Hospital bill errors: what to look for on each line
The errors and questions that matter on a hospital bill: duplicates, unbundled panels, two initial injections, dates outside your stay, everyday items and the arithmetic.
Check my bill freeThe same line twice
The same code on the same day at the same price. Some repeats are real, such as a second blood sample, the other side of the body, or the mother and the baby. Ask for the time and the reason of each one. Imaging and emergency visit levels rarely happen twice in one day.
A test billed on top of its panel
A panel, such as a comprehensive metabolic panel, already includes its single tests. If the same bill lists one of them again on the same day, ask them to remove it, unless it came from a separate draw.
Two "initial" injections or infusions
Medicare coding rules allow one initial injection or infusion per visit, unless two separate IV sites were needed. Each additional drug or hour has its own code.
Two emergency visit levels
One emergency visit normally has one level. If you see two, ask whether one is the hospital fee and the other the doctor fee.
Charges outside your stay
A line dated before you arrived or after you left needs an explanation.
Everyday items billed on their own
Tissues, gloves or a toothbrush are often included in the room or visit charge. Ask why they are billed separately.
The arithmetic
Add the lines and compare with the total, then subtract payments and adjustments and compare with what you are asked to pay. A gap can be a missing page or an error.
