C77.5

Secondary and unspecified malignant neoplasm of intrapelvic lymph nodes

Clinical Classification Guidelines

Medical Intelligence & Overview

ICD-10 Code C77.5 refers to secondary and unspecified malignant neoplasms affecting the lymph nodes located within the pelvic region. This classification is used when cancer has spread to the intrapelvic lymph nodes from another primary site or when the origin of the cancer is unknown. These lymph nodes are part of the lymphatic system, which plays a vital role in fighting infections and maintaining fluid balance. When cancer cells invade these nodes, it often signifies an advanced stage of disease, requiring careful evaluation and management.

Causes & Symptoms

Clinical Causes: Metastasis from primary tumors located in organs such as the pelvic organs (bladder, rectum, cervix, prostate, or uterus). Spread from cancers outside the pelvic region that have metastasized via lymphatic pathways. Recurrent or progressive spread of lymphatic cancer without a clearly identified primary site (unspecified malignancy).

Key Symptoms: Swelling or palpable mass in the pelvic area Persistent pain or discomfort in the pelvis or lower abdomen Unexplained weight loss and fatigue Changes in bowel or bladder habits Feeling of fullness or pressure in the pelvic region Signs related to the primary tumor site, if known

Diagnostic & Treatment

Diagnosis Path: Imaging studies such as computed tomography (CT) scans, magnetic resonance imaging (MRI), or positron emission tomography (PET) scans to identify enlarged or abnormal lymph nodes. Biopsy procedures, including needle biopsy or surgical excision, to obtain tissue samples for histopathological examination. Laboratory tests to assess overall health and identify tumor markers, if applicable. Review of medical history and prior cancers to determine the most likely primary source.

Treatment Protocols: Systemic therapies such as chemotherapy, targeted therapy, or immunotherapy tailored to the primary cancer type or the metastatic disease. Radiation therapy to control local disease and reduce symptoms. Surgical intervention may be considered in select cases to remove affected lymph nodes or to manage complications. Supportive care to address symptoms and maintain quality of life, including pain management and palliative treatments.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
