Code Description

ICD-10 N83.2 is a billable code used to indicate a diagnosis of other and unspecified ovarian cysts.

Key Diagnostic Point:

Ovarian cysts are fluid-filled sacs that develop on the ovaries. They can vary in size and may be functional or pathological. Functional cysts, such as follicular and corpus luteum cysts, are common and often resolve spontaneously. However, other types of cysts, including dermoid cysts, endometriomas, and cystadenomas, may require further evaluation and management. The presence of ovarian cysts can be associated with various conditions, including endometriosis, where endometrial tissue grows outside the uterus, leading to the formation of endometriomas. Additionally, ovarian cysts can be linked to hormonal imbalances, polycystic ovary syndrome (PCOS), and may contribute to symptoms such as pelvic pain, irregular menstrual cycles, and infertility. In some cases, cysts may rupture, leading to acute abdominal pain and necessitating surgical intervention. Accurate diagnosis often involves imaging studies such as ultrasound or MRI, and management may range from observation to surgical removal, depending on the cyst's characteristics and associated symptoms.

Specialty Considerations

Gynecologists should ensure proper coding based on the type of cyst and associated symptoms.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of ovarian cysts, improving the ability to capture the complexity of these conditions. N83.2 provides a catch-all for unspecified cysts, but coders must ensure accurate documentation to avoid misclassification.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of ovarian cysts, improving the ability to capture the complexity of these conditions. N83.2 provides a catch-all for unspecified cysts, but coders must ensure accurate documentation to avoid misclassification.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of ovarian cysts, improving the ability to capture the complexity of these conditions. N83.2 provides a catch-all for unspecified cysts, but coders must ensure accurate documentation to avoid misclassification.
