Code Description

ICD-10 N83.01 is a billable code used to indicate a diagnosis of follicular cyst of right ovary.

Key Diagnostic Point:

A follicular cyst of the right ovary is a fluid-filled sac that develops on the ovary as a result of the normal menstrual cycle. These cysts occur when the follicle, which is supposed to release an egg, fails to do so and continues to grow. Follicular cysts are typically benign and often asymptomatic, but they can cause discomfort or pain if they become large or rupture. In some cases, they may lead to complications such as ovarian torsion or hemorrhage. Diagnosis is usually made through pelvic ultrasound, which can help differentiate between a follicular cyst and other ovarian masses, such as endometriomas or neoplasms. Management often involves monitoring the cyst, as many resolve spontaneously within a few menstrual cycles. However, persistent or symptomatic cysts may require surgical intervention. Understanding the nature of follicular cysts is crucial for differentiating them from other ovarian disorders, including endometriosis, which involves the presence of endometrial tissue outside the uterus, and ovarian neoplasms, which may require more aggressive treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other ovarian cysts and masses
  • Potential for complications such as rupture or torsion
  • Variability in clinical presentation and symptoms
  • Need for imaging studies to confirm diagnosis

Audit Risk Factors

  • Inadequate documentation of symptoms or clinical findings
  • Failure to specify the laterality of the cyst
  • Misclassification of cyst type (e.g., confusing with endometriomas)
  • Lack of follow-up documentation for monitoring

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed documentation of symptoms, imaging results, and treatment plans is essential.

Common Clinical Scenarios

Management of asymptomatic cysts, evaluation of pain related to cysts, and surgical intervention for large or symptomatic cysts.

Billing Considerations

Coders should be aware of the need for clear documentation of the cyst's characteristics and any associated complications.

Radiology

Documentation Requirements

Radiology reports must clearly describe the findings of imaging studies, including size and characteristics of the cyst.

Common Clinical Scenarios

Ultrasound evaluation of pelvic pain, follow-up imaging for known cysts, and differentiation from other pelvic masses.

Billing Considerations

Accurate coding relies on the specificity of imaging findings and their correlation with clinical symptoms.

Coding Guidelines

  • 01 should be used when a follicular cyst is specifically identified on the right ovary
  • Coders must ensure that the diagnosis is supported by clinical documentation and imaging results

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, including follicular cysts. This specificity aids in better tracking of ovarian disorders and improves the quality of care through targeted management strategies.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of ovarian conditions, including follicular cysts. This specificity aids in better tracking of ovarian disorders and improves the quality of care through targeted management strategies.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of ovarian conditions, including follicular cysts. This specificity aids in better tracking of ovarian disorders and improves the quality of care through targeted management strategies.

Frequently Asked Questions

What is the difference between a follicular cyst and an endometrioma?

A follicular cyst is a fluid-filled sac that forms during the menstrual cycle, while an endometrioma is a cyst formed from endometrial tissue that can develop in women with endometriosis. Endometriomas are often associated with chronic pelvic pain and require different management.
