Code Description

ICD-10 N83.10 is a billable code used to indicate a diagnosis of corpus luteum cyst of ovary, unspecified side.

Key Diagnostic Point:

A corpus luteum cyst is a fluid-filled sac that forms on the ovary after an egg has been released during ovulation. These cysts are typically benign and can occur on either side of the ovary, although this code is used when the side is unspecified. The cyst is formed from the corpus luteum, which is the structure that remains after the follicle has released the egg. In most cases, corpus luteum cysts resolve on their own without treatment. However, they can sometimes cause symptoms such as pelvic pain, irregular menstrual cycles, or pressure symptoms if they grow large. In the context of ovarian disorders, it is important to differentiate these cysts from other types of ovarian masses, such as endometriomas or neoplastic cysts. The presence of a corpus luteum cyst can also be significant in the evaluation of conditions like endometriosis, where the hormonal environment may influence cyst formation. Accurate diagnosis and coding are essential for appropriate management and treatment planning.

Code Complexity Analysis

Complexity Rating: Low

Low Complexity

Complexity Factors

  • Unspecified side may lead to ambiguity in clinical documentation.
  • Differentiation from other ovarian cysts requires careful evaluation.
  • Potential overlap with other conditions like endometriosis or neoplasms.
  • Documentation must clearly indicate the nature of the cyst.

Audit Risk Factors

  • Inadequate documentation of the cyst's characteristics.
  • Failure to specify the side of the cyst when applicable.
  • Misclassification of the cyst type (benign vs. malignant).
  • Lack of follow-up documentation if the cyst is monitored.

Specialty Focus

Gynecology

Documentation Requirements

Detailed imaging reports and clinical notes describing the cyst's characteristics and any associated symptoms.

Common Clinical Scenarios

Management of ovarian cysts during routine gynecological exams, evaluation of pelvic pain, and monitoring of cysts during pregnancy.

Billing Considerations

Ensure that the documentation specifies whether the cyst is symptomatic or asymptomatic and any relevant hormonal treatments.

Reproductive Endocrinology

Documentation Requirements

Comprehensive hormonal assessments and imaging studies to evaluate the impact of cysts on fertility.

Common Clinical Scenarios

Assessment of ovarian function in patients with infertility issues and monitoring of cysts during assisted reproductive technology cycles.

Billing Considerations

Document the relationship between the cyst and hormonal treatments or fertility interventions.

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 accuracy of diagnoses and treatment plans. N83.10 provides a clear designation for corpus luteum cysts, facilitating better tracking of these conditions in clinical practice.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of ovarian cysts, improving the accuracy of diagnoses and treatment plans. N83.10 provides a clear designation for corpus luteum cysts, facilitating better tracking of these conditions in clinical practice.

Reimbursement & Billing Impact

Frequently Asked Questions

What is a corpus luteum cyst?

A corpus luteum cyst is a fluid-filled sac that forms on the ovary after ovulation. It is typically benign and resolves on its own.

How is a corpus luteum cyst diagnosed?

Diagnosis is usually made through pelvic ultrasound, which can visualize the cyst and assess its characteristics.

What symptoms are associated with corpus luteum cysts?

Symptoms may include pelvic pain, irregular menstrual cycles, or pressure symptoms, but many cysts are asymptomatic.

When should a corpus luteum cyst be treated?

Treatment may be necessary if the cyst is large, symptomatic, or if there are concerns about malignancy.
