SANTA ROSA, CA ASSAY OF THYROID STIMULATING HORMONE TSH |
$155.12 | $277.00 | 44% | — file |
Outpatient: lowest $52.50, median $136.68, highest $155.12 — a 3.0× difference within the same market.
As an inpatient, the same code is billed by 4 facilities here, median $137.70. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.
They are priced below $1 or below a tenth of the national median for code 84443 ($83.07). Such a line is almost always a physician's fee billed separately, an assistant's share or a placeholder — a real charge, but not the price of the procedure itself.
