CPT 77067: Screening Mammography, Bilateral
CPT 77067 reports bilateral screening mammography (a 2-view study of each breast), including computer-aided detection (CAD) when performed. It is the preventive breast-cancer screening code for asymptomatic patients. In 2026 Medicare pays about $126.26 for the global service, split into a professional (modifier 26) and technical (modifier TC) component.

What is CPT 77067 used for?
CPT 77067 reports screening mammography, bilateral (2-view study of each breast), including computer-aided detection (CAD) when performed. It is the preventive breast-cancer screening study for an asymptomatic patient. Because CAD is bundled into the code descriptor, you no longer report a separate CAD add-on — it is included whether or not CAD software is used.
The defining feature of 77067 is that it is screening: there is no sign, symptom, or known abnormality driving the study. The moment the patient has a lump, pain, nipple discharge, or an abnormal prior finding, the exam becomes diagnostic and a different code applies.
How much does 77067 pay in 2026, and how does the 26/TC split work?
The 2026 national Medicare allowed amount for the global study is about $126.26. With a PC/TC indicator of 1, it divides into professional and technical components:
| Component | Modifier | Covers | Approx. 2026 |
|---|---|---|---|
| Professional | 26 | Radiologist interpretation and report | ~$40 |
| Technical | TC | Mammography unit, technologist, CAD, overhead | ~$86 |
| Global | (none) | Both, same entity | ~$126.26 |
As a Medicare Part B preventive service, the screening mammogram is paid at 100 percent — the beneficiary owes no deductible or coinsurance. Confirm your locality amount with the Medicare fee calculator.
Screening versus diagnostic — the coding decision
Example: a 62-year-old woman with no breast symptoms comes in for her annual mammogram. This is 77067. A hospital would bill the technical resources through OPPS and the radiologist would bill 77067-26 for about $40. If, on that same visit, the radiologist finds a suspicious mass and orders additional workup views, the exam converts to diagnostic (77065/77066).
- Screening = asymptomatic patient, no known abnormality → 77067.
- Diagnostic = sign, symptom, or abnormal finding → 77065 (unilateral) or 77066 (bilateral).
- When a screening converts to diagnostic same day, follow payer rules and modifier GG for the same-day workup.
How does 77067 fit the mammography family?
Mammography codes split into screening and diagnostic, with CAD bundled into each.
- 77067 — screening mammography, bilateral (incl. CAD).
- 77065 — diagnostic mammography, unilateral (incl. CAD).
- 77066 — diagnostic mammography, bilateral (incl. CAD).
The professional and technical split applies to all three — see modifier 26 and modifier TC. Coverage for screening frequency is governed by Medicare Part B preventive rules.
Frequently asked questions
The 2026 national Medicare allowed amount for the global bilateral screening mammogram is about $126.26. As a covered preventive service under Part B, the screening mammogram is paid at 100 percent with no deductible or coinsurance for the beneficiary — a distinction from most radiology, where the patient owes 20 percent.
Append modifier 26 when a radiologist interprets a screening mammogram acquired elsewhere — the professional component. Append modifier TC when your imaging center owns the mammography unit and acquires the images but an outside physician reads them. Bill 77067 global only when the same facility both acquires and interprets the study.
77067 is bilateral SCREENING mammography for an asymptomatic patient. 77065 (unilateral) and 77066 (bilateral) are DIAGNOSTIC mammography, used when there is a sign, symptom, or abnormal finding that requires additional views and workup. All three include CAD when performed. Screening and diagnostic are chosen by the clinical indication, not by which breasts are imaged.
