Seeing CPT code 99213 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 99213
| Where the service is performed | Medicare national average (2025) |
|---|---|
| Doctor's office or clinic (non-facility) | $88.95 |
| Hospital or facility | $63.72 |
The same code pays two different amounts because a facility bills its own separate charge for the room, staff, and equipment — so a hospital visit can produce two lines where an office visit produces one.
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 99213 should appear on one day
If your bill shows more units of CPT code 99213 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 99213
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 |
|---|---|
| 00100 Anesthesia | Not separately payable — the pair is expected to be billed as one service |
| 00160 Anesthesia | Not separately payable — the pair is expected to be billed as one service |
| 10060 Procedure | Separately payable only when a modifier documents a genuinely distinct service |
| 10061 Procedure | Separately payable only when a modifier documents a genuinely distinct service |
| 11606 Surgery | Separately payable only when a modifier documents a genuinely distinct service |
| 19120 Surgery | Separately payable only when a modifier documents a genuinely distinct service |
| 90460 Vaccine | Separately payable only when a modifier documents a genuinely distinct service |

These are 8 of 136 pairs recorded for CPT code 99213. Seeing one of these codes billed alongside CPT code 99213 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.
