Use this when the user asks what changed, or when a change took effect, in a US public dental program: Medicaid dental fee schedule updates and rate changes, or the start date of an adult Medicaid annual dental cap. Returns adopted changes with their effective date, verbatim quote or data file and source URL, filterable by state and by date range (YYYY-MM-DD); the Texas rate change of September 2026 lists its codes when state is TX. A state without dated tracking returns not_yet_tracked, never a claim that nothing changed. Phrasings: "what changed in Texas Medicaid dental reimbursement this fall", "since when does Colorado cap adult Medicaid dental benefits", "¿qué cambió en el Medicaid dental de Nevada en 2026?", "¿desde cuándo hay un límite anual dental en Medicaid de Massachusetts?". Do not use for: diagnosis, treatment choice, a named insurer's plan price, dentist recommendations, countries other than the US and Canada. Observed market research with a source URL and period on every figure; not a quote, not medical advice.
