Code Description

ICD-10 N83.1 is a billable code used to indicate a diagnosis of corpus luteum cyst.

Key Diagnostic Point:

A corpus luteum cyst is a functional ovarian cyst that forms after the ovary releases an egg during ovulation. Typically, the corpus luteum produces hormones, primarily progesterone, which are crucial for maintaining the early stages of pregnancy. If pregnancy does not occur, the corpus luteum usually degenerates. However, in some cases, it can fill with fluid and form a cyst. These cysts are generally benign and often resolve spontaneously without treatment. Symptoms may include pelvic pain, irregular menstrual cycles, or, in some cases, no symptoms at all. The presence of a corpus luteum cyst can be confused with other ovarian disorders, such as endometriosis or ovarian tumors, necessitating careful evaluation through imaging studies like ultrasound. In the context of endometriosis, the differentiation between a corpus luteum cyst and endometriotic cysts (chocolate cysts) is critical, as management strategies differ significantly. Additionally, the presence of a corpus luteum cyst may complicate the clinical picture in patients with female genital prolapse or fistulas, where pelvic anatomy is altered. Accurate diagnosis and coding are essential for appropriate management and treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other ovarian cysts and disorders
  • Potential overlap with endometriosis and other pelvic conditions
  • Variability in clinical presentation and symptoms
  • Need for imaging studies to confirm diagnosis

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to differentiate from endometriosis or other cysts
  • Lack of imaging results in the medical record
  • Incorrect coding based on incomplete clinical information

Frequently Asked Questions

What is the typical treatment for a corpus luteum cyst?

Most corpus luteum cysts resolve on their own without treatment. However, if they cause significant pain or complications, hormonal therapy or surgical intervention may be considered.
