The gap
4.5x
How many times the accepted amount the billed figure was.
National averages from the Centers for Medicare & Medicaid Services, 2024 data, retrieved 2026-09-14. Medicare fee-for-service, physician and practitioner claims only. The hospital's own charge for the same code is separate and is usually higher. Based on 5,269 services.
Among the 10 lab tests codes on this site with CMS figures, this gap ranks 2 of 10 (median 3.7x). The widest is Urinalysis, automated with microscopy at 5.5x.
Where this line goes wrong
Never alongside 80053
The comprehensive panel includes every test in this one. Both codes on the same sample is a coding error.
Components
Individual tests like glucose (82947) or potassium (84132) billed on top of the panel from the same draw are duplicates.

People also ask
Why was I charged for a metabolic panel and a glucose test?
If both came from the same blood draw, the glucose is already in the panel and should not be billed again. Ask for it to be removed.

Whether a charge was correct depends on the record of your visit and your payer's rules.
