Question

when coding from the neoplasm table, the term primary refers to the condition as

multiple choice

the metastasized diagnosis.

the main diagnosis.

a slow-growing, benign tumor.

a neoplasm that is considered non-invasive.

Explanation:

Define the term primary in neoplasm coding

In medical coding, specifically when using the ICD-10-CM Neoplasm Table, neoplasms are classified by anatomical site and behavior. The behavior columns include Malignant Primary, Malignant Secondary, Ca in situ, Benign, Uncertain, and Unspecified. The term "primary" refers to the original, initial site of the cancer where the tumor first began to grow. In clinical and coding terms, this is considered the main diagnosis or the originating site of the malignant neoplasm.

Analyze the given options

• the metastasized diagnosis: This refers to a "secondary" neoplasm, which is a site to which the cancer has spread from its original location.
• the main diagnosis: In the context of coding a malignant neoplasm, the primary site represents the main, originating diagnosis of the cancer.
• a slow-growing, benign tumor: This describes a benign neoplasm, not a malignant primary neoplasm.
• a neoplasm that is considered non-invasive: This typically refers to carcinoma in situ (Ca in situ), where malignant cells are localized and have not invaded surrounding tissues.

Select the correct option

Based on the standard definitions in the ICD-10-CM coding guidelines, the term "primary" refers to the originating site of the cancer, which represents the main diagnosis of the neoplastic condition.

Answer:

• the metastasized diagnosis.
• the main diagnosis. (Correct answer)
• a slow-growing, benign tumor.
• a neoplasm that is considered non-invasive.
