Seeing CPT code 95811 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 95811
Medicare national average (2025): $637.23
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 95811 should appear on one day
If your bill shows more units of CPT code 95811 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.
Codes normally billed as one with CPT code 95811
Medicare's National Correct Coding Initiative (NCCI) publishes pairs of codes that are considered a single service when performed together. Billing them separately — "unbundling" — inflates a bill.
| Paired code | How the pair is normally treated |
|---|---|
| 93000 Cardiac test | Separately payable only when a modifier documents a genuinely distinct service |
| 93005 Cardiac test | Separately payable only when a modifier documents a genuinely distinct service |
| 95810 Diagnostic test | Not separately payable — the pair is expected to be billed as one service |
| 95816 Diagnostic test | Not separately payable — the pair is expected to be billed as one service |
| 93010 Cardiac test | Separately payable only when a modifier documents a genuinely distinct service |
| 93224 Cardiac test | Separately payable only when a modifier documents a genuinely distinct service |
| 95819 Diagnostic test | Not separately payable — the pair is expected to be billed as one service |
| 95910 Diagnostic test | Separately payable only when a modifier documents a genuinely distinct service |
Seeing one of these codes billed alongside CPT code 95811 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.
