Code Description

ICD-10 N73 is a billable code used to indicate a diagnosis of other female pelvic inflammatory diseases.

Key Diagnostic Point:

N73 encompasses a variety of conditions affecting the female reproductive organs, primarily characterized by inflammation. This includes salpingitis (inflammation of the fallopian tubes), oophoritis (inflammation of the ovaries), pelvic inflammatory disease (PID), endometritis (inflammation of the endometrium), and cervicitis (inflammation of the cervix). These conditions can arise from various infectious agents, including sexually transmitted infections (STIs) such as Chlamydia trachomatis and Neisseria gonorrhoeae, as well as non-STI pathogens. Symptoms may include pelvic pain, abnormal vaginal discharge, fever, and dyspareunia. Diagnosis typically involves a combination of clinical evaluation, laboratory tests, and imaging studies. Treatment often includes antibiotics to target the underlying infection, and in severe cases, surgical intervention may be necessary. Accurate coding is crucial for appropriate management and reimbursement, as these conditions can lead to significant complications, including infertility and chronic pelvic pain if left untreated.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes and symptoms
  • Overlap with other gynecological conditions
  • Need for precise documentation of clinical findings
  • Potential for co-morbidities that complicate coding

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to specify the type of pelvic inflammatory disease
  • Misclassification of the condition as a non-inflammatory disease
  • Inconsistent coding of related procedures

Frequently Asked Questions

What are the common causes of N73?

N73 can be caused by various infectious agents, including STIs like Chlamydia and Gonorrhea, as well as other bacteria that may ascend from the cervix to the upper reproductive tract.

How is N73 treated?

Treatment typically involves antibiotics to address the underlying infection. In severe cases, surgical intervention may be necessary to manage complications.
