Code Description

ICD-10 N94.5 is a billable code used to indicate a diagnosis of secondary dysmenorrhea.

Key Diagnostic Point:

Secondary dysmenorrhea refers to menstrual pain that is caused by an underlying reproductive health condition, rather than being a primary condition itself. This type of dysmenorrhea is often associated with conditions such as endometriosis, pelvic inflammatory disease, fibroids, or adenomyosis. Unlike primary dysmenorrhea, which is typically linked to the menstrual cycle without any identifiable pathology, secondary dysmenorrhea is characterized by pain that may begin earlier in the menstrual cycle and can last longer. Patients may experience symptoms such as severe cramping, lower back pain, and discomfort during intercourse. Diagnosis often involves a thorough medical history, pelvic examination, and imaging studies such as ultrasound or MRI to identify any underlying conditions. Treatment options may include hormonal therapies, pain management strategies, or surgical interventions depending on the underlying cause. Accurate coding of secondary dysmenorrhea is crucial for appropriate management and reimbursement, as it reflects the complexity of the patient's condition and the need for targeted treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of underlying conditions causing dysmenorrhea.
  • Differentiation from primary dysmenorrhea can be challenging.
  • Documentation must specify the underlying cause for accurate coding.
  • Potential for multiple co-existing conditions complicating the diagnosis.

Audit Risk Factors

  • Inadequate documentation of underlying conditions.
  • Failure to link symptoms to specific diagnoses.
  • Misclassification between primary and secondary dysmenorrhea.
  • Lack of supporting imaging or clinical findings.

Frequently Asked Questions

What is the difference between primary and secondary dysmenorrhea?

Primary dysmenorrhea is menstrual pain not associated with any underlying reproductive health condition, while secondary dysmenorrhea is caused by identifiable conditions such as endometriosis or fibroids.
