Seeing CPT code 94002 on your medical bill?
This code is only one part of the picture — your bill, EOB, insurance adjustments, units, and other charges may affect what you actually owe. MD Bill Check reads the codes on your document, checks the bill in context, and flags items that may be worth reviewing.
What Medicare pays for CPT code 94002
Medicare national average (2025): $87.98
Treat this as a reference point, not a ceiling. It is what Medicare pays nationally before any local adjustment — private insurers negotiate their own rates, and a hospital's list price for the same code is often several times higher. A charge far above this number is not automatically an error, but it is a fair thing to ask about.
How many units of CPT code 94002 should appear on one day
If your bill shows more units of CPT code 94002 for a single date of service than that, it is worth asking the billing office to explain the count — duplicate lines and unit-entry mistakes are among the most common medical-billing errors.

These are 8 of 121 pairs recorded for CPT code 94002. Seeing one of these codes billed alongside CPT code 94002 is not proof of an error — a modifier can legitimately justify it — but it is a specific, answerable question to put to the billing office. What unbundling means, and how to raise it.
