Doctor’s fee or facility fee? This mixes two kinds of price: 89% are doctors' fees and 11% are facility fees paid to a hospital or surgery center. Facility fees are usually far higher, so a wide spread can be the two kinds side by side, not providers charging wildly different amounts. Either way, expect a doctor's fee and a facility fee as separate bills when this is done in a hospital or surgery center. Where a state has both, the table and each state’s popup show the doctor’s fee and the facility fee side by side; their sum is a rough total for the visit, before anything else done during it.
Who is counted: EmblemHealth lists clinicians individually: 98% of the 161,225 provider IDs (NPIs) it names are individual doctors, nurse practitioners and therapists; the rest are practices, clinics and hospitals. “Providers” counts those IDs. EmblemHealth’s files name 43,307 providers for this procedure; 14,884 are counted here: the clinicians whose specialty performs it — mostly Nurse Practitioner, Physician Assistant and Internal Medicine — and the practices, clinics and hospitals. Insurers attach their whole fee schedule to every contracted provider, so the rest are clinicians listed at a price for something they never do; counting them would inflate the provider count and pull the typical price towards the fee schedule’s floor.
Not on this map: Care in New Jersey: for some plans, EmblemHealth rents the QualCare network. Its prices are QualCare's, so they are not included here. Montefiore's doctors and hospitals are missing: the Montefiore file EmblemHealth publishes dates from 2022, is not in the required format, and points to a provider list that is no longer there. These are EmblemHealth's August 2026 files - the newest it had published when this was built. Doctors EmblemHealth pays a flat monthly amount per patient (capitation) have no price per visit. For them its files carry a placeholder of ten cents, marked as a derived amount; those entries are left out, so such doctors may not appear on a map.

“x Medicare” compares each price with what original Medicare pays for the same lab test under its clinical laboratory fee schedule (26CLABQ4, in force from 2026-10-01): one national price, the same in every state. Insurers write their contracts as a share of Medicare, so 1.3x means the insurer pays 30% more than Medicare would; Medicare Advantage plans generally pay close to 1.0x.
This is a statewide summary. Prices vary far more between towns and between practices than these medians suggest; zip-code and provider-level detail is not published here; this specific data can be requested here.
