Code Description

ICD-10 N73.0 is a billable code used to indicate a diagnosis of acute parametritis and pelvic cellulitis.

Key Diagnostic Point:

Acute parametritis and pelvic cellulitis are inflammatory conditions affecting the pelvic region, often resulting from infections of the reproductive organs. This condition typically arises as a complication of pelvic inflammatory disease (PID), which may involve salpingitis (inflammation of the fallopian tubes), oophoritis (inflammation of the ovaries), endometritis (inflammation of the endometrium), or cervicitis (inflammation of the cervix). The acute nature of this condition indicates a sudden onset, often characterized by severe pelvic pain, fever, and abnormal vaginal discharge. Diagnosis is usually made through clinical evaluation, imaging studies, and laboratory tests. Treatment often involves the use of broad-spectrum antibiotics to combat the underlying infection, and in some cases, surgical intervention may be necessary to drain abscesses or remove infected tissue. Accurate coding is essential for proper reimbursement and to reflect the severity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and chronic conditions
  • Identifying the specific underlying cause of the infection
  • Documenting associated conditions such as PID or endometritis
  • Understanding the implications of antibiotic treatment and surgical interventions

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to specify the underlying cause of the infection
  • Misclassification of acute versus chronic conditions
  • Lack of supporting lab results or imaging studies
