Question
How did care settings change among publicly-insured children with a depression diagnosis in 2020 compared with 2016 to 2019, and were changes associated with receipt of minimally adequate care?
Findings
This cross-sectional study using claims data from 799 452 publicly insured children with depression in 41 states and Washington, District of Columbia, found that use of telemental health care increased in 2020 compared with 2016 to 2019. Children who received telemental health services in 2020 were more likely to receive minimally adequate treatment than those who received services in clinic settings only.
Meaning
The findings of this study support continued telemental health coverage by public insurance programs to ensure access to mental health care.
This cross-sectional study estimates rates and associations of telemental health care with receipt of depression treatment among publicly insured children and adolescents.
Abstract
Importance
The prevalence of depression among children and adolescents has increased, yet many do not receive adequate treatment. The rise of telemental health care highlights the need to examine how delivery setting changes are associated with depression care.
Objective
To estimate the association between service delivery setting (telehealth vs clinic-only care) and the receipt of mental health treatment among publicly insured children and adolescents with depression.
Design, Setting, and Participants
This cross-sectional study of publicly insured children and adolescents (ages 3-17 years) with an index depression diagnosis used multistate claims data from 41 states and Washington, District of Columbia, to examine the association between health service setting and minimally adequate depression care in 2016 to 2019 (before COVID-19) and 2020. Data were analyzed from June 14, 2022, to March 15, 2024.
Exposure
Mental health service setting categories included most mental health services via telehealth (>50%), some mental health services via telehealth (≤50%), any in-home visits (no telehealth), any in-school visits (no telehealth or in-home visits), and clinic-only visits (reference group).
Main Outcomes and Measures
Outcomes of interest were dichotomous measures of at least 4 mental health visits within 12 weeks of index diagnosis, minimally adequate pharmacotherapy (≥84 days of antidepressant medication fills within 144 days of index diagnosis), and minimally adequate treatment (≥4 visits or minimally adequate pharmacotherapy). Multiple logistic regressions controlled for individual- and contextual-level covariates, state, and year of index diagnosis (2016-2019 vs 2020).
Results
Among 799 452 publicly insured children with an index depression diagnosis from 2016 to 2020, most were aged 12 to 17 years (640 738 [80.1%]) and female (469 014 [58.7%]). The percentage with any telemental health visit increased from 4.5% before the COVID-19 pandemic to 49.8% in 2020, while clinic-only care declined from 76.8% before COVID-19 to 43.1% in 2020. In 2020, children receiving some or most mental health services via telehealth were more likely to receive minimally adequate depression treatment than those receiving clinic-only services (some telehealth: 50.9%; mostly telehealth: 54.5%; clinic-only: 32.1%; P < .001 for both comparisons). Differences remained significant in regressions (some telehealth: marginal effect [ME], 16.1 [95% CI, 14.6-17.6] percentage points; mostly telehealth: ME, 19.8 [95% CI, 18.2-21.5] percentage points).
Conclusions and Relevance
In this cross-sectional study of publicly insured children and adolescents, receipt of telemental health services in 2020 was positively associated with minimally adequate depression care. These findings underscore the importance of continued telemental health coverage use by state Medicaid programs and Children’s Health Insurance Programs to facilitate access and minimize barriers to mental health care.
