Code Description

ICD-10 C77.5 is a billable code used to indicate a diagnosis of secondary and unspecified malignant neoplasm of intrapelvic lymph nodes.

Key Diagnostic Point:

C77.5 refers to secondary malignant neoplasms that have metastasized to the intrapelvic lymph nodes. This condition typically arises from a primary cancer located elsewhere in the body, such as the breast, prostate, or gastrointestinal tract. The lymphatic system serves as a pathway for cancer cells to spread, leading to the involvement of lymph nodes in the pelvis. The diagnosis of C77.5 is often made through imaging studies, such as CT scans or MRIs, and confirmed via biopsy. Patients may present with symptoms related to the primary malignancy or may be asymptomatic. The staging of metastatic disease is crucial, as it influences treatment decisions and prognosis. Palliative care considerations are significant for patients with C77.5, focusing on symptom management and quality of life, especially in advanced stages where curative treatment is not feasible. Accurate coding requires thorough documentation of the primary site, staging, and any treatments administered.

  • Potential for multiple metastatic sites complicating coding
  • Documentation of palliative care measures

Audit Risk Factors

  • Inadequate documentation of the primary cancer site
  • Failure to document staging details
  • Misclassification of lymph node involvement
  • Lack of clarity in palliative care documentation

Coding Guidelines

Inclusion Criteria

Use C77.5 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the primary malignancy is documented and that C77
  • 5 is used only when there is confirmed metastatic involvement of the intrapelvic lymph nodes

Exclusion Criteria

Do NOT use C77.5 When
  • Exclude cases where the lymph node involvement is due to benign conditions

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of metastatic diseases, improving the accuracy of cancer registries and treatment planning. C77.5 provides a clear designation for intrapelvic lymph node involvement, which is crucial for patient management.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of metastatic diseases, improving the accuracy of cancer registries and treatment planning. C77.5 provides a clear designation for intrapelvic lymph node involvement, which is crucial for patient management.
