Cut through the noise, find the signal: Intelligence for serious healthcare leaders
Analysis updated November 9, 2026
Model Status: Active | End Date: December 31, 2026 | Total Federal Investment: ~$126M across 7 active awardees
InCK is structurally unlike any CMMI model targeting adult populations. Its authority under Section 1115A is familiar, but its operational DNA is a multi-sector cooperative agreement model, not a shared savings or episode payment model. CMS awarded up to $16 million per awardee over seven years — funding that explicitly cannot pay for direct beneficiary services. Every dollar funds infrastructure: staff training, data-sharing arrangements, SIL stratification processes, and APM design. This is a deliberate constraint that reveals CMS's actual hypothesis: the problem in pediatric Medicaid is coordination failure, not insufficient service funding.
The three-tier Service Integration Level (SIL) architecture is the model's core design innovation. SIL 1 captures the full attributed population (birth to age 21, Medicaid/CHIP-enrolled) via administrative assessment. SIL 2 and SIL 3 trigger progressive care management intensity, with SIL 3 reserved for children at imminent risk of out-of-home placement (OOHP) — encompassing foster care episodes, long-term care facility placement, and behavioral health inpatient hospitalizations. The OOHP composite measure is the model's most consequential accountability lever: it is the single metric that connects behavioral health, child welfare, and Medicaid financing in a way no prior CMMI model has attempted.
The APM design flexibility is both InCK's greatest strength and its most significant structural risk. Six of seven awardees chose PMPM-with-quality-incentives structures; one (NY InCK at Montefiore) designed a shared savings model tied to MCO contracts covering only 22% of the attributed population by end of 2023. The MCO contracting dependency is the model's hidden chokepoint: the evaluation data confirms that partial MCO coverage directly limits APM reach. Village InCK's APM covered 50% of its population; OH InCK's covered 50%. These aren't implementation failures — they reflect the structural difficulty of negotiating pediatric APMs into managed care contracts in states where pediatric value-based contracting has historically had low MCO priority.
The $3.00 PMPM quality incentive + $1.50 PMPM total cost of care incentive structure at All Hands InCK (Lurie Children's) represents the clearest real-world test of pediatric provider-level financial accountability CMMI has run. By end of 2023, All Hands had distributed $246,421 in incentive payments to its provider network — a figure that illuminates both the scale problem and the potential: this is a pilot operating within two ZIP codes of Chicago covering 41,478 attributed beneficiaries. Per-beneficiary incentive spending is roughly $5.95 against a total cost of care baseline of approximately $205.96 per beneficiary per quarter (roughly $824/year). The incentive is less than 1% of baseline TCOC — adequate to signal accountability but unlikely alone to drive behavioral change at scale.
Break-even arithmetic is unfavorable in the near term. Using All Hands InCK as the test case: the model engaged 1,776 beneficiaries in screen-based assessments (4.3% of 41,478 attributed) and provided integrated care coordination to 553 beneficiaries over two implementation years. Service Integration Coordinators carried caseloads of 3 to 26 beneficiaries per month — far below the projected 60 to 90 per coordinator. At 12 coordinators fully staffed, actual utilization efficiency is roughly 15-35% of original projections. The model's federal funding subsidy masks this inefficiency during the award period.
The critical sustainability question arrives December 31, 2026, when cooperative agreement funding ends. The APM is designed to self-fund care coordination through provider incentive payments — but the $4.50 PMPM ceiling at All Hands (increased from $1.50 PMPM in 2022) generates approximately $186,651 per month against the full attributed population if every eligible beneficiary generates payment. That annualizes to roughly $2.24M — a meaningful but thin operational budget for a program requiring community-based Service Integration Coordinators, data infrastructure, and MCO contract maintenance across five MCOs.
Village InCK is the model's most encouraging financial signal. The evaluation detected a statistically significant 4.8% relative reduction in total cost of care compared to the control group, driven by decreases in "other services" costs. For a population of 11,366 beneficiaries at a baseline TCOC trajectory, even a modest per-member savings produces meaningful aggregate Medicaid expenditure reduction. This is the only awardee with a detectable cost impact at the end of Implementation Years 1 and 2 — and notably, it is the rural awardee with the smallest attributed population, suggesting that high baseline service fragmentation in rural geographies may create greater margin for improvement.
