ICD code C49.9 is malignant cancer found in connective and soft tissue, but the exact location within the body is not specified.

1. Presence of a malignant (cancerous) tumor identified in connective or soft tissue

2. Tumor location cannot be further specified to a particular anatomical site within the connective or soft tissue

3. Histopathological confirmation of malignancy in tissue sample

4. Clinical presentation may include a painless or painful mass, swelling, or lump in soft tissue

5. Imaging studies (such as MRI, CT, or ultrasound) indicate a soft tissue mass with features suggestive of malignancy

6. No evidence that the tumor originated from bone, skin, or other specific organ systems

7. Absence of sufficient information to classify the tumor under a more specific connective or soft tissue neoplasm code
