GUIDE Model: Guiding an Improved Dementia Experience

Institutional-Grade Strategic Analysis for Healthcare Executives

---

1. Executive Summary and Strategic Context

What Is This Model and What Problem Does It Solve?

The Guiding an Improved Dementia Experience (GUIDE) Model is a voluntary, nationwide, 8-year alternative payment model operated by the CMS Innovation Center (CMMI), running from July 1, 2024 through June 30, 2032. The model funds a comprehensive, standardized package of dementia care services delivered through interdisciplinary care teams to community-dwelling Medicare FFS beneficiaries with dementia and their unpaid caregivers.

The problem GUIDE addresses is structural: more than 6 million Americans currently live with Alzheimer's disease or another form of dementia, a figure projected to nearly double to 14 million by 2060. Dementia prevalence affects roughly 11% of U.S. adults over age 65 and nearly 35% of those over age 85. Despite this scale, the existing Medicare fee-for-service architecture lacks a payment mechanism for the longitudinal, non-physician-billable care coordination that dementia management requires. The result is fragmented care characterized by high rates of hospitalization, emergency department visits, post-acute care utilization, depression, behavioral and psychological symptoms, and poorly controlled comorbidities.

The financial burden is substantial and specific. Out-of-pocket spending in the last five years of life for a person with dementia averages $61,522, compared to $34,068 for those without dementia—representing a 32% share of total family assets versus 11%. From a federal program perspective, dementia drives an additional $12,000–$15,700 in total Medicare costs and $8,800–$31,000 in total Medicaid costs per person over the five years following diagnosis.

Unpaid caregivers—who are frequently Medicare beneficiaries themselves—bear compounding burdens: high rates of stress and depression that independently increase their risk of serious illness, hospitalization, and mortality. GUIDE directly addresses the caregiver as a model participant through required caregiver assessment tools (the Zarit Burden Interview, ZBI-22), tiered payment that adjusts based on caregiver strain, and a federally funded respite benefit capped at $2,500 annually per eligible patient—a benefit type that does not otherwise exist in traditional Medicare outside the hospice benefit.

Strategic Significance for the Value-Based Care Market

GUIDE represents a significant structural expansion of the alternative payment model portfolio. Unlike episode-based or total cost of care models, GUIDE is a disease-specific, per-beneficiary-per-month care management payment model that does not expose participants to shared savings or shared loss. There is no downside financial risk in the traditional sense—participants receive tiered monthly payments adjusted by quality performance and a population/income factor, while continuing to bill traditional Medicare FFS for all services not included in the monthly Dementia Care Management Payment (DCMP).

This architecture makes GUIDE one of the most operationally accessible CMMI models for a broad range of provider types. 292 participants are currently enrolled, spanning health systems, geriatrics practices, telehealth companies, community-based memory care clinics, and primary care practices that have partnered with non-Medicare-enrolled entities. The model explicitly accommodates non-traditional dementia care delivery structures through a Partner Organization mechanism, allowing participants to contract with Area Agencies on Aging, home health agencies, adult day centers, and community-based organizations to fulfill care delivery requirements.

The model's payment design is also differentiated by its health equity infrastructure. A Population and Income Adjustment (PIA) modifies the DCMP based on the socioeconomic composition of a participant's aligned patient population, explicitly incentivizing enrollment of low-income and underserved beneficiaries. A one-time Infrastructure Payment of $75,000 (geographically adjusted via the Medicare PFS Geographic Adjustment Factor) was available to safety-net providers in the New Program Track to support program development—a deliberate mechanism to expand specialty dementia care into underserved and rural markets that currently lack it.

For ACO leaders, GUIDE presents an overlap management challenge and a partnership opportunity. GUIDE participants who are also Shared Savings Program or Innovation Center ACO participants must navigate dual participation rules. The DCMP is explicitly coordinated with ACO total cost of care calculations, and the Payment Methodology Paper contains specific guidance on MSSP and other CMMI model overlaps (including ACO LEAD, introduced in PY 2026 guidance).

Political Context and Administrative Alignment

GUIDE was authorized under Section 1115A of the Social Security Act and launched as a key deliverable of President Biden's Executive Order 14095 (April 18, 2023), which directed HHS to consider testing an innovative dementia care payment model that included caregiver supports such as respite care. The model also advances the National Plan to Address Alzheimer's Disease, established through the bipartisan National Alzheimer's Project Act (NAPA), which retains broad cross-partisan support.

