R92.313

Mammographic fatty tissue density, bilateral breasts

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

Code Description

ICD-10 R92.313 is a billable code used to indicate a diagnosis of mammographic fatty tissue density, bilateral breasts.

Key Diagnostic Point:

Mammographic fatty tissue density refers to the composition of breast tissue as seen on a mammogram, where the density of fatty tissue is assessed. Bilateral breasts indicate that this finding is present in both breasts. Fatty tissue density is an important factor in mammography as it can influence the visibility of lesions or abnormalities. Higher density breast tissue can obscure tumors, making it more challenging to detect breast cancer. This finding is often reported in the context of routine screening mammograms and may lead to further imaging or follow-up if there are additional concerns. It is essential for healthcare providers to document the density findings accurately, as it can impact patient management and screening recommendations. The presence of fatty tissue density is generally considered a normal finding, but it is crucial to correlate it with other clinical findings and patient history to ensure comprehensive care.

Internal Medicine

Documentation Requirements

Documentation should include patient history, risk factors for breast cancer, and any previous imaging results.

Common Clinical Scenarios

Routine screening mammograms, follow-up on previous findings, and patient counseling regarding breast health.

Billing Considerations

Consideration of family history and genetic predisposition to breast cancer is essential for accurate coding.

Emergency Medicine

Documentation Requirements

Acute care documentation should include the reason for the mammogram, any presenting symptoms, and immediate findings.

Common Clinical Scenarios

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

Billing Considerations

Emergency settings may require expedited documentation and follow-up protocols.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of breast findings, including the differentiation between fatty tissue density and other types of breast density. This specificity aids in better patient management and research.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of breast findings, including the differentiation between fatty tissue density and other types of breast density. This specificity aids in better patient management and research.