Introduction
Depression is one of the most common mental health disorders among children and adolescents, and its prevalence has increased dramatically.1,2 For example, the prevalence of major depression among adolescents in the past year increased from 8.1% in 2009 to 19.5% in 2022.3,4 Moreover, children whose families live in poverty are at increased risk for depression due to increased exposure to traumatic events,5 family disruption,6 and reduced parental involvement.7
Public insurance programs, including Medicaid and the Children’s Health Insurance Program (CHIP), provided coverage to more than 36 million children during each month of 2024,8,9 including those from families with low income, with disabilities, and/or living in foster care. Although effective treatments (including psychosocial services and/or antidepressant medication) are available for children with depression,10,11,12 many do not receive any mental health care.13 Among Medicaid-enrolled children with depression who initiate treatment, rates of treatment discontinuity and dropout are high.13
Prior studies examining care delivered to Medicaid-enrolled children have typically focused on services offered in clinic-based settings.13,14,15 However, barriers exist to children receiving consistent services in clinic-based settings, including distance to the nearest Medicaid-accepting health care practitioner,16,17,18 transportation availability,16,19 and family scheduling conflicts.19,20,21,22 Service delivery models are changing to provide more options for children to receive services outside of clinics, especially with the rapid uptake of telemental health care since 2020.23 Prior to the COVID-19 pandemic, telemental health care availability and coverage was extremely limited in many Medicaid and CHIP programs and often excluded services delivered to the home.24 Additionally, there have increases in community-based service delivery in school25,26 and home settings,27 which also reduce geographic barriers to care. In a 2022 study, Medicaid-enrolled children with depression who received in-home services (vs those who did not) were significantly more likely to receive at least 4 psychosocial service visits in the first 12 weeks of treatment and had a longer treatment episode duration.27
To date, there is little information about whether service delivery in other settings that reduce geographic barriers, including telehealth or school settings, is associated with changes in mental health care received among publicly insured children with depression. Using multistate claims data, we examined how health care settings were associated with the receipt of mental health care among publicly insured children and adolescents with depression before and after the onset of the COVID-19 pandemic.
Methods
This cross-sectional study received expedited approval from the Emory University institutional review board, with a waiver for the requirement to obtain informed consent because the study used secondary data, posed minimal risk to participants, and could not be practicably carried out without the waiver, as the study team was unable to contact participants if consent had been required. This study is reported following the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline for cross-sectional studies.
Data Sources
Medicaid and CHIP claims data were extracted from the 2016 to 2020 Transformed Medicaid Statistical Information System Analytic Files in the Virtual Research Data Center (VRDC).28,29 Using geographic identifiers (zip code, county, state), we merged area-level measures from the area health resources files,30 the Social Deprivation Index county files,31 and county-level broadband internet connection files.32
Analytic Sample
We derived a sample of publicly insured children and adolescents (ages 3-17 years) with an index depression diagnosis in 2016 to 2020 using the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) codes listed in eTable 1 in Supplement 1 on at least 1 inpatient or 2 outpatient health care claims during the study period. To identify the index diagnosis, we required a 90-day period preceding the index visit (ie, a lookback window) without any depression diagnosis, any mental health visit identified with relevant procedure codes (eTable 2 in Supplement 1), and/or any filled antidepressant medication (eTable 3 in Supplement 1) identified with relevant National Drug Codes.13,18,27 We further required continuous Medicaid/CHIP enrollment during the 270 days prior to the index date until 144 days after the index visit, allowing for an administrative enrollment gap of 30 days. Continuous enrollment ensures a sample with stable insurance coverage for the year when each outcome is assessed and facilitates the capture health services utilization for the lookback window and outcome assessment. For children with multiple depression episodes identified, we only included their first episode. Through this process, we identified 1 188 764 children with an index depression diagnosis during the study period (eFigure in Supplement 1).
From this sample, we excluded 83 879 children for whom any part of their episode window (index visit to 144 days after) and the 90-day lookback window occurred outside of the 2016 to 2020 timeframe. To be able to determine service delivery setting for outpatient care, we also excluded children without any outpatient visits that had a depression diagnosis (eTable 1 in Supplement 1) or a mental health–related procedure code (eTable 2 in Supplement 1) in the 144-day period following the index visit. Next, we excluded 47 828 children who had Medicaid records from multiple states and 48 690 children who were missing information on demographic and geographic characteristics. Finally, we excluded 195 522 children living in 9 states that were classified as having high data quality concerns on the primary files used (ie, other service files and pharmacy files).33 Our primary analytic sample included 799 452 children from 41 states and Washington, District of Columbia (DC), and we conducted sensitivity analyses with a sample of 994 974 children from all 50 states and Washington, DC. The sample derivation process is presented in eFigure in Supplement 1.
