CPT 77067: screening mammogram, both breasts. What Medicare pays and what to ask
Whether a mammogram is coded as screening or diagnostic can change what you owe. Here is what 77067 covers and the Medicare rate.
What this code means
CPT 77067 is a screening mammogram of both breasts, usually two views of each, including computer-aided detection when used. A 3D tomosynthesis add-on is billed with 77063.
A diagnostic mammogram, done to look into a symptom or an abnormal result, uses different codes.
Why the bill can be much higher than the Medicare rate
Many plans cover screening mammograms without cost sharing, but a mammogram coded as diagnostic can leave you with a bill.
The Medicare rate is the global amount for the exam and the reading.
| If a line is billed at | It would be |
|---|---|
| 5x the Medicare rate | $631.30 |
| 10x the Medicare rate | $1,262.60 |
| 20x the Medicare rate | $2,525.20 |
The Medicare rate is a published benchmark, not a legal ceiling on what a provider may charge. Our free scan flags a line as worth a closer look when it is billed at more than 10 times the Medicare rate.
Questions worth asking before you pay
- Was my mammogram coded as screening or as diagnostic, and why?
- Was 3D tomosynthesis billed, and was it part of what I agreed to?
- Is the radiologist's reading billed separately?
