D492 - A growth or tumor in bone, soft tissue, or skin where doctors haven't yet determined if it's cancerous or non-cancerous

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code refers to a neoplasm (abnormal growth of cells forming a tumor or mass) found in bone, soft tissue, or skin where the behavior is unspecified. This means doctors have identified a growth but haven't yet determined through testing whether it's benign (non-cancerous), malignant (cancerous), or has uncertain potential. The 'unspecified behavior' classification is often used when initial examination has found a growth, but further testing like biopsy or imaging is needed to determine its exact nature. This is a common temporary diagnosis while doctors gather more information to make a definitive determination about the growth's characteristics and appropriate treatment plan.

Additional Information

This is often a temporary diagnosis used while awaiting further test results. The actual treatment and prognosis will depend on what additional testing reveals about the growth's specific characteristics. Patients should follow up promptly for recommended additional testing.
