Code Description

ICD-10 N83.202 is a billable code used to indicate a diagnosis of unspecified ovarian cyst, left side.

Key Diagnostic Point:

An unspecified ovarian cyst on the left side refers to a fluid-filled sac that develops on the left ovary. These cysts can arise from various ovarian disorders, including functional cysts, which are common and typically resolve on their own, or pathological cysts, which may require further evaluation. The presence of an ovarian cyst can be associated with conditions such as endometriosis, where endometrial tissue grows outside the uterus, potentially leading to the formation of endometriomas. Additionally, ovarian cysts can be linked to female genital prolapse, where pelvic organs descend due to weakened pelvic support structures. In some cases, cysts may also be associated with fistulas, which are abnormal connections between organs. The diagnosis of an ovarian cyst is often made through imaging studies, such as ultrasound, and may require monitoring or intervention depending on the size, symptoms, and underlying conditions. Accurate coding is essential for proper management and treatment planning.

  • Differentiation from other ovarian disorders
  • Potential association with other gynecological conditions
  • Need for precise documentation of symptoms and imaging findings

Audit Risk Factors

  • Inadequate documentation of cyst characteristics
  • Failure to specify associated symptoms or conditions
  • Misclassification of cyst type
  • Lack of follow-up documentation for monitoring

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of ovarian conditions, improving the granularity of data for research and treatment outcomes. N83.202 provides a clear designation for unspecified cysts, facilitating better tracking and management of ovarian health.

ICD-9 vs ICD-10

Frequently Asked Questions

What is the difference between a functional and a pathological ovarian cyst?

Functional cysts are related to the normal functioning of the ovaries and typically resolve on their own, while pathological cysts may arise from underlying conditions and may require further evaluation or treatment.
