When my wife was pregnant, her OBGYN was very expensive (temporarily) as they just started with the new 3rd party billing company and weren't giving discounts to cash patients. (that's not so common, and apparently a few months later their billing practices were back to normal) United Refuah has limits how much they're willing to get "ripped off" (generally up to 150% of what Medicare pays for the same service codes, but for childbirth they have specific maximums, I'll post soon).
So they advised us to either explore using a different provider, or see how much it'd cost to get a proper insurance plan on the NYS marketplace and they'd pay the premium meanwhile - saving us all that extra money. Hashgach Protis - when I put our info into the NYS application - they put my wife on Medicaid for free - because she was pregnant - even though we were higher than the limit for pregnant women, so I cancelled United Refuah for her,,,
