R92.333

Mammographic heterogeneous density, bilateral breasts

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

Code Description

ICD-10 R92.333 is a billable code used to indicate a diagnosis of mammographic heterogeneous density, bilateral breasts.

Key Diagnostic Point:

Mammographic heterogeneous density refers to the presence of varying densities in breast tissue as seen on a mammogram. This finding indicates that the breast tissue is not uniformly dense, which can complicate the interpretation of mammograms and may obscure the detection of breast lesions. Heterogeneous density is characterized by a mix of fatty and glandular tissues, which can be influenced by factors such as age, hormonal changes, and genetic predisposition. Bilateral involvement suggests that both breasts exhibit this density pattern. Clinically, this finding may not present with specific symptoms; however, it can be associated with an increased risk of breast cancer, necessitating further evaluation. Patients may be advised to undergo additional imaging studies or biopsies based on the overall assessment of their breast health and risk factors. It is crucial for healthcare providers to document the findings accurately to ensure appropriate follow-up and management.

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

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

Common Clinical Scenarios

Routine screening mammograms revealing heterogeneous density in asymptomatic patients.

Billing Considerations

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

Emergency Medicine

Documentation Requirements

Acute care documentation should include the reason for imaging, findings, and any immediate interventions or referrals.

Common Clinical Scenarios

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

Billing Considerations

Emergency settings may require expedited follow-up and clear documentation of findings for continuity of care.