Outcome Measures
Clinical guidelines have stated that depression among children and adolescents can be treated with psychosocial services and/or antidepressant medication, depending on the severity and presentation of symptoms.10,11,12 Treatment includes an acute phase (with a goal to achieve response and ultimately remission) and a continuation phase (to secure response and avoid relapse). Drawing on clinical guidelines and prior literature,10,11,12,13,14,18 we created 5 dichotomous variables to measure depression treatment and receipt of minimally adequate care in the acute phase. We used 2 dichotomous indicators to assess treatment initiation: (1) any mental health visit for those with at least 1 outpatient health care claim with a mental health–related Current Procedural Terminology code, including psychotherapy, psychosocial services, case management, or other mental health services (eTable 2 in Supplement 1) within 12 weeks (ie, 84 days) of the index diagnosis, and (2) any pharmacotherapy for individuals who filled an antidepressant prescription during the 144 days following their index visit (eTable 3 in Supplement 1). Next, an indicator was created for those who received at least 4 mental health visits within 12 weeks of the index diagnosis. A 4-visit threshold has been used in prior studies,13,14,18 and evidence from the literature suggests that brief interventions with children can lead to reductions in depression symptoms within 4 sessions.11,34 Fourth, consistent with prior studies,13,14,18 an indicator for minimally adequate pharmacotherapy assessed whether a child had antidepressant prescription fills that covered at least 84 days of the 144 days following their index depression diagnosis. A fifth measure of minimally adequate care identified individuals who received at least 4 mental health visits and/or minimally adequate pharmacotherapy. Notably, this final indicator is meant to capture a minimum, conservative threshold of mental health care that should be received by any child with depression rather than the level of care needed for a full course of treatment.
Health Care Setting
We used data from the other service files to measure the service delivery setting for mental health care. Specifically, we extracted all mental health–related visits, defined as outpatient health care claims with a mental health diagnosis (eTable 1 in Supplement 1) or with a mental health–related procedure code (eTable 2 in Supplement 1) during the first 12 weeks (84-day) window following the index diagnosis. We used the place of service code on each claim to classify service delivery setting, which provides information about where the service was performed. We identified services delivered through telehealth using the place of service code (02), modifiers (GT, GQ, or 95), and/or telehealth-specific procedure codes (T1014, Q3014, G0425-G0427, G0406-G0408, G0459, G0508, G0509, 0188T, 0189T, 98966-98968, 99441-99444, 99421-99423, G2061-G2063).35,36 Services delivered at the child’s home (ie, “Location other than a hospital or other facility, where the patient receives care in a private residence”37) were identified using place of service code 12. Services delivered at the child’s school (ie, “a facility whose primary purpose is education”37) were identified using place of service code 03. The remaining claims were classified as clinic setting.
Because prior research reported major shifts to telemental health services in 2020 for publicly insured children23,38 and because telemental health services reduce logistical barriers to care for this population,39 the association between service delivery via telehealth and the receipt of depression care was a focus of this study. Thus, consistent with prior research examining a service delivery setting of interest,18 we implemented priority coding to create a categorical variable of service delivery setting with 5 mutually exclusive groups. We first identified children who received some, but not most (≤50%), mental health visits via telehealth (ie, some telemental health visits) and most mental health visits (>50%) via telehealth. Children who did not receive any telemental health visits were then classified into the remaining 3 groups: at least 1 in-home mental health visit, but no telemental health visits; at least 1 in-school mental health visit, but no in-home or telemental health visits; and visits only in the clinic setting (ie, clinic only).
