Code Description

ICD-10 N83.20 is a billable code used to indicate a diagnosis of unspecified ovarian cysts.

Key Diagnostic Point:

Unspecified ovarian cysts refer to fluid-filled sacs that develop on the ovaries, which may vary in size and can be asymptomatic or symptomatic. These cysts are common in women of reproductive age and can arise from various physiological processes, including follicular development and corpus luteum formation. While many ovarian cysts resolve spontaneously without intervention, some may lead to complications such as pain, rupture, or torsion. The presence of ovarian cysts can be associated with other conditions such as endometriosis, where endometrial tissue grows outside the uterus, potentially leading to the formation of endometriomas. Additionally, ovarian cysts may coexist with pelvic organ prolapse, where pelvic organs descend due to weakened pelvic support structures. Fistulas may also occur in the context of severe pelvic pathology, complicating the clinical picture. Accurate diagnosis often requires imaging studies, such as ultrasound or MRI, to differentiate between benign cysts and more serious ovarian disorders, including tumors or polyps of the female genital tract. The management of ovarian cysts is tailored to the individual, considering factors such as size, symptoms, and associated conditions.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and symptoms
  • Differentiation from other ovarian disorders
  • Potential for associated conditions (e.g., endometriosis, prolapse)
  • Need for imaging studies for accurate diagnosis

Audit Risk Factors

  • Insufficient documentation of symptoms
  • Lack of imaging results in the medical record
  • Inconsistent terminology used in clinical notes
  • Failure to document associated conditions

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed clinical notes including symptoms, imaging results, and treatment plans.

Common Clinical Scenarios

Routine gynecological exams revealing cysts, management of symptomatic cysts, and follow-up on previously diagnosed cysts.

Billing Considerations

Ensure clear documentation of the cyst type and any associated conditions to support coding.

Radiology

Documentation Requirements

Comprehensive imaging reports detailing cyst characteristics and differential diagnoses.

Common Clinical Scenarios

Ultrasound evaluations of pelvic pain, follow-up imaging for known cysts.

Billing Considerations

Radiology reports should clearly indicate findings related to cysts and any recommendations for further management.

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 accuracy of diagnoses and treatment plans. However, the use of unspecified codes like N83.20 can lead to challenges in data analysis and reimbursement.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of ovarian conditions, improving the accuracy of diagnoses and treatment plans. However, the use of unspecified codes like N83.20 can lead to challenges in data analysis and reimbursement.

Frequently Asked Questions

When should I use N83.20 instead of a more specific code?

Use N83.20 when the specific type of ovarian cyst is not documented in the medical record. If the type is known, opt for the more specific code to ensure accurate representation of the patient's condition.
