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.

Frequently Asked Questions

What is the average negotiated rate for CPT 27447?

The national median negotiated rate for CPT 27447 (Total knee arthroplasty) is $4,544, computed from 791 rates across 17 payers and 56 states and territories. Individual payer medians range from $1,576 (CareFirst BlueCross BlueShield) to $21,790 (Blue Cross Blue Shield of Wyoming). A median is a summary — your actual contracted rate depends on your specific payer and state.

Why do rates for CPT 27447 vary 13.8× between payers?

Negotiated rates are set individually between each payer and each provider network, so payer-level medians reflect different provider mixes, contract vintages, and market leverage. For CPT 27447, the top payer median ($21,790, Blue Cross Blue Shield of Wyoming) is 13.8× the bottom payer median ($1,576, CareFirst BlueCross BlueShield). Percent-of-charge and per-diem contract structures can also inflate or deflate MRF-derived figures; see our methodology for details.

What does the institutional rate for CPT 27447 cover?

An institutional rate applies when CPT 27447 is billed under a facility fee schedule — typically by a hospital or ambulatory surgery center, not an individual clinician. The $4,544 national median reflects the facility component of the procedure. Patients may also receive a separate professional (clinician) bill. The institutional rate is filed under the insurer's facility in-network MRF and is distinct from the professional rate for the same procedure code.
