Medicare Drug Price Negotiations Again Target High-Impact Prescriptions, But at what Cost?

By: Marcus J. Hopkins, Health Policy Lead Consultant, ADAP Advocacy

The Trump Administration recently released the next round of medications selected for the Medicare Drug Price Negotiation Program, which includes 15 medications payable under Medicare Part B and/or covered under Medicare Part D, largely for the treatment of chronic diseases and cancer.

Of greatest concern to ADAP Advocacy is the inclusion of Biktarvy, the most commonly prescribed single-pill oral regimen to treat HIV made by Gilead Sciences, currently taken by over 430,000 people living with HIV in the United States (Gilead Sciences, 2026), or 35.8% of People Living With HIV/AIDS (PLWHA).

In June 2025, ADAP Advocacy submitted public comment to the Centers for Medicare and Medicaid Services (CMS). In this public comment, it requested that CMS create a carve-out exemption for all medications used for the treatment of HIV/AIDS in order to avoid any interruptions of service for PLWHA who rely upon Medicare for their HIV medications.

ADAP Advocacy followed up on this public comment with a sign-on letter to CMS requesting the carve-out exemption, which garnered signatures from nearly 40 organizations and received a direct response from Dr. Mehmet Oz, the current CMS Administrator.

The response?

"CMS acknowledges your recommendation to implement a carve-out exemption for all medications indicated for the treatment and prevention of HIV/AIDS; however, the statute does not specify a specific exclusion for medications used for the treatment of HIV/AIDS from selection under the Negotiation Program."

Essentially, “Sorry. Can’t help you.”

What Does Price Negotiation Mean?

As ADAP Advocacy detailed in a July 2025 blog, Medicare’s Negotiation Program essentially requires manufacturers to accept the final price after four negotiation meetings set by CMS, reject the offer, and pay a 95% excise tax on all of the medications sold to Medicare payors, or remove their products from the Medicare formularies altogether (Hammond, 2024). Because no business can feasibly accept a 95% excise tax and remain viable, manufacturers are left with the unenviable decision to either accept significant profit losses in the Medicare market or withdraw their drugs (Hopkins, 2025). This process, which is supposed to resemble a negotiation, has been characterized by many as a threat with the full force of the federal government behind it. One public health stakeholder attending ADAP Advocacy’s Health Fireside Chat last year in Minneapolis, Minnesota, called it extortion. 

For PLWHA, the inclusion of one of the most effective single-pill regimens in the history of HIV treatment on this list presents a real and present danger should Gilead Sciences determine that allowing Biktarvy to be purchased at a significant loss by Medicare payors is unacceptable.

Medicare is the 2nd-largest payor of HIV treatment and care in the United States, accounting for 39% of federal spending in 2020, and serving 28% of PLWHA (Dawson, et al., 2023).

Patient advocates continue to share their concerns over Biktarvy, or any other HIV-related product, being targeted by CMS for artificial government price controls. Among them is Aging and HIV Institute’s David “Jax” Kelly, JD, MPH, MBA. Kelly argued, “Nearly 28% of PLWH in the United States are Medicare beneficiaries, and most qualified through disability rather than age… [t]his unique cost profile reflects both the effectiveness and the financial burden of HIV treatment. Interruptions in ART jeopardize not only individual health but also public health goals. Sustained viral suppression—essential to ending the epidemic—depends on reliable, affordable access to medications.”

ADAP Advocacy will follow up with its aforementioned communications with CMS by submitting public comments in response to its request for information about selected drugs and their therapeutic alternatives, because the inclusion of an antiretroviral therapeutic “is playing with fire,” as ADAP Advocacy’s CEO has noted on numerous occasions.

What Can Patients Do?

Please find information below on how you can get involved:

[From CMS]:

The Negotiation Program enables Medicare to directly negotiate the prices of certain high-cost drugs. The current cycle of negotiation and renegotiation is underway, and CMS wants to hear directly from patients, caregivers, clinicians, and others to gather input relevant to the selected drugs.

CMS invites you to rally the communities you represent to share information about the public engagement events, including a virtual livestreamed town hall meeting focused on the clinical considerations related to the selected drugs, and private (i.e., not livestreamed or open to press or general public) virtual patient-focused roundtable events, one for each selected drug, for patients, patient advocacy organizations, and caregivers.  

Take Action

• Learn more about the drugs selected for the current cycle of negotiation and renegotiation here.
• Use communication tools available here so that your organization can leverage your various communication channels to share information about these opportunities:
• Complete the Drug Price Negotiation Information Collection Request (ICR).
• Register for public engagement events here. 

Key Dates

• The Drug Price Negotiation ICR is now available, and responses are due by March 1, 2026. It is worth noting that for patients wanting to submit public comments, questions 28-33 are the patient- or caregiver-focused input (so don’t get overwhelmed by the length of the online form)
• Drugs selected for the upcoming cycle of negotiation and renegotiation were announced on January 27, 2026, and registration for the public engagement events is open now until March 6, 2026.
• Public engagement events for Biktarvy include:
• Roundtable event on Monday, April 6 from 2:30 – 4:30 p.m. ET 
• Town Hall Meeting on Wednesday, April 22, Session 1 from 10:30 a.m. – 12 p.m. ET

Registration for the opportunity to speak at the public engagement events is now open and will close at 11:59 p.m. PT on March 6, 2026.

ADAP Advocacy urges patients and patient advocates to weigh in. While financial outlays may be high for PLWHA due to treatment costs, the financial impacts of treatment interruption are far higher. While treatment cessation for any disease state can cause serious complications, the nature of the HIV retrovirus is such that it can quickly mutate to develop resistance to a treatment regimen if that regimen is suddenly halted. This can create a strain of HIV that is multidrug-resistant (MDR-HIV), making the virus more difficult and significantly costlier to treat–and result in premature death. CMS targeting an HIV-related therapeutic signals a threat to AIDS exceptionalism, and it cannot be left to chance.
