Code Description

ICD-10 N73.1 is a billable code used to indicate a diagnosis of chronic parametritis and pelvic cellulitis.

Key Diagnostic Point:

Chronic parametritis and pelvic cellulitis are inflammatory conditions affecting the pelvic region, often resulting from untreated or inadequately treated pelvic inflammatory disease (PID). This condition is characterized by the inflammation of the parametrium, the connective tissue surrounding the uterus, and can lead to the formation of cellulitis in the pelvic area. Chronic parametritis may arise from recurrent infections, such as salpingitis (inflammation of the fallopian tubes), oophoritis (inflammation of the ovaries), or endometritis (inflammation of the endometrium). Symptoms may include chronic pelvic pain, abnormal vaginal discharge, and dyspareunia (painful intercourse). Diagnosis typically involves a combination of clinical evaluation, imaging studies, and laboratory tests to identify the underlying infectious agents. Treatment often includes a course of broad-spectrum antibiotics to address the infection, along with pain management strategies. In some cases, gynecological procedures such as laparoscopy may be necessary to assess and treat complications. Accurate coding is essential for proper reimbursement and to reflect the complexity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and chronic conditions
  • Identifying associated infections (e.g., PID, salpingitis)
  • Documenting the severity and duration of symptoms
  • Understanding the relationship between multiple gynecological conditions

Audit Risk Factors

  • Inadequate documentation of chronicity
  • Failure to link symptoms to the diagnosis
  • Misidentification of the primary diagnosis
  • Lack of clarity on treatment plans and outcomes

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed patient history, including previous infections, treatment responses, and symptom duration.

Common Clinical Scenarios

Patients presenting with chronic pelvic pain, recurrent infections, or complications from PID.

Billing Considerations

Ensure all related conditions are documented to support the complexity of the diagnosis.

Infectious Disease

Documentation Requirements

Comprehensive records of laboratory results, treatment regimens, and patient responses to antibiotics.

Common Clinical Scenarios

Patients with recurrent pelvic infections requiring specialized antibiotic therapy.

Billing Considerations

Documenting the specific pathogens involved and their resistance patterns can impact treatment and coding.

  • According to ICD
  • 10 guidelines, N73
  • 1 should be used when the condition is chronic and documented as such
  • It is important to ensure that the diagnosis is supported by clinical findings and that any associated conditions are also coded appropriately
