New York spent $7,379 per enrollee on these claims in 2024, against $3,239 in California and $5,464 in Texas. Some of the gap is real program generosity: New York's Medicaid covers more home care and personal assistance services than almost any state, and those services bill through exactly the codes this dataset captures.
Read the Texas line carefully. Its jump from $1,607 in 2020 to $4,382 in 2021 is too fast to be a real spending change. States improved their T-MSIS managed care encounter reporting over this window, so part of every state's growth, and most of that Texas jump, is more complete data rather than more spending.
What this measures: Medicaid and CHIP paid amounts on outpatient and professional claim lines carrying a HCPCS procedure code, attributed to states by the billing provider's practice location in the NPPES registry. It excludes institutional per-diem claims, most pharmacy billing, and payments that could not be tied to a valid billing NPI, so it is a large subset of Medicaid spending rather than the whole program.
