Sleep study cost in Maryland
No plan has filed Polysomnography, attended in Cambridge, MD in a form we can read, so this page shows Maryland instead and says so. These are the rates plans published under federal law. Not billed charges, and nothing here is scaled, adjusted or estimated to stand in for the market we do not hold.

Reading it
What this distribution actually says.
The spread
The middle half of this market runs from $190 to $759, a 4.0x difference for the same procedure code in the same city. That gap is between contracts, not between quality.
Against Medicare
Medicare pays $681 for this service at its Rest Of Maryland locality. We do not turn that into a percentage here, because the price above is Maryland and that Medicare figure is one locality inside it. Two different maps do not divide.
The expensive end
One in ten filings sits at or above $1,090. If a plan's network is weighted toward that end, the difference does not show up in a premium quote. It shows up in the claims.
How wide the data runs
The carriers that filed for this procedure in this market. What each plan has agreed to pay, side by side. These are prices, not bills, so they do not show how often anyone needs it.

Every figure on this page carries its source, its scope and the date the corpus was built, so it survives being forwarded to someone who was not in the meeting.
