ICD-10 Code for Screening Mammogram Order
The appropriate ICD-10 code for a screening mammogram order is Z12.31 (Encounter for screening mammogram for malignant neoplasm of breast). 1
Coding Guidelines for Screening Mammography
- Z12.31 is the specific ICD-10 code designated for screening mammography encounters when there are no symptoms, signs, or history of breast disease 1
- This code should be used when ordering routine screening mammograms for asymptomatic patients 1
- The code indicates that the purpose of the encounter is for preventive screening rather than diagnostic evaluation 1
Screening vs. Diagnostic Mammography Coding
- Screening mammography (Z12.31) is performed on asymptomatic patients with no breast complaints or abnormalities 1
- Diagnostic mammography requires different coding based on the specific indication (symptoms, follow-up of abnormality, etc.) 1
- If the patient has a personal history of breast cancer, use Z85.3 (Personal history of malignant neoplasm of breast) as a secondary code 1
Age-Based Screening Recommendations and Coding
- For women aged 40 and older, annual screening mammography is recommended by many organizations, and Z12.31 would be the appropriate code 1
- For high-risk women under 40 who qualify for screening, Z12.31 would still be the appropriate code, though additional risk factor codes may be beneficial 1
- For transgender patients meeting screening criteria, Z12.31 is still the appropriate code for breast cancer screening 1
Risk-Based Coding Considerations
- For patients with increased risk factors, consider adding appropriate secondary codes:
Common Coding Pitfalls to Avoid
- Do not use diagnostic codes (such as N60-N65 breast disorders) for screening examinations 1
- Avoid using general screening code Z12.39 (Encounter for other screening for malignant neoplasm of breast) when the more specific Z12.31 is appropriate 1
- Do not use Z01.89 (Encounter for other specified special examinations) for breast cancer screening as it is too general 1
Follow-Up Coding After Screening
- If a screening mammogram reveals an abnormality requiring additional imaging, the subsequent visit should be coded with the appropriate diagnostic code rather than Z12.31 1
- For short-interval follow-up of probably benign findings (BI-RADS 3), use the appropriate diagnostic code rather than the screening code 1
