Code Description

ICD-10 N83.02 is a billable code used to indicate a diagnosis of follicular cyst of left ovary.

Key Diagnostic Point:

A follicular cyst of the left ovary is a fluid-filled sac that develops on the ovary during the menstrual cycle. These cysts are typically benign and arise from the ovarian follicles that fail to rupture and release an egg. Follicular cysts can vary in size and may cause symptoms such as pelvic pain, irregular menstrual cycles, or pressure symptoms. In some cases, they may resolve spontaneously without treatment. However, larger cysts can lead to complications such as rupture, which may cause acute abdominal pain and require surgical intervention. The presence of a follicular cyst can also complicate the diagnosis of other ovarian disorders, such as endometriosis or polycystic ovary syndrome (PCOS), making accurate coding essential for proper management and treatment. Clinicians must differentiate between benign cysts and more serious conditions, including ovarian tumors, to ensure appropriate care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other ovarian cyst types (e.g., corpus luteum cysts, dermoid cysts)
  • Potential for complications such as rupture or torsion
  • Need for imaging studies to confirm diagnosis
  • Variability in clinical presentation and symptoms

Audit Risk Factors

  • Inadequate documentation of cyst characteristics
  • Failure to document symptoms or complications
  • Misclassification of cyst type
  • Lack of imaging results in the medical record
