Doctor’s fee or facility fee? These are the emergency doctor's fees only. The hospital bills its own emergency-room facility fee on top, usually several times larger, and it is not included here.
Who is counted: Mass General Brigham Health Plan mostly lists practices, not individual clinicians: 87% of the 5,559 provider IDs (NPIs) it names belong to a practice, clinic or hospital, which stands for everyone who works there. So “providers” here mostly counts practices — one entry can cover many doctors — and is not comparable with insurers that list each clinician. Mass General Brigham Health Plan’s files name 3,922 providers for this procedure; 750 are counted here: the clinicians whose specialty performs it — mostly Clinic/Center, Family Medicine and Nurse Practitioner — 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: Mental health care: Mass General Brigham Health Plan rents Optum's national behavioral health network. Its prices are Optum's, set nationwide, so they are not included here. Care outside New England: for some plans it rents UnitedHealthcare's and MultiPlan's national networks. Those prices are not included here. Hospital stays: Mass General Brigham Health Plan's files have no prices for whole hospital stays (the kind billed as one amount per stay), so there are no hospital-stay maps for it. It may pay hospitals by the day or as a share of their charges, which these maps cannot show.

vs Medicare
“x Medicare” compares each price with what original Medicare pays a doctor for the same service in the same state under its physician fee schedule (RVU26D, in force from 2026-10-01) — the lower price a doctor is paid when a hospital or surgery center provides the room and equipment. 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.
