📉 Currently, data for real time prescription benefit (RTPB) tools are constrained in the PBM-insurer network. We compared savings through MCCPD to RTPBs studied by Desai et al. (JAMA IM, 2022). Savings through cost plus drugs was substantially greater.

HHS has advocated for adding DTC cash prices to Real-Time Prescription Benefit tools—the software doctors use to check your copay before writing a script. Our study shows what this might do.

Where did we see these massive price gaps? Most were in areas where medications are critical to survival and long-term well-being • Oncology • Psychiatry • Neurology • Cardiology • Transplant medicine

When copays get high, the savings become massive. For prescriptions where insurance copays or coinsurance exceeded $100, the median price patients paid was $140. The median price for those exact same drugs through @costplusdrugs.com? Just $25.

"Does MCCPD even carry these drugs? What about shipping costs?" 97% of prescriptions were available via @costplusdrugs. Even after adding a $5.25 shipping fee—conservative since patients can bundle scripts— 80% of scripts with copays >$15 were cheaper through MCCPD.

If your employer-sponsored insurance copay for a generic is over $15, then 80% of the time, you are overpaying. In @annalsofim.bsky.social , we analyzed nationwide data on employer plans vs @mcuban.bsky.social @costplusdrugs.com Here is a breakdown on who stands to save most. 🧵

According to MedPAC, details of the Part D redesign mean that some enrollees will hit their $2,000 OOP maximum much faster than I realized. In one example, they show how one could hit the max with just $470 in spending.

If you are downloading data right now - I recommend asdfree.com. Anthony Damico has R scripts to download ~50 public surveys, create the survey design and save them locally. If you are an R user this will things go much faster!

HHS announces the next 15 drugs to negotiate under Part D! Great to see this progress. Quite a few cancer treatments, which will mean more savings potential than in the first year's drug list (cancer drugs get limited or no rebates today). Good news for taxpayers and Medicare spending!

It was a pleasure to write this piece for Health Affairs on risk adjustment in Medicare. Risk adjustment modifies payments to health plans or ACOs based on patient/beneficiary characteristics. Here's a very brief summary of my thoughts🧵 www.healthaffairs.org/doi/abs/10.1...
