The Uncertain Landscape of Medicare Agent/Broker Compensation Rules

July 11, 2024 | Blog | By Tara E. Dwyer, Xavier Hardy, Madison Castle

In the Proposed Medicare Advantage and Part D Rules for 2025, the Centers for Medicare & Medicaid Services (CMS) proposed significant changes to how Medicare Advantage organizations (MAOs) are allowed to contract with and compensate entities that provide agent/broker and enrollment services.  The proposed rules were heavily disfavored by entities that provide such services, but were not widely commented on by MAOs or Part D sponsors (PDP Sponsors), which are the entities to which the rules actually apply.

Court Split Creates Uncertainty Around Enforcement of the No Surprises Act

June 20, 2024 | Blog | By Cassandra Paolillo, Madison Castle

A recent court split about whether awards granted through arbitration under the No Surprises Act (NSA) are enforceable through litigation has created uncertainty around an already complicated process.  A Texas judge recently held that the NSA does not grant parties a right to bring suit to enforce arbitration awards, while last year a New Jersey court granted enforcement of a similar award.  The resulting split raises questions about the enforceability and utility of the NSA and its Independent Dispute Resolution (IDR) process.

Last month, the National Academies of Science, Engineering, and Medicine (“NASEM”) issued a report discussing the inclusion of pregnant and lactating people in clinical research and the health impacts of inadequate data from research involving this subpopulation. Titled “Advancing Clinical Research with Pregnant and Lactating Persons: Overcoming Real and Perceived Liability Risks,” the report came as a response to Congress calling upon NASEM to examine the real and perceived prevalence of legal liability resulting from including these research subjects in clinical trials. Overall, the report concluded that legal liability for including pregnant and lactating persons in research is very limited, but that perceptions of potential liability and a lack of explicit guidance for including this population safely have created real barriers to their inclusion.  In response, the report provides recommended actions for Congress, the Food and Drug Administration (“FDA”), the National Institutes of Health (“NIH”), and the Office of Human Research Protections (“OHRP”) to take to enhance the inclusion of this population in clinical trials, thereby enhancing data around the safety and efficacy of approved drug products for pregnant and lactating persons.  Study sponsors and institutions conducting research should continue to monitor developments in this area, including guidance from FDA.

Unpacking CMS’s 2025 DSNP Changes: Considerations for Medicare Advantage Organizations

May 1, 2024 | Blog | By Tara E. Dwyer, Lauren Moldawer, Madison Castle

As part of its 2025 Medicare Advantage and Part D Final Rule (the Final Rule), the Centers for Medicare & Medicaid Services (CMS) made a number of enrollment changes impacting dual eligible special needs plans (DSNPs). The goal of these changes is to promote integration of Medicaid and Medicare services for full benefit dually eligible (FBDE) individuals. While stakeholders support the overall goal of better integration, the new policies are complex and may discourage Medicare Advantage Organizations (MAOs) from participating in Medicaid managed care programs in certain regions. They also highlight how a federal DSNP regulation that is tied to how a state contracts with entities that offer Medicaid benefits can result in different impacts in different states.

CMS Releases Part Two of Guidance for the Inflation Reduction Act’s Medicare Prescription Payment Plan

February 27, 2024 | Blog | By Tara E. Dwyer, Lauren Moldawer, Madison Castle

On February 15, 2024, the Centers for Medicare and Medicaid Services (CMS) released the Medicare Prescription Payment Plan Draft Part Two Guidance (Part Two Guidance) as part of the Inflation Reduction Act’s (IRA) efforts to tackle high prescription drug costs. The Medicare Prescription Payment Part Plan (the Program), which was previously referred to as the “OOP Smoothing Program”, was established as part of the IRA and requires Part D plans (PDPs) to offer their members an option to pay for out-of-pocket (OOP) prescription drug costs in monthly capped payments, as opposed to all at once, at a pharmacy. Meaning, for members who opt-in to the Program, they will pay $0 at the pharmacy and the PDP must pay the pharmacy the full cost-sharing amount of the drug and then bill the member the amount of the cost-sharing over the remainder of the calendar year.