Covariates
Covariates were informed by the behavioral model of health services use by Andersen and Davidson.40 Individual-level covariates included predisposing (ie, age, sex, race and ethnicity), enabling (ie, Medicaid health plan type and eligibility category at index visit), and need-related characteristics (ie, coexisting mental health conditions). Race and ethnicity were self-reported and categorized as Hispanic, non-Hispanic American Indian or Alaskan Native, non-Hispanic Asian or Pacific Islander, non-Hispanic Black, non-Hispanic multiracial group or unknown, and non-Hispanic White.41 Six indicators for coexisting mental health conditions were identified in the 144-day observation period following index diagnosis, using at least 1 inpatient or 2 outpatient claims associated with the appropriate diagnosis codes (eTable 1 in Supplement 1).
At the county level, we included several covariates that that were associated with the receipt of telemental health services among Medicaid-enrolled children in prior research.38 These include the percentage of Black residents (quartiles), percentage of Hispanic residents (quartiles), Social Deprivation Index (quartiles), and metropolitan status. We also included an additional measure of county-level infrastructure that may be correlated with the receipt of telemental health services: the percentage of households with broadband connections with downstream speed at least 10 megabits per second.42
Statistical Analysis
Given the change in health care delivery landscape and telehealth policy changes during the COVID-19 public health emergency,43,44,45 the associations between health care setting and depression treatment receipt may differ in 2016 to 2019 vs 2020. Thus, we examine health care setting for these 2 time periods. In bivariate analyses, comparisons for each outcome in a given setting across time (2020 vs 2016-2019) were conducted with χ2 tests. In regression analyses, we used generalized estimating equations with a binomial distribution and logit link function to examine the association between health care setting and each outcome, adjusting for covariates, state of residence, and an indicator for year of index diagnosis (2016-2019 vs 2020). To facilitate interpretation in terms of probability changes of the study outcome associated with care settings and study covariates,46 we converted odds ratios into marginal effects (MEs) using the margins macro program47 in SAS statistical software version 7.1 (SAS Institute). MEs were estimated as average MEs, in which predicted probabilities were first calculated for each individual based on their observed covariate values, and then we calculated the mean across the sample rather than fixing covariates at their sample means. Furthermore, we interacted health care setting and a pre-post (2016-2019 vs 2020) indicator in the regression models, generating separate MEs for each period. Standard errors were clustered at the county level. All data analysis were conducted using SAS Enterprise Guide version 7.1 (SAS Institute) through the VRDC.48 Statistical significance was determined using 2-sided tests and P < .05. Data were analyzed from June 14, 2022, to March 15, 2024.

The annual number of children with an index depression diagnosis was greater during the pre–COVID-19 period (mean per year, 175 332 children; 701 327 children across 2016-2019) than in 2020 (98 125 children) (Table 1). Among children with an index depression diagnosis, the percentage with some telemental health visits increased from 4.1% in 2016 to 2019 to 27.3% in 2020, and the percentage of children who received the most mental health visits via telehealth increased from 0.4% in 2016 to 2019 to 22.5% in 2020 (Figure). The receipt of services in other settings declined (in-clinic only services: 76.8% to 43.1%; any in-home services [no telemental health]: 11.3% to 4.4%; any in-school services [no in-home or telemental health]: 7.3% to 2.6%).
Figure. Mental Health Care Setting Among Publicly Insured Children With Depression.
Data were collected from the T-MSIS analytic files (2016-2020) for 41 states and Washington, District of Columbia. The sample included 799 452 children aged 3 to 17 years with an index depression diagnosis. For children with multiple depression episodes identified, only the first episode was included.
Receipt of Mental Health Visits
Among children who received services in clinic-only settings, the percentage who received at least 4 mental health visits decreased from 28.3% in 2016 to 2019 to 20.5% in 2020 (P < .001) (Table 2). Yet, the percentage who received at least 4 mental health visits increased from 32.7% in 2016 to 2019 to 38.3% in 2020 among children who received some mental health services via telehealth (P < .001), and from 7.1% in 2016 to 2019 to 46.3% in 2020 among those who received most services via telemental health (P < .001).

