Code Description

ICD-10 N83.00 is a billable code used to indicate a diagnosis of follicular cyst of ovary, unspecified side.

Key Diagnostic Point:

Follicular cysts are fluid-filled sacs that develop on the ovaries during the menstrual cycle. They are typically benign and often resolve spontaneously without treatment. These cysts form when the follicle, which normally releases an egg during ovulation, fails to rupture and release the egg, leading to fluid accumulation. While most women experience follicular cysts at some point, they can sometimes cause symptoms such as pelvic pain, irregular menstrual cycles, or pressure symptoms if they grow large. In some cases, they may be associated with conditions like endometriosis or polycystic ovary syndrome (PCOS). Diagnosis is usually made through pelvic ultrasound, which can help differentiate between a simple cyst and other ovarian disorders. Management may include observation, hormonal therapy, or surgical intervention if complications arise. Understanding the implications of follicular cysts is crucial, especially in the context of other gynecological conditions such as endometriosis, which can complicate the clinical picture.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other types of ovarian cysts (e.g., dermoid cysts, endometriomas)
  • Potential overlap with other gynecological conditions (e.g., endometriosis, PCOS)
  • Need for imaging studies to confirm diagnosis
  • Variability in clinical presentation and symptomatology

Audit Risk Factors

  • Inadequate documentation of cyst characteristics
  • Failure to specify laterality when applicable
  • Misdiagnosis of cyst type leading to incorrect coding
  • Lack of follow-up documentation for resolved cysts

Frequently Asked Questions

What is the difference between a follicular cyst and a dermoid cyst?

Follicular cysts are fluid-filled sacs that develop during the menstrual cycle, while dermoid cysts are a type of teratoma that can contain various types of tissue, such as hair, skin, and teeth. Dermoid cysts are typically more complex and may require surgical intervention.
