R92.34

Mammographic extreme density of breast

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R92.34 is a billable code used to indicate a diagnosis of mammographic extreme density of breast.

Key Diagnostic Point:

Mammographic extreme density of the breast refers to a condition where breast tissue appears denser than normal on a mammogram. This increased density can obscure the visibility of tumors or other abnormalities, making it more challenging to detect breast cancer. Extreme density is typically classified as having more than 75% of the breast tissue appearing dense on imaging. Women with dense breast tissue may have a higher risk of breast cancer, and this condition is often identified during routine screening mammograms. It is essential for healthcare providers to communicate the implications of dense breast tissue to patients, including the potential need for additional imaging studies, such as ultrasound or MRI, to ensure comprehensive evaluation. The clinical significance of extreme breast density necessitates careful monitoring and may influence screening recommendations.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in breast density classification among radiologists
  • Need for additional imaging studies based on density
  • Potential implications for breast cancer risk assessment
  • Documentation of patient communication regarding findings

Audit Risk Factors

  • Inadequate documentation of breast density findings
  • Failure to note additional imaging recommendations
  • Misclassification of breast density levels
  • Lack of patient education documentation

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include the patient's breast density classification, any recommendations for follow-up imaging, and discussions about breast cancer risk.

Common Clinical Scenarios

Routine screening mammograms revealing extreme breast density, follow-up consultations regarding imaging results.

Billing Considerations

Internal medicine providers should ensure that patients understand the implications of their mammogram results and the importance of follow-up.

Emergency Medicine

Documentation Requirements

Documentation must include the reason for the emergency visit, findings from imaging, and any immediate follow-up actions taken.

Common Clinical Scenarios

Patients presenting with breast pain or lumps who have a history of dense breast tissue.

Billing Considerations

Emergency providers should be aware of the need for timely follow-up imaging and referrals to specialists.

Frequently Asked Questions

What does extreme breast density mean?

Extreme breast density indicates that a significant portion of breast tissue appears dense on a mammogram, which can obscure the detection of tumors and may increase breast cancer risk.

How is extreme breast density assessed?

Extreme breast density is assessed through mammographic imaging, where radiologists classify breast density based on the proportion of dense versus fatty tissue.
