Doctor’s fee or facility fee? These are doctors' (professional) fees only. If this is done in a hospital or surgery center, the facility bills its own fee on top — for the room, nurses and equipment — often larger than the doctor's. That fee is not included here.
Who is counted: CareFirst BlueCross BlueShield lists clinicians individually: 84% of the 99,960 provider IDs (NPIs) it names are individual doctors, nurse practitioners and therapists; the rest are practices, clinics and hospitals. “Providers” counts those IDs. CareFirst BlueCross BlueShield’s files name 99,297 providers for this procedure; 15,892 are counted here: the clinicians whose specialty performs it — mostly Internal Medicine, Family Medicine and Clinic/Center — 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: These prices come from the file set every Blue plan publishes centrally for members of other Blue plans (BlueCard). It may leave out networks the plan publishes only on its own site.

vs Medicare
“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.
