Insurer prices not shown for this procedure

This hospital’s published rates for this billing code don’t look like a per-visit price — they appear to be a full-stay total filed under an hourly code — so we’re not showing a per-insurer breakdown we can’t stand behind. The fair price above is your best reference; call the hospital’s billing office to confirm the actual charge.

Self-Pay How to get the cash price

Tell the billing desk you want to be billed as self-pay — not through insurance — before your visit.
Ask for the cash / prompt-pay discount in writing, with the exact price (about 103), before you agree to anything.
Get it in writing that they won’t also bill your insurance, so the cash price is what you owe.
Check the HCPCS code on your bill matches exactly: G0378.

Insurance Before you use insurance

Call your insurance company to confirm Marshfield Medical Center is in-network.
Ask your insurer whether prior approval is required for HCPCS code G0378.
Confirm the doctor or provider is in-network too — not just the hospital building.
Check your Explanation of Benefits against the hospital’s final itemized bill.
