Common questions
How much does phosphorus test cost at a hospital?
At 122 hospitals that publish a cash price, the typical price for phosphorus test is $54, and most charge between $9 and $515. The typical rate commercial insurers have negotiated is $10. These are hospital prices; independent clinics, imaging centers and labs often charge less.
Is it cheaper to pay cash or use insurance for phosphorus test?
At 23 of the 115 hospitals that publish both, the cash price is lower than the typical insurer rate. Remember that with insurance you pay only your share of that rate once your deductible is met, and that cash payments usually don't count toward your deductible.
Does the price include the doctor?
No. These are the hospital's own charges, often called the facility fee. The doctors involved, such as the surgeon, the anesthesiologist or the radiologist who reads a scan, usually send a separate bill.
Before you go
- Ask for an estimate. Hospitals must give uninsured and self-pay patients a written good-faith estimate before planned care.
- Check the network. Confirm that the hospital and the doctors are in your plan's network.
- Ask about financial help. Non-profit hospitals must have a financial assistance policy; many discount or forgive bills by income.
- Get an itemized bill. Compare it with the estimate and question anything you don't recognise.
