What this code is
This code is for giving a medicine or fluids by injection or through an IV, not for the medicine itself.
Why your hospital bill can show more
Medicare pays a national amount for each code. Hospitals set their own list prices, called the chargemaster, so a hospital bill can show a much higher amount for the same code. In a hospital or an emergency room, a separate facility charge is often added. Medicare's amount is not a price the hospital must accept, but it is a fair reference to negotiate.
Common billing problems with CPT 90471
A separate facility charge
In a hospital, the facility usually bills its own line for the room and staff, and the doctor can bill separately. Ask the hospital to list each part.
No code on the line
If your bill shows a total without codes, ask for a fully itemized bill. Without codes, nobody can check the charges.
How to question this charge
- Ask the hospital for a fully itemized bill, with the code, date, quantity and price of every line.
- Compare the line with the Medicare amount above.
- Ask in writing for a fair price, the lowest amount they will accept, and any discount for paying in full or for patients without insurance.
- Ask for the hospital's financial assistance policy.
