Analysis: how to think about inhalation of nitrous oxide / anxiolysis costs
The adjunctive category spread for inhalation of nitrous oxide / anxiolysis (CDT D9230) 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 $38 (about 45% of the private rate). Practices in the other 10 states have no Medicaid fee schedule entry for D9230, which is part of why Medicaid-accepting providers can be scarce for this procedure.