The current Trump administration—with CMS Administrator Dr. Mehmet Oz and CMMI Director Abe Sutton leading the Innovation Center—has not terminated GUIDE. With 292 active participants, the model is past its launch-phase vulnerability window. DOGE-driven scrutiny of CMMI models has focused primarily on total cost of care models with large financial exposure; GUIDE's structure—pay-for-services delivered, no downside risk, explicit nursing-home-avoidance savings thesis—is more defensible on cost-reduction grounds. The bipartisan NAPA foundation further insulates the model from politically motivated termination. The 2026 GUIDE Experience of Care Survey, recently fielded by independent evaluator Mathematica, signals that the formal evaluation infrastructure is active, which typically protects a model from mid-course termination.

Market Transformation Implications

GUIDE is the first Medicare payment model to:

1. Create a new federally reimbursed respite benefit outside hospice, directly funding caregiver relief.
2. Tier payment by caregiver burden as a clinical variable using a validated instrument (ZBI-22) integrated into the payment determination workflow.
3. Require mandatory Health Equity Plans with data collection on sociodemographic characteristics and health-related social needs for all participants.
4. Introduce an RCC-specific model tier (effective PY 2026) that extends coverage to patients in assisted living and group home settings—a previously underserved population in Medicare care management models.

For Medicare Advantage plans, GUIDE is structurally excluded: Medicare Advantage enrollees are ineligible for GUIDE alignment. This creates a competitive consideration—Original Medicare beneficiaries aligned to GUIDE receive a richer care coordination package than MA beneficiaries, potentially influencing plan switching behavior in markets with dense GUIDE participant coverage. MA plan strategists should monitor this dynamic and consider whether supplemental benefit designs can approximate GUIDE's caregiver support and respite structure.

For health system CFOs, the model offers an incremental revenue stream from a population that currently generates disproportionate acute care utilization. The DCMP pays monthly regardless of whether a patient has a clinical encounter in that month, provided a qualifying care delivery service was furnished. The explicit goal of preventing or delaying nursing home placement has a parallel revenue implication: systems that operate skilled nursing facilities or post-acute care networks should model the impact of GUIDE-driven utilization reduction on those service lines.

2. Model Architecture and Payment Structure

Participation Structure

GUIDE Participants are Medicare Part B-enrolled providers and suppliers—excluding DME and laboratory suppliers—that establish Dementia Care Programs (DCPs) and participate under a single, Medicare Part B-enrolled Taxpayer Identification Number (TIN) eligible to bill under the Medicare Physician Fee Schedule. The participant is identified by its TIN plus the National Provider Identifiers (NPIs) of individual Medicare-enrolled physicians and nonphysician practitioners who have reassigned billing rights to that TIN (the "GUIDE Practitioner Roster").

Participants unable to independently meet all care delivery requirements may contract with Partner Organizations—including both Medicare-enrolled and non-Medicare-enrolled entities such as community-based organizations. Partner Organizations must be reviewed and approved by CMS through a program integrity screening before providing services. Residential Care Communities (RCCs) serving as Partner Organizations are subject to enhanced disclosure, oversight, and patient protection requirements and must be formally approved as RCC Partners before any patient residing in that facility can be aligned.

Care Team Minimum Requirements

At minimum, every DCP must maintain:

• One Care Navigator: An individual (not AI) who has completed required training. CMS does not mandate a specific professional background; registered nurses, licensed clinical social workers, and community health workers are explicitly identified as appropriate. Training must cover dementia background, assessments, care planning, person-centered planning, challenging behaviors, and additional required topics.
• One Clinician with Dementia Proficiency: A clinician eligible to bill Medicare Part B evaluation and management services who meets at least one of the following: (i) attestation that ≥25% of their patient panel in the past 5 years had any cognitive impairment; (ii) attestation that ≥25% of their panel in the past 5 years was aged ≥65; or (iii) specialty designation in neurology, psychiatry, geriatrics, geriatric psychiatry, behavioral neurology, or geriatric neurology. If this clinician is a nonphysician, the participant must additionally maintain a part-time physician medical director.

