CMS 340B Cut: $4.85B Hospital Shock

🏥 Washington just dropped a $4.85 billion bomb on hospitals.
CMS released it on July 2. Most people are still catching up.

📋 Here is the scene. CMS issued a proposed rule for Calendar Year 2027. On the surface, it looks reasonable. A net 2.4% increase in Medicare hospital outpatient payment rates. A 3.2% market basket update, offset by a 0.8 percentage point productivity cut. Sounds like a raise, right?

🔍 Here is what most people are missing. Buried inside that same rule is a nearly 40% cut to payments for drugs acquired under the 340B Drug Pricing Program. CMS proposes to move reimbursement from ASP plus 6% all the way down to ASP minus 33.4%. According to the American Hospital Association, CMS estimates this reduction will amount to $4.85 billion in CY 2027 alone.

📊 The numbers are stark. CMS would expand site-neutral payment policy to imaging without contrast services in grandfathered off-campus hospital outpatient departments, at a proposed rate of 40% of the outpatient PPS rate. The agency estimates that policy alone cuts outpatient PPS spending by $260 million in CY 2027. And the 340B recoupment pace? CMS proposes to accelerate it by reducing the conversion factor from 0.5% annually to 3% annually, completing recoupment by CY 2029 instead of CY 2041.

⚠️ Here is the implication nobody wants to say out loud. Ashley Thompson, AHA senior vice president of public policy analysis and development, said it plainly: this enormous cut will make drugs less affordable for the most vulnerable patients, many already struggling with higher insurance premiums, loss of healthcare coverage, and skyrocketing drug prices. Hospital outpatient departments disproportionately serve patients with more complex conditions, higher rates of disability, and people from rural or underserved communities. Site-neutral payment policies that ignore those differences do not reduce costs. They reduce access.

💡 At Oatmeal Health, we work every day with the hardest-to-reach populations, people who depend on exactly these safety-net providers. When reimbursement gets squeezed at the margin, care disappears at the front door. This rule is not just a payment policy debate. It is a question about who gets care and who does not.

🎯 Policy that cuts $4.85 billion from the drugs used by the most vulnerable patients is not reform. It is rationing with a press release.

🤔 For the hospital CFOs and outpatient department directors reading this: what is your contingency plan if this rule finalizes as written? Are you modeling the 340B impact on your CY 2027 budget right now, or waiting until August 31 when the comment window closes?
