National benchmarks
What this number is — and isn’t
This is the facility fee— what the insurer has contracted to pay the hospital or surgery center for this specific billing code, as published in the insurer’s Transparency in Coverage filing. It covers the technical or facility component of the procedure only. Most care episodes generate additional bills: a separate physician fee (billed under the same CPT as a professional claim), anesthesia, and follow-up care — so an all-in episode total is typically several times this line item. This number is not a patient cost estimate; what you owe depends on your deductible, coinsurance, and the other codes billed.

Methodology
The national median for 27447 is computed using a median-of-state-medians method: within each state we compute the median of all payer-reported in-network rates, then take the median of those state medians. This prevents high-volume states from dominating the national figure.
Cells with fewer than 5 underlying rates are suppressed before aggregation to prevent thin markets from distorting state or national summaries. An institutional billing class means rates reflect the facility fee schedule — what a hospital or ambulatory surgery center bills. The two billing classes are not directly comparable for the same procedure code.
All rates are derived from federally-mandated Transparency in Coverage Machine-Readable Files (45 CFR Part 147). We do not model, estimate, or invent prices — every figure traces back to a payer-published filing. A median is a summary, not a quote. No individual provider necessarily charges the median; percentile ranges exist precisely because prices vary. Verify specifics with your payer or provider. See our full methodology.
Payers contract under different structures (fee schedule, percent of billed charges, case rates); medians that diverge sharply from the national range usually reflect a different payment methodology rather than a genuinely different price.