Beneficiary Eligibility

Eligibility Criterion	Requirement
Dementia diagnosis	Confirmed by clinician attestation (not claims codes); mild, moderate, or severe stage; MCI insufficient
Medicare enrollment	Parts A and B; Medicare as primary payer
Medicare Advantage	Not enrolled (including SNPs)
PACE	Not enrolled
Hospice	Not enrolled in Medicare hospice benefit
Residence	Community-dwelling; not a long-term nursing home resident (≥101-day stay)
Residence (PY 2026+)	Must reside in private residence or CMS-approved RCC; Memory Care Units ineligible
Geographic	Within participant's zip code-based service area

Beneficiary alignment is voluntary and ongoing during the first seven years of the model (July 1, 2024–June 30, 2031). No new alignments are permitted in the eighth and final year (July 1, 2031–June 30, 2032) to support organized wind-down. Participants are encouraged to reach a minimum of 200 aligned beneficiaries by the end of their second performance year.

Model Tracks and Timeline

Period	Established Program Track	New Program Track
Nov. 2023–Jan. 2024	Application Period	Application Period
July 1, 2024–June 30, 2025	Performance Year 1	Pre-Implementation Period (no GUIDE billing)
July 1, 2025–June 30, 2026	PY 2	PY 1 (first billing year)
July 1, 2026–June 30, 2027	PY 3	PY 2
July 1, 2027–June 30, 2028	PY 4	PY 3
July 1, 2028–June 30, 2029	PY 5	PY 4
July 1, 2029–June 30, 2030	PY 6	PY 5
July 1, 2030–June 30, 2031	PY 7	PY 6
July 1, 2031–June 30, 2032	PY 8 (wind-down)	PY 7 (wind-down)

The Established Program Track required applicants to have an active interdisciplinary team already delivering at least 6 of 9 GUIDE care delivery domains for at least 12 months prior to the January 30, 2024 application deadline. The New Program Track required only a plan for implementation; the pre-implementation year (July 2024–June 2025) was used for staff hiring, workflow development, provider network building, and community-based organization partnerships. New Program Track participants eligible as safety-net providers received the one-time Infrastructure Payment of $75,000 (geographically adjusted); unspent funds must be repaid to CMS by June 30, 2026 (end of PY 2025).

Payment Methodology

Dementia Care Management Payment (DCMP)

The DCMP is the primary payment mechanism—a per-patient, per-month care management payment in lieu of billing traditional HCPCS codes for a specified set of covered services. Services bundled under the DCMP include: advance care planning (99497, 99498), Annual Wellness Visits (G0438, G0439), Cognitive Assessment and Planning (99483), Transitional Care Management (99495, 99496), Chronic Care Management (99487, 99490, 99491, 99437, 99439, G0506), Principal Care Management (99424–99427), and Advanced Primary Care Management (G0556, G0557, G0558), among others. Participants continue billing traditional FFS for all services not included in Exhibit 7 of the Payment Methodology Paper.

GUIDE G-codes are not subject to the nonphysician practitioner payment reduction (typically 85% of the physician fee schedule) and do not distinguish between facility and non-facility rates.

PY 2026 DCMP Base Rates by Tier

Patient Category	Tier	First 6 Months (New Patient Rate)	After 6 Months (Established Rate)	Respite Eligible?
With caregiver	Low Complexity Dyad	G0519: $157/mo	G0524: $68/mo	No
With caregiver	Moderate Complexity Dyad	G0520: $288/mo	G0525: $126/mo	Yes
With caregiver	High Complexity Dyad	G0521: $377/mo	G0526: $231/mo	Yes
Without caregiver	Low Complexity Individual	G0522: $241/mo	G0527: $126/mo	No
Without caregiver	Moderate-High Complexity Individual	G0523: $409/mo	G0528: $225/mo	No
RCC resident	RCC Tier	G0574: $180/mo	G0575: $70/mo	No

PY 2026 rates reflect a 2.2% increase from PY 2025 rates via the Medicare Economic Index (MEI) adjustment. The 6-month "new patient" clock begins in the first month of alignment, even if that month is partial.

