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 26,325 services.
Of the 4 doctor visits codes on this site with CMS figures, this one has the widest gap between what is billed and what Medicare accepts. The narrowest is Office visit, established patient, level 3 at 2.2x.
Where this line goes wrong
One admitting doctor
Only the admitting physician bills initial hospital care. Other doctors who saw you on day one bill consultations or subsequent care. Two initial care codes for the same day from two doctors is worth a question.
ER visit plus admission by the same doctor
If the same physician saw you in the ER and admitted you, only the admission is billed. An ER level and 99223 from the same doctor on the same day is a duplicate.
