussions with major MTM providers confirmed this as a reasonable approach to identifying such patients.
Although the availability of MTM services remains uneven, interest in improving access to such programs has grown through a national network of nonprofit providers that provide training and technical assistance to new programs.30 There has also been a proliferation of for-profit MTM providers.31 We included published interventional studies that used nonprofit providers managing meal delivery through health systems, although some studies also involved commercial providers.32 Similar evaluations of for-profit providers are critical to ensuring that nutritional standards and health benefits are not diminished. For example, an analysis by STAT News identified the low nutritional quality of MTMs provided by a for-profit provider to several Medicaid programs.33 In general, we would expect that the provision of less healthy meals would likely be less effective than our findings, given that the effects of MTMs on hospitalizations and health care use stem in part from improved diet quality.6
Most interventional evaluations have been quasi-experimental. There remains a need for large randomized controlled trials (RCTs). In a pilot RCT among 161 patients hospitalized with heart failure, MTMs reduced hospital readmissions by 46 percent at five months and 41 percent at nine months compared with controls.21 Conversely, a larger trial among nearly 2,000 patients who had recently been discharged with heart failure, diabetes, or chronic kidney disease19 found reductions in hospitalizations only in patients with heart failure. However, the intervention was short (mean of 6.9 weeks), and longer periods may be necessary to affect hospitalizations. A recent RCT enrolling patients with HIV found an 89 percent reduction in hospitalizations after six months of receiving MTMs, underscoring the potential for greater impact with longer intervention periods.34
Although cost analyses are relevant to payers’ coverage decisions, the primary goal of MTM programs is to provide high-quality medical care for patients with diet-sensitive chronic illnesses. These programs should not be viewed as cost containment strategies—a high bar that is unrealistic for most therapies, preventive services, and diagnostic testing used in health care today.35 In addition, the estimated effects on hospitalizations and health care expenditures do not incorporate potential additional benefits of MTMs for quality of life, disease progression, caregivers’ well-being, and health equity.
Our findings support the implementation and evaluation of MTM programs in public and private health systems at the state level.
Our findings support the implementation and evaluation of MTM programs in public and private health systems at the state level. As of January 2025, sixteen states had approved or proposed Medicaid Section 1115 waivers, enabling MTM treatment coverage and representing a major pathway to standardizing MTM treatment (Kathryn Garfield, Harvard University, personal communication, January 18, 2025). However, Section 1115 waivers often employ restrictive eligibility criteria and require cost-neutrality, and they require frequent renewal by the Centers for Medicare and Medicaid Services. In our study, 89.7 percent of patients were covered by Medicare or Medicaid, highlighting the importance of these programs in facilitating MTM access. Many Medicare Advantage plans are also starting to include MTMs to help improve chronic conditions and patient outcomes.36
Conclusion
Our state-level simulation model estimated that coverage for MTMs in Medicare, Medicaid, and private insurance for patients with diet-sensitive conditions and IADL limitations could prevent hospitalizations in fifty states and be net cost saving in forty-nine states. These findings, including variations across states, can help inform state-level policy makers and health plans that are considering implementing MTMs in clinical care through state-specific strategies.
