Analysis: how to think about amalgam - one surface (permanent) costs
The restorative category spread for amalgam - one surface (permanent) (CDT D2140) runs 36% between the cheapest and priciest states in our 2024 dataset, and cost of living explains most of that gap, not procedure difficulty.
40 of 50 states reimburse adult Medicaid patients for this code, averaging $75 (about 44% of the private rate). Practices in the other 10 states have no Medicaid fee schedule entry for D2140, which is part of why Medicaid-accepting providers can be scarce for this procedure.
