Personal history of malignant neoplasm of soft tissue

This code indicates that a patient has a past medical history of a malignant tumor originating in the body's soft tissues, such as muscle, fat, fibrous tissue, or blood vessels. The neoplasm is no longer present, either due to successful treatment or spontaneous remission, but its prior existence is clinically significant for ongoing care.

Use this code when documenting a patient's history of a soft tissue sarcoma or other malignant soft tissue tumor that has been definitively treated and is currently in remission or cured. This is relevant for follow-up care, surveillance for recurrence, or when the history impacts current treatment decisions for unrelated conditions.

• Do not use this code if the patient has an active soft tissue malignancy; instead, code the active neoplasm.
• Ensure documentation specifies the primary site of the soft tissue malignancy if known, as this code is for a general history.
• Distinguish carefully from a history of skin cancer (melanoma, squamous cell carcinoma, etc.), which is coded separately.
