Code Description

ICD-10 N83.201 is a billable code used to indicate a diagnosis of unspecified ovarian cyst, right side.

Key Diagnostic Point:

An unspecified ovarian cyst on the right side refers to a fluid-filled sac that develops on the right ovary. These cysts are common and often benign, arising from the normal functioning of the ovaries during the menstrual cycle. They can be classified into functional cysts, such as follicular and corpus luteum cysts, or non-functional cysts, which may include dermoid cysts or endometriomas. While many ovarian cysts resolve spontaneously without treatment, some may cause symptoms such as pelvic pain, pressure, or discomfort, particularly if they rupture or become large. In cases where the cyst is associated with endometriosis, it may indicate the presence of endometriomas, which are cysts formed from endometrial tissue. The diagnosis of an unspecified ovarian cyst typically involves imaging studies, such as ultrasound, to assess the size and characteristics of the cyst. Management may vary based on symptoms, size, and the patient's reproductive plans, ranging from observation to surgical intervention if complications arise.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in symptoms and presentation of ovarian cysts
  • Differentiation between functional and pathological cysts
  • Potential overlap with other gynecological conditions
  • Need for imaging studies to confirm diagnosis

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to specify the type of cyst
  • Lack of imaging reports to support diagnosis
  • Misclassification of cysts as malignant without proper evidence

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed patient history, physical examination findings, imaging results, and treatment plans.

Common Clinical Scenarios

Routine check-ups revealing incidental ovarian cysts, patients presenting with pelvic pain, or cysts found during imaging for other reasons.

Billing Considerations

Ensure that the type of cyst is documented, especially if there is a suspicion of malignancy or if the cyst is symptomatic.

Radiology

Documentation Requirements

Clear imaging reports detailing the size, appearance, and characteristics of the cyst.

Common Clinical Scenarios

Ultrasound or MRI performed for pelvic pain or routine screening showing ovarian cysts.

Billing Considerations

Radiologists should provide comprehensive descriptions to aid in accurate coding and management decisions.

Coding Guidelines

Inclusion Criteria

Use N83.201 When
  • According to ICD
  • 10 guidelines, N83
  • 201 should be used when the specific type of ovarian cyst is not documented
  • It is important to ensure that the right side is specified, as coding for left
  • sided or bilateral cysts would require different codes

Exclusion Criteria

Do NOT use N83.201 When
No specific exclusions found.

Ovarian cyst aspiration

Clinical Scenario

Used when a cyst is aspirated for diagnostic or therapeutic purposes.

Documentation Requirements

Document the indication for aspiration and findings during the procedure.

Specialty Considerations

Gynecologists should ensure that the procedure is justified based on the patient's symptoms and imaging findings.

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 track and manage these conditions. N83.201 provides a clear designation 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 track and manage these conditions. N83.201 provides a clear designation for unspecified cysts, but coders must ensure accurate documentation to avoid misclassification.