Receipt of Minimally Adequate Pharmacotherapy
The percentage who received any pharmacotherapy declined in all settings in 2020 compared with 2016 to 2019 (Table 2). Moreover, the percentage who received minimally adequate pharmacotherapy declined in many settings (Table 2). In 2020, the percentage of children who received minimally adequate pharmacotherapy was 14.0% among those who received clinic-only services, 14.4% among those who received most mental health services via telehealth and 20.5% among those who received some services via telehealth. In regression analyses, the adjusted percentage of children who received minimally adequate pharmacotherapy in 2020 was 4.84 (95% CI, 4.18-5.49) percentage points higher among those who had some visits via telemental health and 0.69 (95% CI, 0.06-1.31) percentage points higher among those who received most visits via telemental health, compared with children who received in-clinic only services (model-adjusted predicted probability, 13.3%). (Table 3; eTable 5 in Supplement 1).
Receipt of Minimally Adequate Treatment
During the study period, the receipt of minimally adequate depression treatment declined among children who received services in person only (Table 2). Among children receiving clinic-only services, for example, the receipt of any minimally adequate treatment decreased from 38.7% in 2016 to 2019 to 32.1% in 2020 (P < .001) (Table 2). In contrast, the percentage of children who received any minimally adequate treatment increased from 2016 to 2019 to 2020 among children receiving some services via telemental health (46.1% to 50.9%; P < .001) or most services via telemental health (27.1% to 54.5%; P < .001). The increase in minimally adequate treatment among children receiving telemental health care, combined with the steep increase in telemental health services, translated into an overall small increase in the percentage of children who received minimally adequate treatment in the entire sample—from 39.8% during 2016 to 2019 to 42.6% in 2020 (P < .001).
In regression analyses, the adjusted percentage of children who received any minimally adequate care in 2020 was 32.3% among those who received services in-clinic only (Table 4; eTable 6 in Supplement 1). This number was 16.1 (95% CI, 14.6-17.6) percentage points higher among those who received some services via telemental health and 19.8 (95% CI, 18.2-21.5) percentage points higher among those who received most services via telemental health.

The receipt of minimally adequate depression treatment is a dichotomous indicator for whether the child received at least 4 mental health visits in 12 weeks following index diagnosis or minimally adequate pharmacotherapy.
Estimates represent the adjusted percentage point change in each outcome variable associated with the setting of interest compared with the reference group, clinic-only care. Regression models controlled for child-level and county-level covariates listed in Table 1 and included state fixed effects, year indicators, and an interaction term between year and health care setting. SEs were clustered at the county level.
Sensitivity Analyses
Results of analyses that adjusted the P values for multiple tests of 5 outcomes using the conservative Bonferroni adjustment (P < .01) were generally consistent with 2 exceptions. The findings for children who received most mental health visits via telehealth vs clinic-only settings were significant at the P < .05 level when examining the outcome measures of any pharmacotherapy and minimally adequate pharmacotherapy in 2020. Findings from sensitivity analyses conducted among all states and Washinton, DC, regardless of data quality were consistent with the main findings with respect to direction, magnitude, and significance (eTable 7 and eTable 8 in Supplement 1).
Discussion
To our knowledge, this cross-sectional study is the first study examining whether changes in service delivery settings after the onset of COVID-19 were associated with the receipt of minimally adequate depression treatment among publicly insured children. First, among children with an index depression diagnosis, there were large shifts toward telemental health services in 2020. In addition, those who received some or most mental health services via telehealth in 2020 (vs those who received in-clinic only services) were more likely to receive minimally adequate mental health treatment. Finally, the increase in percentage of children who received telemental health care, combined with the large increases in minimally adequate treatment among those who received any telemental health care, was associated with a small increase in the receipt of any minimally adequate treatment across the entire sample, from 39.8% in 2016 to 2019 to 42.6% in 2020.