Tiering Criteria and Assessment Tools

Tier	Dementia Stage	Caregiver Strain	Tool Scores
Low Complexity Dyad	Mild	Any	CDR=0-1, FAST=1-4; ZBI=0-88
Moderate Complexity Dyad	Moderate or severe	Low to moderate	CDR=2-3, FAST=5-7; ZBI=0-60
High Complexity Dyad	Moderate or severe	High	CDR=2-3, FAST=5-7; ZBI=61-88
Low Complexity Individual	Mild	N/A (no caregiver)	CDR=0-1, FAST=1-4
Moderate-High Complexity Individual	Moderate or severe	N/A (no caregiver)	CDR=2-3, FAST=5-7
RCC Tier (effective PY 2026)	Any stage	Any/N/A	CDR=0-3, FAST=1-7; ZBI=0-88 if applicable

DCMP Adjustments

Four adjustments modify the DCMP base rate:

1. Performance-Based Adjustment (PBA): Tied to five performance measures—Use of High-Risk Medications in Older Adults; Quality of Life Outcome for People with Neurological Conditions; Caregiver Burden; Total Per Capita Cost; and Long-Term Nursing Home Stay Rate. Beginning in PY 2025, the PBA is partially paid through an interim period payment (IPC). Measure domains, individual contributions, and PY 2025 PBA structure are detailed in Exhibit 12 of the Payment Methodology Paper.

2. Population and Income Adjustment (PIA): Replaces the prior "Health Equity Adjustment." CMS calculates a PIA score based on the socioeconomic composition of the participant's aligned patient population. Exhibit 14 maps PIA score percentiles to the associated adjustment factor applied to the DCMP. This adjustment incentivizes serving low-income, underserved populations.

3. Medicare Economic Index (MEI) Adjustment: Annual inflation-based rate update. PY 2026 rates reflect a 2.2% increase from PY 2025.

4. Geographic Adjustment Factor (GAF): Applies Medicare PFS geographic adjustments to DCMP rates by locality. Appendix C of the Payment Methodology Paper provides examples by locality.

GUIDE Respite Payment

Only patients in the Moderate Complexity Dyad and High Complexity Dyad tiers are eligible for GUIDE Respite Services. Patients in the RCC Tier are explicitly not eligible for respite services.

• Annual cap: $2,500 per eligible patient per year
• Eligible service types: in-home respite care (required); adult day center programs (optional); facility-based 24-hour respite (optional)
• Billed using GUIDE Respite G-codes (rates specified in Exhibit 17 of the Payment Methodology Paper for PY 2026)
• Participant bills and receives payment; if a Partner Organization furnishes respite services, the participant must pass through the full respite payment to that Partner Organization
• Patient cost-sharing is waived for GUIDE Respite Services

Minimum Contact Frequency by Tier (Billing Implications)

Tier	Minimum Contact Frequency	Billing Implication
Low Complexity Dyad	Quarterly	DCMP billable in non-contact months if quarterly requirement met
Moderate Complexity Dyad	Monthly	Contact-based touchpoint required monthly to bill
High Complexity Dyad	Monthly	Contact-based touchpoint required monthly to bill
Low Complexity Individual	Monthly	Contact-based touchpoint required monthly to bill
Moderate-High Complexity Individual	Twice monthly	Two touchpoints required monthly
RCC Tier	Bimonthly	DCMP billable if bimonthly requirement met

Performance Measurement

CMS evaluates participants on five performance measures:

Measure	Type
Use of High-Risk Medications in Older Adults	Quality
Quality of Life Outcome for People with Neurological Conditions	Patient Experience / Quality
Caregiver Burden	New metric (developed for GUIDE)
Total Per Capita Cost	Cost
Long-Term Nursing Home Stay Rate	Utilization / New metric

Performance data feeds the Performance-Based Adjustment, which modifies the DCMP upward or downward. The PROMIS Scale v1.2 Global Health is collected at initial and annual assessments to support the quality of life measure. The ZBI-22 is collected at initial assessment and with reassessments involving caregiver status changes to support the caregiver burden measure.

Data Infrastructure and Reporting Requirements

Participants submit patient data via the Patient Assessment and Alignment Form (PAAF) through the CMS Health Data Reporting (HDR) application in the CMS.gov Enterprise Portal. PAAFs must be submitted within 60 days of the dementia staging tool administration date. CMS returns a real-time Beneficiary Alignment Notification Report with preliminary tiering and respite eligibility determinations, and issues final determinations through the Beneficiary Alignment Report within 15 business days. The report is updated twice monthly.

Participants receive a monthly Data Dashboard via the Expanded Data Feedback Reporting (eDFR) application providing claims-based utilization data for all aligned patients, updated monthly—a meaningful operational intelligence tool for care management teams.

FHIR endpoint integration (HL7 FHIR Questionnaire Response Resource) is available as an alternative to manual PAAF Excel submission, reducing administrative burden for participants with EHR integration capabilities. All participants must use Certified Electronic Health Record Technology (CEHRT) meeting ONC standards at 42 CFR 414.1305.
