ICD-10: C77.2

ICD-10 code C77.2 refers to "Secondary and unspecified malignant neoplasm of intra-abdominal lymph nodes." This classification is part of the broader category of malignant neoplasms, which are tumors that can invade surrounding tissues and spread to other parts of the body. Below is a detailed overview of this code, including its clinical description, implications, and relevant coding guidelines.

Clinical Description

Definition

The term "secondary malignant neoplasm" indicates that the cancer has metastasized from a primary site to the intra-abdominal lymph nodes. This means that the cancer originated in another part of the body and has spread to the lymphatic system within the abdominal cavity. The lymph nodes are critical components of the immune system, and their involvement often signifies a more advanced stage of cancer.

Common Primary Sites

Secondary malignant neoplasms in the intra-abdominal lymph nodes can arise from various primary cancers, including but not limited to:
- Gastrointestinal cancers: Such as colorectal cancer, stomach cancer, and pancreatic cancer.
- Genitourinary cancers: Including cancers of the bladder, prostate, and kidneys.
- Gynecological cancers: Such as ovarian and uterine cancers.
- Lymphoproliferative disorders: Such as lymphoma, which can directly affect lymph nodes.

Symptoms

Patients with secondary malignant neoplasms of the intra-abdominal lymph nodes may present with a variety of symptoms, including:
- Abdominal pain or discomfort
- Swelling or a palpable mass in the abdomen
