Code Description

ICD-10 N73.4 is a billable code used to indicate a diagnosis of female chronic pelvic peritonitis.

Key Diagnostic Point:

Chronic pelvic peritonitis in females is a prolonged inflammatory condition affecting the peritoneum, the membrane lining the abdominal cavity. This condition often arises as a complication of pelvic inflammatory disease (PID), which can be caused by infections such as salpingitis (inflammation of the fallopian tubes), oophoritis (inflammation of the ovaries), endometritis (inflammation of the endometrium), or cervicitis (inflammation of the cervix). Chronic pelvic peritonitis may present with persistent pelvic pain, abnormal vaginal discharge, and discomfort during intercourse. Diagnosis typically involves a combination of clinical evaluation, imaging studies, and laboratory tests to identify underlying infections. Treatment often includes antibiotic therapy targeting the specific pathogens involved, and in some cases, surgical intervention may be necessary to address complications or remove affected tissues. The chronic nature of this condition can lead to significant morbidity, affecting a woman's quality of life and reproductive health.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and chronic conditions
  • Identifying underlying causes such as PID or other infections
  • Need for comprehensive documentation of symptoms and treatments
  • Potential for co-existing gynecological conditions

Audit Risk Factors

  • Inadequate documentation of chronicity
  • Failure to document underlying infections or conditions
  • Lack of clarity in treatment plans and responses
  • Misclassification of acute versus chronic conditions

Frequently Asked Questions

What are the common causes of chronic pelvic peritonitis?

Chronic pelvic peritonitis is often caused by recurrent pelvic inflammatory disease, which can result from infections such as salpingitis, oophoritis, endometritis, or cervicitis. Other factors may include previous surgeries or conditions that lead to chronic inflammation.