NC InCK's 2.9% increase in well-child visits accompanied by a 3.3% increase in TCOC is the model's cautionary data point: better preventive care access produces short-term cost increases before downstream savings materialize. Health systems considering InCK-adjacent programs should model a 3-5 year horizon before net cost reduction and build that assumption into any sustainability pitch to state Medicaid.
Federally Qualified Health Centers and children's hospitals are the natural institutional winners in InCK's governance structure. The Lead Organization must be a HIPAA-covered entity with existing community trust, multi-sector partnership capacity, and tolerance for cooperative agreement compliance requirements. Lurie Children's (All Hands) and Nationwide Children's (OH InCK) exemplify this archetype: academic children's hospitals with established community benefit programs, existing MCO relationships, and research infrastructure to meet evaluation data obligations.
Community mental health centers and behavioral health systems are structurally disadvantaged despite being the most relevant care providers for SIL 2 and SIL 3 children. They lack the Medicaid contracting infrastructure to anchor a Lead Organization role, and the model's behavioral health APM measures (at All Hands) were still undefined at end of 2023 — meaning behavioral health providers received no performance payments in the first two implementation years despite being central to the model's theory of change.
Medicaid MCOs face asymmetric pressure. They are required as contracting partners but receive no direct cooperative agreement funding. Their incentive to negotiate pediatric APM contracts is low where pediatric attribution constitutes a small share of total Medicaid enrollment. States with strong Medicaid managed care oversight (NC, NJ) achieved faster MCO contract completion; states where plans have more negotiating latitude showed persistent partial coverage gaps. MCOs with existing pediatric quality measure infrastructure (HEDIS Well-Child, Childhood Immunization Status) have lower integration costs and should position as preferred APM partners rather than passive contract signatories.
Interaction with OhioRISE is the most instructive program overlap case. OH InCK explicitly excluded OhioRISE enrollees from SIL stratification — ceding care management of the highest-acuity children to a parallel state program. This carve-out reduces OH InCK's potential impact on OOHP rates (its primary outcome measure) while also creating attribution clarity. Organizations operating in states with existing high-acuity pediatric care management programs must model this exclusion into their reach projections before assuming InCK-scale outcomes.
Pediatricians: The $3.00-$4.50 PMPM incentive at All Hands is material at practice scale if attribution is clean — a PCP with 200 attributed InCK beneficiaries could receive up to $10,800 annually for reaching HEDIS 90th percentile performance. The attribution accuracy problem documented in the evaluation (incorrect PCP attribution delayed 2022 payment distribution) is the primary operational risk. Practices must invest in patient panel reconciliation or face payment deferrals. PCPs in rural attributed regions have stronger ROI potential given lower HEDIS baseline rates and larger relative improvement opportunities.
Health Systems: The governance burden is substantial: Lead Organizations must convene Partnership Councils, maintain MCO contracts across multiple plans, operate data-sharing infrastructure, submit quarterly SIL data files, and produce annual operational plans under cooperative agreement compliance requirements. For an academic children's hospital, this maps onto existing research and community benefit infrastructure. For a health department (Egyptian Health Department, Village InCK), it represents a significant capacity stretch that the $16M award ceiling must cover entirely.
Hospitals: Avoidable inpatient behavioral health admissions are explicitly tracked in the OOHP composite measure. Hospitals with high rates of preventable pediatric behavioral health inpatient utilization face the most direct accountability pressure — and the most to gain from InCK-aligned care management that diverts admissions to community settings. Mobile crisis response integration is a required core child service under the model and represents the specific intervention most likely to bend the inpatient behavioral health admission curve.
Payers/MA Plans: InCK is a Medicaid-only model — Medicare Advantage plans have no direct role. However, the model's SIL stratification methodology and multi-sector needs assessment infrastructure represent replicable assets for MA plans building pediatric and young adult complex care programs in commercial or Medicaid managed care lines. Plans operating Medicaid managed care contracts in InCK states should monitor APM performance data from Evaluation Report 4 (covering implementation years 2024-2026) as a build-vs-buy decision point for pediatric complex care infrastructure.
Bottom Line: InCK is a proof-of-concept infrastructure investment, not a mature payment model. With the model ending December 31, 2026, the next 18 months will determine whether state Medicaid agencies embed InCK's APMs and care coordination infrastructure into permanent managed care contract requirements — or allow the model to dissolve at award expiration. Organizations with sustainability leverage (state Medicaid agency as Lead Organization, existing MCO relationships, durable behavioral health workforce) are best positioned to convert federal investment into ongoing program infrastructure.
