Samsung is bringing Lark Health’s AI-powered diabetes-prevention coaching into Samsung Health for eligible people in the United States who are 65 or older. The collaboration begins with access to Lark’s Medicare Diabetes Prevention Program, while a separate one-year prevention program may be offered to older Samsung Health users who do not qualify for the Medicare benefit.
The announcement, published October 26, 2026, is less universal than the words “free AI health coach” might suggest. Access depends on age, location, Medicare coverage and medical eligibility. Samsung also says the rollout is phased, with more precise availability details to come as each program launches.
What Samsung and Lark are launching
Samsung Health will act as the entry point for Lark’s digital coaching programs. Lark says its smartphone service uses conversational AI, interactive lessons and health tracking to provide around-the-clock guidance on nutrition, physical activity, sleep and stress. Eligible Medicare participants can also receive live clinical resources and a cellular-connected scale.
The first Medicare pathway is Lark’s Medicare Diabetes Prevention Program, or MDPP. It is intended for people at elevated risk of developing type 2 diabetes, not people who already have an active diabetes diagnosis. Samsung describes the integration as the first stage of a broader plan that could later add support for cardiometabolic and behavioral-health conditions.
Samsung says Lark has served 2.5 million patients. That figure and the claimed benefits come from the companies; Gadget N Widget has not independently tested the coaching, verified outcomes from this specific Samsung integration or evaluated how consistently its AI responds to individual users.
Who may qualify for the Medicare program
The Samsung announcement highlights three basic conditions: the user must be at least 65, have Medicare Part B and not have an active diabetes diagnosis. The full federal eligibility rules are more detailed.
According to the Centers for Medicare & Medicaid Services, a Medicare Diabetes Prevention Program participant generally needs a qualifying blood-test result showing prediabetes within the previous 12 months. CMS also specifies a body-mass-index threshold—at least 25 for most people or 23 for people who self-identify as Asian—and excludes people with a previous diagnosis of type 1 or type 2 diabetes, apart from gestational diabetes. People with end-stage renal disease are also ineligible.
Those rules mean downloading Samsung Health or owning a Galaxy device does not automatically unlock Medicare-covered coaching. A user may need records that establish eligibility, and the program itself—not a phone or watch—determines whether the requirements are met.
There is a second route for some people who do not qualify
Samsung Health users aged 65 and older who do not meet MDPP requirements may instead be offered Lark Prevention. Samsung describes it as a separate one-year wellness and prevention program with an annual value of $249, offered without additional out-of-pocket cost during the companies’ agreement.
This route may be useful for older adults who want habit-building guidance but fall outside the Medicare program’s clinical criteria. However, Samsung and Lark reserve the right to introduce fees or change pricing later. The announcement also does not promise that every otherwise eligible Samsung Health user will see the offer immediately.
Availability requires an internet connection, and Samsung says service may vary or pause when connectivity is poor. The companies have not yet provided a complete list of compatible Galaxy phones, required Samsung Health versions or a state-by-state launch timetable.
AI coaching is support, not diagnosis or emergency care
Lark’s software is designed to encourage healthier routines and help users track progress. It should not be confused with a diagnostic system, a replacement for a clinician or an emergency service. A chatbot cannot confirm diabetes, change prescriptions or evaluate urgent symptoms.
Users should discuss major changes in diet, exercise or weight-management plans with an appropriate healthcare professional, especially when they take glucose-lowering medicine, have mobility limits or manage multiple conditions. Any result or suggestion that conflicts with a clinician’s instructions deserves human review.
The distinction matters because Samsung Health already collects data from phones and optional wearables. More data can make coaching feel personal, but personalization is not the same as a medical judgment. People should review permissions, connected-device settings and privacy information before linking health data or enrolling in a program.
What comes next through Medicare ACCESS
Samsung and Lark plan to expand beyond prevention through the federal ACCESS model, short for Advancing Chronic Care with Effective, Scalable Solutions. CMS says the voluntary model began July 5, 2026, and is intended to test outcome-based payment for technology-supported care in Original Medicare.
ACCESS focuses on common conditions including diabetes, high blood pressure, chronic musculoskeletal pain and depression. Under Samsung and Lark’s plan, future eligible users may receive AI coaching alongside clinical oversight, ongoing tracking and other care resources. Lark’s earlier partnership announcement also discussed connected devices such as blood-pressure cuffs and glucose meters for qualifying programs.
Those future services should not be treated as generally available yet. Samsung’s October announcement uses cautious wording—users “may” gain access—and says additional eligibility and launch information will arrive as the programs become available.
Why this integration matters
Digital prevention programs often struggle with discovery and enrollment. Placing a program inside a health app already present on many Galaxy phones could reduce those barriers for some older adults. It could also connect information from daily tracking with structured coaching instead of leaving step counts, sleep records and other measurements isolated in an app.
The potential tradeoff is that healthcare guidance becomes more tightly connected to a consumer-device ecosystem. A person may have to navigate Samsung, Lark and Medicare rules at the same time. Clear explanations of which company stores each type of information, what clinicians can see and how a user can leave the program will be important as enrollment expands.
Independent reporting from SamMobile confirms the core U.S. eligibility and no-extra-cost details, but the story still rests mainly on announcements from Samsung and Lark. There are no published results yet for the newly integrated Samsung Health experience.
What interested users should do
People aged 65 and older in the United States can keep Samsung Health updated and watch for an eligibility or enrollment option. Before enrolling, it is worth checking Medicare Part B status, locating recent laboratory results and reading the program’s privacy terms.
Anyone who already has type 1 or type 2 diabetes should not expect to qualify for MDPP, which is a prevention benefit. Future ACCESS-backed services may address diagnosed chronic conditions, but Samsung has not supplied a firm consumer launch date for those programs.
Users who do not qualify for the Medicare pathway can look for the separate Lark Prevention offer, while remembering that free access lasts only for the duration of the companies’ agreement. No one should pay a third party merely to “unlock” the announced benefit without first confirming eligibility through Samsung Health, Lark or Medicare.
The practical takeaway
Samsung Health is becoming a doorway to formal prevention services rather than merely a dashboard for fitness data. For eligible older adults, the Lark partnership could provide structured coaching and connected tools without another out-of-pocket charge.
But the launch has strict boundaries: it is U.S.-focused, starts with users aged 65 and older, depends on program eligibility and is rolling out in phases. The AI coach can support everyday habits; it does not diagnose disease or replace a medical professional.
