Code Description

ICD-10 C54.8 is a billable code used to indicate a diagnosis of malignant neoplasm of overlapping sites of corpus uteri.

Key Diagnostic Point:

C54.8 refers to malignant neoplasms that occur in overlapping sites of the corpus uteri, which includes the body of the uterus. This code encompasses various types of uterine cancers that do not fit neatly into other specific categories. The corpus uteri is a common site for gynecologic malignancies, including endometrial carcinoma, which is the most prevalent type of uterine cancer. The diagnosis often involves a combination of imaging studies, histopathological examination, and tumor marker assessments, such as CA-125, which can aid in monitoring treatment response and disease progression. Staging of the malignancy is crucial for determining the appropriate treatment approach, which may include surgical intervention, radiation therapy, or chemotherapy. Surgical options often involve hysterectomy, which may be total or subtotal, depending on the extent of the disease. Accurate coding for C54.8 requires a thorough understanding of the clinical context and the specific characteristics of the neoplasm, as well as the documentation of any overlapping sites involved.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in tumor types and histology within overlapping sites
  • Need for precise documentation of tumor location and extent
  • Differentiation from other gynecologic malignancies
  • Staging complexity and its impact on treatment decisions

Audit Risk Factors

  • Inadequate documentation of tumor characteristics
  • Failure to document staging information
  • Misclassification of overlapping sites
  • Inconsistent use of CA-125 levels in documentation

Frequently Asked Questions

What is the significance of CA-125 in relation to C54.8?

CA-125 is a tumor marker that can be elevated in patients with malignant neoplasms of the uterus, including those coded as C54.8. It is often used to monitor treatment response and detect recurrence.
