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 10,685 services.
Among the 10 lab tests codes on this site with CMS figures, this gap ranks 4 of 10 (median 3.7x). The widest is Urinalysis, automated with microscopy at 5.5x.
Where this line goes wrong
With and without on the same draw
85025 includes everything in 85027. Both billed together is a duplicate.
Manual differential on top
A manual differential (85007) is sometimes legitimately added when the automated count flags something, but it should have its own result in the lab report.

Red cells, white cells, platelets and haemoglobin, plus the proportions of each white cell type. It is a general screening test rather than a test for one condition.

It is not a coding, legal or medical opinion about your bill, and the code descriptions are mediloop's own plain-English summaries, not the official CPT descriptors, which are owned by the American Medical Association. Whether a charge was correct depends on the record of your visit and your payer's rules.
