CMS, HHS, and Louisiana MCOs: Health Policy Changes This Week to Keep an Eye On

Louisiana will pay four private Medicaid plans $16.1 billion in 2027 to absorb the members of two departing insurers, pending legislative approval next month. CMS also added a substance use disorder track to Medicare ACCESS, and ARPA-H opened an autism research program.

Louisiana Medicaid: six plans become four

The Louisiana Department of Health this week presented the Joint Legislative Committee on the Budget with proposed contract extensions for the four managed care organizations that will remain in Healthy Louisiana: Aetna Better Health, AmeriHealth Caritas, Humana Healthy Horizons, and Louisiana Healthcare Connections. Each contract runs between $3.2 billion and $5.8 billion a year. Together they are the largest contracts in state government.

The state began 2026 with six plans. UnitedHealthcare left at the end of March, taking about 278,000 members with it, after a legal dispute with Attorney General Liz Murrill over its affiliated pharmacy benefit manager. On September 1, LDH announced that Healthy Blue, offered by Elevance Health and Blue Cross Blue Shield of Louisiana, will end its Medicaid contract on December 31. Healthy Blue covers roughly 292,000 people.

Total managed care spending still falls, from $16.7 billion in 2026 to $16.1 billion in 2027. Louisiana Medicaid has shed 176,000 enrollees this year, dropping from about 1.5 million in December to 1.3 million in early September. The remaining plans are being paid more because they are taking on more members.

The transition mechanics matter more to providers than the dollar figures:

Healthy Blue members receive notice letters by October 1 and may choose a new plan from October 15 through November 16.

Members who do not choose are auto-assigned. The algorithm keeps families together, favors plans that already contract with a member's current providers, and in some cases gives more members to plans with better performance scores.

For the first 60 days of 2027, the receiving plan must honor services Healthy Blue already authorized, including prescriptions.

Medicare ACCESS adds a substance use disorder track

On September 15, CMS announced that its ACCESS model (Advancing Chronic Care with Effective, Scalable Solutions) will add tracks for heart failure, COPD, substance use disorders, and tobacco cessation starting April 1, 2027. It will also extend musculoskeletal pain support beyond the first 12-month care period.

ACCESS launched July 5, 2026, and runs for ten years. It pays participating organizations for virtual care, health coaching, remote monitoring, and connected devices between regular office visits. The key difference from standard Medicare billing is how payment works. CMS makes recurring “outcome-aligned payments,” and full payment depends on patients reaching measurable health targets.

The SUD track covers opioid, alcohol, and other substance use disorders, with integrated support for co-occurring depression and anxiety. It is part of HHS's Great American Recovery initiative.

The rules for joining are specific. Participants must be Medicare Part B–enrolled organizations with a Medicare-enrolled medical director, and CMS reviews applications on a rolling basis. Only people in Original Medicare are eligible. Medicare Advantage enrollees are excluded, though their plans may offer something similar. The model has 160 participating organizations so far, and CMS says three in four Medicare beneficiaries qualify for at least one track.

The provision that reaches furthest is the payer pledge. Health plans covering 165 million people across Medicare Advantage, Medicaid, and commercial insurance have pledged to adopt outcome-based payment aligned to ACCESS.

ARPA-H launches SPECTRA for autism diagnosis and care

On September 17, the Advanced Research Projects Agency for Health launched SPECTRA (Systems for Phenotypic Evaluation, Clinical Trajectories, Response, and Agency). The program combines biological, clinical, behavioral, and real-world data to make autism diagnosis earlier and more accurate and to match individuals with interventions.

The case for the program starts with prevalence and access. One in 31 U.S. 8-year-olds has been identified with autism spectrum disorder. Diagnosis still relies on time-intensive behavioral observation by trained professionals who are hard to find in much of the country, so it often comes late, after the window when early intervention helps most.

ARPA-H will fund work in four areas: analysis of genetic, environmental, and developmental factors; privacy-preserving AI models of developmental trajectories; precision intervention and testing; and enabling technologies that measure day-to-day function and support communication. Solution summaries for solicitation ARPA-H-SOL-26-163 are due on a staggered schedule, starting with the first technical area on October 18.

The bigger picture

A state consolidating its Medicaid plans, a federal agency tying Medicare payment to outcomes, and a research agency betting on earlier and more precise diagnosis look like separate stories. They share one premise: payers now want fewer intermediaries and clearer proof that care worked. Louisiana will deal with fewer, larger plans with more negotiating power. Medicare is testing whether results can replace visit counts as the basis for payment, and 165 million commercially and publicly insured lives are pledged to follow. The practical consequence for Louisiana providers is the same in each case. Contracts, credentials, and outcome data are becoming the terms of access to patients, and the organizations that get these in order early will have more say in how those terms are set.

Seersucker Strategies tracks each of these through our legislative and regulatory monitoring and will report on the JLCB vote in October.
