Code Description

ICD-10 N83.299 is a billable code used to indicate a diagnosis of other ovarian cyst, unspecified side.

Key Diagnostic Point:

N83.299 refers to other types of ovarian cysts that do not fall into the more commonly classified categories such as functional cysts or neoplasms. Ovarian cysts are fluid-filled sacs that develop on the ovaries and can vary in size and type. They may arise from various conditions, including endometriosis, where endometrial tissue grows outside the uterus, leading to the formation of endometriomas. These cysts can cause pelvic pain, irregular menstrual cycles, and complications such as rupture or torsion. In cases of female genital prolapse, cysts may also be associated with structural changes in the pelvic floor. Fistulas, while not directly related to ovarian cysts, can occur in the context of pelvic pathology and complicate the clinical picture. Other ovarian disorders, such as polycystic ovary syndrome (PCOS), may also present with multiple cysts, but N83.299 specifically captures those cysts that do not fit neatly into these categories. Accurate diagnosis and documentation are crucial for appropriate coding and management of these conditions.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of cyst types that can be classified under this code
  • Need for precise documentation to differentiate from other ovarian conditions
  • Potential overlap with endometriosis and other gynecological disorders
  • Variability in clinical presentation and symptoms

Audit Risk Factors

  • Insufficient documentation of cyst characteristics
  • Failure to specify the side of the cyst when applicable
  • Inaccurate coding due to overlapping symptoms with other conditions
  • Lack of clarity in the clinical notes regarding the diagnosis

Specialty Focus

Medical Specialties

Gynecology

Documentation Requirements

Detailed clinical notes describing the cyst's characteristics, symptoms, and any imaging studies performed.

Common Clinical Scenarios

Patients presenting with pelvic pain, abnormal bleeding, or findings on ultrasound.

Billing Considerations

Ensure that the documentation clearly differentiates between types of cysts and related conditions.

Radiology

Documentation Requirements

Clear imaging reports that specify the size, location, and characteristics of the cyst.

Common Clinical Scenarios

Ultrasound or MRI findings of ovarian cysts in patients with pelvic pain.

Billing Considerations

Radiologists should provide detailed descriptions to aid in accurate coding.

Gynecologists should ensure that the procedure is justified based on clinical 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 conditions, but N83.299 remains a catch-all for unspecified cysts, which can lead to potential coding inaccuracies if not documented properly.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of ovarian conditions, but N83.299 remains a catch-all for unspecified cysts, which can lead to potential coding inaccuracies if not documented properly.
