Humana Expands In-Home Kidney Care Amid MA Headwinds
Summary: Humana and Monogram Health are expanding their in-home kidney care program to Georgia, building on their existing partnership in Alabama, Louisiana, Mississippi, and Tennessee. This move aims to provide earlier interventions for eligible Medicare Advantage members with chronic kidney disease (CKD) and end-stage kidney disease (ESKD), particularly in underserved areas. The expansion aligns with Humana’s broader push into value-based care (VBC), as detailed in its 11th annual VBC report. The report underscores the role of Medicare Advantage in accelerating VBC adoption, highlighting improved outcomes, reduced hospitalizations, and financial incentives for providers. Humana continues to advocate for expanding VBC into Medicaid, emphasizing its potential to enhance chronic disease management and health equity. We covered Humana’s value-based kidney care report last year, which at the time had impacted over 77,000 patients nationwide, with notable improvements in unnecessary hospital admissions, MER, and rates of nephrology follow-up visits.1
Thoughts: Humana’s expansion with Monogram comes as the insurer navigates financial and operational headwinds, including a projected 10% decline in Medicare Advantage (MA) membership in 2025 (~550,000 members) and the impact of lower Star Ratings on future bonus payments. Despite these challenges, Humana continues to bet on value-based care (VBC) and in-home polychronic care as part of its long-term strategy. Its latest earnings call highlighted a focus on managing medical spending, improving patient and provider engagement, and driving profitable growth—all areas where home-based kidney care could play a role. Meanwhile, CMS’s first-year Kidney Care Choices (KCC) evaluation showed mixed-positive results, reinforcing the complexities of managing CKD and ESRD populations under risk-based models. As Humana and others double down on MA-driven VBC, the key question remains: Can these models scale effectively and deliver sustained improvements in cost and care outcomes?2
What do you think? What do people not know or misunderstand about Medicare Advantage, public or private ESRD costs that they should?3
FDA Approves First Xenotransplant Trials for Kidney Patients

Summary: The FDA has approved clinical trials for two biotech companies, United Therapeutics and eGenesis, to transplant genetically modified pig kidneys into patients with kidney failure. United Therapeutics will begin with six patients, potentially expanding to 50, while eGenesis will start with three patients who are unlikely to receive a human kidney within five years. These trials mark a major step toward xenotransplantation, which could help address the severe organ shortage—nearly 100,000 Americans are currently on the kidney transplant waitlist. However, questions remain about long-term safety, immune response, biosecurity, and ethical concerns. Meanwhile, the fourth xenotransplant just took place, with Tim Andrews, a 66-year-old dialysis patient, receiving a pig kidney at Massachusetts General Hospital. His transplant team shared that Andrews had just a 9% chance of receiving a human kidney in the next five years and a nearly 50% chance of being removed from the waitlist due to declining health.
Thoughts: Xenotransplantation is moving from experimental surgeries to structured clinical trials, and the implications are massive. If these trials prove successful, we could be on the verge of a major shift in organ availability. But will it be enough? Many in the kidney community remain skeptical that “xeno” alone will meaningfully reduce the transplant waitlist in the near future. In my recent poll, nearly half of respondents predicted the waitlist would be longer in 10 years than it is today. Even with advancements in xenotransplantation, bioengineering, and donor incentives, rising rates of diabetes, hypertension, and kidney disease could outpace these innovations. The reality is that no single breakthrough will solve the organ shortage—it will take a combination of new therapies, better prevention, and systemic policy changes.
What is you biggest hope for transplant by the end of 2025?
Visual of the Week
Kidney Transplant Waitlist Size, 2016 to Present. After years of decline, the kidney transplant waitlist has started growing again. This chart tracks the total number of people on the waitlist on each day over time, with key policy changes and the onset of COVID-19 marked by vertical lines. The newest kidney allocation policy (“KAS250”) broadened geographic distribution while increasing allocation system complexity.4 The long-term downward trend reversed in 2022, and the waitlist has been steadily climbing ever since.
Recent discussions in the kidney community reflect uncertainty about where this trend is headed. In my latest poll, nearly half of respondents predicted the waitlist will be longer in 10 years than it is today. While some see hope in xenotransplantation, organ bioengineering, and living donor incentives, others believe rising rates of kidney disease and systemic barriers to transplantation will outweigh these innovations.
What do you think—will the waitlist be longer or shorter in 2035? What factors will make the biggest impact?

There is a lot of discussion in the Dialysis space regarding Medicare advantage. Medicare advantage impacts independent Dialysis providers the most. Medicare advantage is heavily marketed to patients and patients are able to enroll on a quarterly basis. Some of the potential benefits marketed to patients is often misleading. For example, Medicare advantage plans will promise covered services, such as transportation, but transportation to dialysis is not included.
Patients are told that joining a Medicare advantage plan will not require a change of dialysis provider, but the plan rarely shows the inpatient Dialysis and Nephrology providers when marketing and selling Medicare advantage plans. Medicare advantage is also not transparent regarding patients on dialysis maximum out-of-pocket cost that they are responsible for covering.
When a traditional Medicare patient changes to a Medicare advantage plan they’re permitted to keep their Medigap secondary insurance coverage. However the Dialysis space has seen that most Medicare advantage plans advise against keeping the patients Medigap insurance. Some of the information presented to the patient advises against keeping the Medigap insurance telling patients they’re better off, directing those dollars through their out-of-pocket expenses
If the patient chooses to return to traditional Medicare, the patient must undergo underwriting, which is different in each state, to reinstate or acquire their Medigap policy. There are other multiple aspects of Medicare advantage that do not benefit the dialysis patient and provider, but too much to put here.