Our findings add to the literature on the health care system disruptions and transitions in 2020, including temporary closures of outpatient clinics at the onset of pandemic, as well as the shift to telemental health services during 2020 for children with mental health disorders.23,49,50 These results indicate that the disruptions in care had implications for the number of children with an index depression diagnosis in 2020, as this was lower than the mean in the years preceding the pandemic. With respect to health care setting transitions, more than half of children with an index diagnosis in 2020 received any telemental health visit. Furthermore, we documented a decline in other settings in which care was received in person, including clinics, homes, and schools.
Not only was there a significant shift to telemental health care, but the receipt of telemental health services was strongly associated with the receipt of minimally adequate treatment in 2020. For those who received care in person only (including in clinics, homes, and/or schools), the percentage of children who received minimally adequate treatment declined in 2020 compared with the pre–COVID-19 period. One explanation is that there were more disruptions in care for children who relied exclusively on in-person visits, due to safety measures and procedures implemented by health care organizations early in the pandemic.51 For example, the National Council on Behavioral Health indicated that more than half of mental health care clinics ceased their programs and almost two-thirds either canceled, rescheduled, or refused patients.49 On the patient side, fear of seeking in-person services during the early part of the pandemic may have led to disruptions in mental health visits and/or medication management visits.52 On the other hand, the positive association between the telemental health service use and the receipt of any minimally adequate care was partially driven by a large increase in the likelihood of receiving of at least 4 mental health visits. The greater likelihood of receiving at least 4 mental health visits can reflect an advantage telehealth provides with respect to addressing the logistics of psychotherapy and psychosocial services, including frequency of sessions, distance to mental health practitioner, transportation availability, and family schedules.19,20,39,53
The substantially higher likelihood of receiving minimally adequate treatment among children who had some or most visits via telemental health translated into a small but significant increase in the likelihood of receiving any minimally adequate care in 2020 in the entire sample compared with earlier years. It is notable that there was any increase in the percentage of children receiving minimally adequate care during a time when there were significant disruptions in care.49,50 These findings highlight the potential of hybrid depression care, in which at least some services are delivered via telemental health, to help publicly insured children receive enough services, such that there is an opportunity to gain clinical benefit. Prior to COVID-19, very few states allowed Medicaid beneficiaries to receive telehealth services in their homes.24 During 2020, flexibilities to telehealth reimbursement policies were instituted in Medicaid programs nationwide.24 Yet, after the COVID-19 public health emergency ended in May 2023, flexibilities in these policies began to sunset in some states24 and gave rise to increased state variability in continued coverage for various telehealth modalities.54,55 Future research will be needed to monitor the receipt of hybrid care among publicly insured children in need of depression treatment and whether hybrid care continues to facilitate higher rates of minimally adequate treatment.
Limitations
There are several study limitations. First, causality in the associations of interest cannot be established due to the observational study design. Second, although the analyses included measures of comorbid mental health disorders, there remain unmeasured differences in the presentation and severity of depression in the sample. Prior studies have reported that individuals with more severe mental health symptoms are less likely to receive care via telemental health,56,57 while mental health symptom severity is positively associated with the receipt of minimally adequate care.18 To the extent that this is true in our sample, the associations that were estimated between telemental health service utilization and the receipt of minimally adequate care would be biased toward the null hypothesis; in other words, stronger measurement of clinical severity may yield larger effect sizes for these associations. Third, we only included the first depression episode among children in our sample; thus findings may not generalize to additional episodes. Fourth, administrative claims data can include measurement errors because the data are generated for billing purposes.58,59,60,61 Moreover, there is variation in the quality of the T-MSIS analytic files data that were used for this study.33,62 To address this limitation, our primary analysis was conducted with 41 states and Washington, DC, that do not have high concerns in the other service files and the pharmacy files.
Conclusions
The findings of this cross-sectional study highlight the extent to which publicly insured children with a depression diagnosis received telemental health services in 2020 compared with earlier years. These findings also demonstrate large and significant associations between receipt of telemental health services and the receipt of minimally adequate depression treatment after the onset of the COVID-19 pandemic. Continued coverage and monitoring of telemental health use by state Medicaid and CHIP programs is critical to facilitate access and minimize barriers to mental health services.
