Code Description

ICD-10 N85.6 is a billable code used to indicate a diagnosis of intrauterine synechiae.

Key Diagnostic Point:

Intrauterine synechiae, also known as Asherman's syndrome, is a condition characterized by the formation of scar tissue within the uterine cavity. This condition often arises after trauma to the endometrium, such as from surgical procedures like dilation and curettage (D&C), cesarean sections, or infections. The presence of synechiae can lead to various reproductive issues, including infertility, recurrent pregnancy loss, and abnormal menstrual cycles. Clinically, patients may present with symptoms such as amenorrhea, dysmenorrhea, or infertility, although some may be asymptomatic. Diagnosis is typically confirmed through hysterosalpingography (HSG) or hysteroscopy, which allows for direct visualization of the uterine cavity. Treatment options may include hysteroscopic resection of the synechiae, which can restore normal uterine function and improve reproductive outcomes. Understanding the implications of intrauterine synechiae is crucial for managing patients with a history of uterine surgery or recurrent pregnancy loss.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of surgical history and its impact on uterine health.
  • Differentiation from other uterine disorders such as fibroids or polyps.
  • Documentation must specify the extent and impact of synechiae.
  • Potential for co-morbid conditions affecting reproductive health.

Audit Risk Factors

  • Inadequate documentation of surgical history.
  • Failure to specify the type and extent of synechiae.
  • Misclassification with other uterine disorders.
  • Lack of supporting diagnostic imaging reports.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of intrauterine conditions, improving the accuracy of diagnoses and treatment plans. N85.6 provides a clear classification for intrauterine synechiae, which was less defined in ICD-9.

ICD-9 vs ICD-10
