Name: Bilateral Mammogram
Medical Specialty: Obstetrics / Gynecology
Description: Bilateral Mammogram (abnormal), additional views requested
(Medical Transcription Sample Report)
EXAM: Mammographic screening FFDM
HISTORY: 40-year-old female who is on oral contraceptive pills. She has no present symptomatic complaints. No prior history of breast surgery nor family history of breast CA.
TECHNIQUE: Standard CC and MLO views of the breasts.
COMPARISON: This is the patient’s baseline study.
FINDINGS: The breasts are composed of moderately to significantly dense fibroglandular tissue. The overlying skin is unremarkable.
There is a tiny cluster of calcifications in the right breast, near the central position associated with 11:30 on a clock.
There are benign-appearing calcifications in both breasts as well as unremarkable axillary lymph nodes.
There are no spiculated masses or architectural distortions.
IMPRESSION: Tiny cluster of calcifications at the 11:30 position of the right breast. Recommend additional views; spot magnification in the MLO and CC views of the right breast.
BIRADS Classification 0 – Incomplete
MAMMOGRAPHY INFORMATION:
1. A certain percentage of cancers, probably 10% to 15%, will not be identified by mammography.
2. Lack of radiographic evidence of malignancy should not delay a biopsy if a clinically suspicious mass is present.
3. These images were obtained with FDA-approved digital mammography equipment, and iCAD Second Look Software Version 7.2 was utilized.

CPT / HCPCS PROCEDURE CODES
Code for THIS Encounter
77067 – Screening mammography, bilateral (2-view study of each breast), including CAD
Rationale:
-
Exam is explicitly documented as screening mammography (FFDM)
-
Patient is asymptomatic
-
No prior breast cancer, surgery, or family history
-
Bilateral CC and MLO views performed
-
CAD software (iCAD Second Look) was used → included in code
-
BI-RADS 0 does not change the screening CPT code for this visit
Codes NOT Assigned for This Encounter
-
77065 / 77066 (Diagnostic mammography)
Not coded yet — additional views were recommended but not performed -
Add-on spot magnification codes
Not separately reportable; bundled into diagnostic mammography when performed
ICD-10-CM DIAGNOSIS CODES
Primary Diagnosis (Screening Visit)
Z12.31 – Encounter for screening mammogram for malignant neoplasm of breast
Rationale:
-
Patient presents without symptoms
-
Exam purpose was screening
-
Findings discovered during screening do not replace the screening diagnosis for this visit
Diagnosis Codes NOT Used Yet
-
R92.1 (Mammographic microcalcification)
Not reported until diagnostic imaging is performed -
N63 (Breast lump)
No palpable mass -
Z80.3 (Family history of breast cancer)
Explicitly denied in documentation
BI-RADS 0 Coding Guidance (Important)
BI-RADS 0 = Incomplete
-
Indicates need for additional imaging
-
Does NOT convert the screening mammogram into a diagnostic exam
-
Screening CPT remains valid for this encounter
Coding for the FOLLOW-UP Visit (When Additional Views Are Performed)
These codes are NOT billed today, but are included for coder clarity.
CPT
77065 – Diagnostic mammography, unilateral (right breast), including CAD
Rationale:
-
Additional spot magnification CC and MLO views
-
Imaging limited to right breast
-
CAD included
ICD-10-CM
R92.1 – Mammographic microcalcification
Rationale:
-
Used once imaging is diagnostic
-
Reflects the calcifications identified on screening
Final Coding Summary
| Category | Code | Description |
|---|---|---|
| CPT | 77067 | Screening bilateral mammogram w/CAD |
| ICD-10-CM | Z12.31 | Screening mammogram encounter |
| BI-RADS | 0 | Incomplete – additional imaging needed |
Key Coding Takeaways
-
Screening stays screening, even with abnormal findings
-
BI-RADS 0 ≠ diagnostic exam
-
Do not assign abnormal findings diagnosis codes until diagnostic imaging occurs
-
CAD is included, not separately billable
