Question

in the neoplasm table, if the documentation states that the neoplasm has metastasized to an additional body site, this would be classified as

multiple choice

malignant primary.
malignant secondary.
uncertain behavior.
carcinoma in situ.

Explanation:

Analyze the clinical scenario

Using the Neoplasm Coding and ICD-10 Neoplasm Table knowledge points

The question asks how to classify a neoplasm that has "metastasized to an additional body site" using the ICD-10-CM Neoplasm Table.

Define the classification categories

Using the Primary Neoplasm and ICD-10 Neoplasm Table knowledge points

In medical coding, neoplasms are classified based on their behavior:

• Malignant Primary: The original, originating site of the cancer.
• Malignant Secondary: The site to which a primary cancer has spread or metastasized.
• Carcinoma in situ: A localized, non-invasive malignant neoplasm.
• Uncertain behavior: Neoplasms whose ultimate behavior cannot be determined at the time of biopsy.

Since the documentation states the neoplasm has metastasized to an additional site, this secondary site is classified as a malignant secondary neoplasm.

Answer:

• malignant primary.
• malignant secondary. (Correct answer)
• uncertain behavior.
• carcinoma in situ.
