Code Description

ICD-10 N73.9 is a billable code used to indicate a diagnosis of female pelvic inflammatory disease, unspecified.

Key Diagnostic Point:

Female pelvic inflammatory disease (PID) is an infection of the female reproductive organs, which can include the uterus (endometritis), fallopian tubes (salpingitis), and ovaries (oophoritis). PID is often caused by sexually transmitted infections (STIs) such as chlamydia and gonorrhea, but can also result from other infections. Symptoms may include pelvic pain, fever, abnormal vaginal discharge, and pain during intercourse. The condition can lead to serious complications, including infertility, ectopic pregnancy, and chronic pelvic pain if left untreated. Diagnosis typically involves a combination of clinical evaluation, laboratory tests, and imaging studies. Treatment usually consists of broad-spectrum antibiotics to cover the most common pathogens. In some cases, surgical intervention may be necessary to address abscesses or other complications. The unspecified nature of this code indicates that the specific type of PID has not been documented, which can complicate treatment and management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in symptoms and presentation of PID
  • Need for thorough documentation to specify the type of PID
  • Potential for co-existing conditions that may complicate coding
  • Differentiation from other gynecological conditions

Audit Risk Factors

  • Inadequate documentation of symptoms and treatment
  • Failure to specify the type of PID
  • Inconsistent coding practices among providers
  • Misalignment between diagnosis and treatment provided

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed clinical notes including symptoms, diagnostic tests, and treatment plans.

Common Clinical Scenarios

Patients presenting with pelvic pain, abnormal discharge, or fever.

Billing Considerations

Ensure documentation reflects the specific type of PID when possible to avoid unspecified coding.

Infectious Disease

Documentation Requirements

Comprehensive history of STIs, laboratory results, and treatment response.

Common Clinical Scenarios

Patients with recurrent PID or those requiring hospitalization for severe infections.

Billing Considerations

Documenting the causative organism can help in coding and treatment decisions.

  • According to ICD
  • 10 guidelines, N73
  • 9 is used when the specific type of PID is not documented
  • Coders should ensure that all relevant clinical information is captured to support the diagnosis

Exclusion Criteria

Do NOT use N73.9 When
  • Exclusion criteria include conditions that are not classified as PID

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of PID, which can improve treatment planning and reimbursement. However, the unspecified nature of N73.9 may lead to challenges in accurately capturing the severity and type of PID.

Frequently Asked Questions

What are the common causes of PID?

PID is commonly caused by sexually transmitted infections, particularly chlamydia and gonorrhea, but can also result from other bacterial infections.

How is PID diagnosed?

Diagnosis of PID typically involves a clinical evaluation, laboratory tests for STIs, and imaging studies to assess for complications.

What are the potential complications of untreated PID?

Untreated PID can lead to serious complications such as infertility, ectopic pregnancy, and chronic pelvic pain.
