R92.331

Mammographic heterogeneous density, right breast

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

Code Description

ICD-10 R92.331 is a billable code used to indicate a diagnosis of mammographic heterogeneous density, right breast.

Key Diagnostic Point:

Mammographic heterogeneous density refers to the presence of varying densities in breast tissue as observed on a mammogram. This finding indicates that the breast contains both dense and fatty tissues, which can complicate the interpretation of mammograms. Heterogeneous density is significant because it may obscure the visibility of lesions or abnormalities, potentially leading to missed diagnoses of breast cancer. The right breast is specified in this code, indicating that the findings are localized. Common symptoms associated with this finding may include palpable masses or changes in breast shape or size, although many patients may be asymptomatic. The clinical significance of heterogeneous density lies in its association with an increased risk of breast cancer, necessitating further evaluation through additional imaging or biopsy. Regular screening and follow-up are crucial for women with this finding to ensure early detection of any potential malignancies.

Audit Risk Factors

  • Inadequate documentation of imaging findings
  • Failure to link symptoms to the diagnosis
  • Misinterpretation of mammographic results
  • Lack of follow-up documentation

Specialty Focus

Documentation Requirements

Documentation should include a thorough history of breast health, any symptoms reported by the patient, and results from previous mammograms.

Common Clinical Scenarios

Patients presenting for routine screening or follow-up after previous abnormal findings.

Billing Considerations

Consideration of family history of breast cancer and other risk factors is essential for accurate coding.

Emergency Medicine

Documentation Requirements

Acute care documentation should include any presenting symptoms, imaging results, and immediate management plans.

Common Clinical Scenarios

Patients presenting with breast pain or palpable masses requiring urgent evaluation.

Billing Considerations

Emergency settings may require expedited imaging and documentation of findings for timely intervention.

Frequently Asked Questions

What does heterogeneous density mean in a mammogram?

Heterogeneous density indicates that there are areas of varying density in the breast tissue, which can make it more challenging to detect abnormalities.
