R92.321

Mammographic fibroglandular density, right breast

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

Code Description

ICD-10 R92.321 is a billable code used to indicate a diagnosis of mammographic fibroglandular density, right breast.

Key Diagnostic Point:

Mammographic fibroglandular density refers to the composition of breast tissue as seen on a mammogram, where dense fibroglandular tissue appears white on the imaging, potentially obscuring lesions. This finding is significant as it can affect the sensitivity of mammography in detecting breast cancer. Women with higher fibroglandular density may have a higher risk of breast cancer, making it crucial for clinicians to monitor these patients closely. The density is categorized into four levels, with R92.321 specifically indicating a high level of density in the right breast. This code is used when the mammogram report notes this finding, which may not be associated with any symptoms but is an important factor in breast cancer screening and risk assessment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in mammographic reporting standards
  • Need for correlation with clinical findings
  • Potential for misinterpretation of density levels
  • Documentation of patient history and risk factors

Audit Risk Factors

  • Inadequate documentation of mammography findings
  • Failure to link density findings with patient risk factors
  • Misclassification of density levels
  • Lack of follow-up documentation for patients with high density

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Documentation should include the patient's breast density assessment, any associated risk factors, and recommendations for follow-up imaging or screening.

Common Clinical Scenarios

Patients presenting for routine screening mammograms who are found to have high fibroglandular density.

Billing Considerations

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

Emergency Medicine

Documentation Requirements

Acute care documentation should detail any acute breast symptoms, imaging results, and follow-up plans.

Common Clinical Scenarios

Patients presenting with breast pain or lumps who have a history of high fibroglandular density.

Billing Considerations

Emergency settings may require expedited imaging and documentation of findings for immediate care.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of breast density, improving the ability to track and manage patient care related to breast cancer risk.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of breast density, improving the ability to track and manage patient care related to breast cancer risk.

Reimbursement & Billing Impact
