For decades, the narrowly defined Emergency Medicaid (EM) program has reimbursed hospitals for emergency care provided to uninsured, low-income immigrants. In @nejm.org, we write in defense of state flexibilities in EM, which seem at risk: www.nejm.org/doi/full/10.... cc @chpc-cornell.bsky.social

Not great apples-to-apples estimates out there, but roughly my sense is rx is comparable, ED in Medicaid is higher, outpatient care in Medicaid is lower.

2. The OBBBA includes work requirement exemptions for certain groups, including folks who are "medically frail" or in treatment for SUD. Our paper is an early proof-of-concept that states could use claims to automate exemptions (if allowed to do so in final regs). 5/N

William Schpero @wschpero.bsky.social · 18/09/2025
➡️ We see two important implications: 1. Most expansion enrollees are actively receiving care. The coverage losses predicted under the OBBBA's work requirement will thus likely introduce discontinuities in care. 4/N
131
William Schpero @wschpero.bsky.social · 18/09/2025
➡️ Key Finding 2: There was meaningful variation in health care use across states. Rx use exhibited the largest variation across states, followed by outpatient visits, ED visits, and inpatient visits. 3/N

William Schpero @wschpero.bsky.social · 18/09/2025
