Code Description

ICD-10 N92 is a billable code used to indicate a diagnosis of excessive, frequent and irregular menstruation.

Key Diagnostic Point:

Excessive, frequent, and irregular menstruation encompasses a range of menstrual disorders characterized by abnormal uterine bleeding patterns. This condition can manifest as menorrhagia (heavy menstrual bleeding), polymenorrhea (frequent menstrual cycles), or oligomenorrhea (infrequent menstrual cycles). The underlying causes may include hormonal imbalances, uterine fibroids, polyps, endometriosis, or systemic conditions such as thyroid disorders. Patients may experience significant physical and emotional distress due to the unpredictability and severity of their menstrual cycles. Accurate diagnosis often requires a thorough medical history, physical examination, and possibly imaging studies or laboratory tests to identify the underlying etiology. Treatment options vary widely and may include hormonal therapies, surgical interventions, or lifestyle modifications, depending on the severity and cause of the symptoms. Understanding the nuances of this condition is crucial for effective management and coding.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes requiring differential diagnosis
  • Potential overlap with other menstrual disorders
  • Need for comprehensive documentation to support the diagnosis
  • Variability in treatment approaches based on individual patient factors

Audit Risk Factors

  • Inadequate documentation of symptoms and duration
  • Failure to specify the type of menstrual irregularity
  • Lack of supporting diagnostic tests or imaging
  • Misalignment between diagnosis and treatment provided

Inclusion Criteria

Use N92 When
  • According to ICD
  • 10 guidelines, N92 should be used when the menstrual irregularity is not due to pregnancy or other specified conditions
  • Coders should ensure that the documentation supports the diagnosis and that any related conditions are also coded appropriately

Exclusion Criteria

Do NOT use N92 When
No specific exclusions found.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of menstrual disorders, improving the ability to capture the complexity of conditions like N92. This specificity aids in better patient management and resource allocation.

ICD-9 vs ICD-10
