R92.33

Mammographic heterogeneous density of breast

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

Code Description

ICD-10 R92.33 is a billable code used to indicate a diagnosis of mammographic heterogeneous density of breast.

Key Diagnostic Point:

Mammographic heterogeneous density of the breast refers to a specific finding on a mammogram where the breast tissue appears denser than normal. This density can obscure the visibility of tumors or other abnormalities, making it more challenging to detect breast cancer. Heterogeneous density is characterized by varying levels of density within the breast, which may be due to a combination of glandular and fibrous tissue. Women with dense breast tissue may have a higher risk of breast cancer, and this finding necessitates further evaluation and monitoring. It is essential for healthcare providers to communicate the implications of this finding to patients, as it may influence screening strategies and the need for additional imaging, such as ultrasound or MRI. The clinical significance of heterogeneous density lies in its potential to mask lesions, thus requiring careful interpretation of mammographic results and consideration of the patient's overall risk factors.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in breast tissue density among patients
  • Need for correlation with clinical findings and history
  • Potential for additional imaging studies
  • Influence on screening recommendations

Audit Risk Factors

  • Inadequate documentation of patient education regarding dense breast tissue
  • Failure to document follow-up imaging or recommendations
  • Misinterpretation of mammogram results leading to incorrect coding
  • Lack of correlation with clinical findings

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include a detailed description of the mammographic findings, any associated symptoms, and the patient's risk factors for breast cancer.

Common Clinical Scenarios

Routine screening mammograms revealing heterogeneous density, follow-up evaluations for patients with a family history of breast cancer.

Billing Considerations

Consideration of the patient's age, hormonal status, and any previous breast surgeries or biopsies.

Emergency Medicine

Documentation Requirements

Acute care documentation should include the reason for the mammogram, findings, and any immediate follow-up actions taken.

Common Clinical Scenarios

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

Billing Considerations

Rapid assessment of findings and coordination with radiology for immediate follow-up imaging if necessary.

Coding Guidelines

Inclusion Criteria

Use R92.33 When
  • According to the official ICD
  • CM guidelines, R92
  • 33 should be used when the mammogram specifically indicates heterogeneous density without any associated findings of malignancy
  • Coders should ensure that the documentation supports the use of this code and that it is not used inappropriately for other breast conditions

Exclusion Criteria

Do NOT use R92.33 When
No specific exclusions found.

Documentation Requirements

Documentation must include the reason for the diagnostic mammogram and findings.

Specialty Considerations

Radiology specialists should ensure that the findings are clearly documented to support the diagnosis.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of breast findings, including heterogeneous density. This specificity aids in better tracking of breast health and outcomes, as well as improving the quality of care provided to patients.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of breast findings, including heterogeneous density. This specificity aids in better tracking of breast health and outcomes, as well as improving the quality of care provided to patients.

Reimbursement & Billing Impact

Frequently Asked Questions

What does heterogeneous density mean on a mammogram?

Heterogeneous density on a mammogram indicates that the breast tissue has varying levels of density, which can make it more difficult to detect abnormalities such as tumors. It is important for patients with this finding to discuss their mammogram results with their healthcare provider.
