Ovarian Cysts: A Guide to ICD-10 Coding and Patient Care

Ovarian cysts are fluid-filled sacs that develop on or within an ovary. They are quite common, affecting women of all ages, though they are most prevalent during childbearing years. There are various types of ovarian cysts, some harmless and others requiring medical attention. This article explores the world of ovarian cysts, specifically focusing on the relevant ICD-10 code for diagnosis and providing guidance for optimal patient care.

Anatomy and Physiology

The ovaries, a pair of almond-shaped organs located on either side of the uterus, play a crucial role in the menstrual cycle and ovulation. Each month, follicles containing immature eggs develop within the ovaries. During ovulation, one of these follicles matures, releasing a mature egg (oocyte) into the fallopian tube, where it can be fertilized by sperm.

Types of Ovarian Cysts

There are several types of ovarian cysts, categorized based on their origin and content:

  • Functional cysts: These are the most common type, arising from the normal hormonal fluctuations of the menstrual cycle. They typically disappear on their own within a few months. There are two main subtypes:
    • Follicle cysts: Develop when a follicle fails to release an egg during ovulation.
    • Corpus luteum cysts: Form from the remnants of a follicle after ovulation has occurred.
  • Endometriomas: These cysts are associated with endometriosis, a condition where endometrial tissue, the tissue that normally lines the uterus, grows outside the uterus. Endometriomas can cause pain and may impact fertility.
  • Dermoid cysts: These contain a mixture of tissues such as hair, skin, or teeth, a remnant of embryonic development.
  • Cystadenomas: These are benign epithelial tumors that can be serous (fluid-filled), mucinous (mucus-filled), or of mixed type.
  • Brenner tumors: These are rare and usually benign but can sometimes be malignant.

Symptoms and Diagnosis

Ovarian cysts often present no symptoms and are discovered incidentally during a pelvic exam or ultrasound for another reason. However, some women may experience:

  • Pelvic pain, ranging from dull to sharp
  • Bloating
  • Irregular periods
  • Painful intercourse
  • Difficulty becoming pregnant

Diagnosis of an ovarian cyst typically involves a combination of:

  • Pelvic exam: To assess the size, location, and tenderness of the ovaries.
  • Ultrasound: A painless procedure using sound waves to visualize the cyst’s characteristics.
  • Blood tests: May be used to check for pregnancy or certain tumor markers.
  • MRI (magnetic resonance imaging): In some cases, an MRI may be used to obtain a clearer picture of the cyst and surrounding structures.

ICD-10 Coding for Ovarian Cysts

The International Classification of Diseases, Tenth Revision (ICD-10), is a standardized system for coding diagnoses and medical procedures. The specific ICD-10 code for an ovarian cyst depends on the type of cyst:

  • N83.20: Unspecified ovarian cysts: This is the most commonly used code for ovarian cysts when the specific type is unknown or not documented. There are further subcategories to specify laterality (right, left, or unspecified side).
  • N83.00: Follicle cyst: Code for a cyst arising from a non-ovulated follicle.
  • N83.10: Corpus luteum cyst: Code for a cyst formed from the remnants of a corpus luteum.
  • N83.8 Other ovarian cysts: This category includes endometriomas, dermoid cysts, cystadenomas, and Brenner tumors. Specific codes within this category further classify the type of cyst.

Treatment Options

The treatment approach for an ovarian cyst depends on several factors, including the type, size, and symptoms. Often, no treatment is necessary for small, functional cysts that are likely to resolve on their own. However, in some cases, treatment may be recommended, such as:

  • Observation: Regularly monitoring the cyst with pelvic exams and ultrasounds to ensure it doesn’t grow or become problematic.
  • Hormonal birth control: Can help regulate ovulation and prevent new cyst formation.
  • Surgery: Laparoscopic surgery is a minimally invasive option for removing cysts, particularly larger ones or those suspected to be cancerous. In some cases, an ovary may need to be removed (oophorectomy).

Ovarian Cysts: A Guide to ICD-10 Coding and Patient Care

Ovarian cysts are fluid-filled sacs that develop on the ovaries, and they can vary in size and cause symptoms like pelvic pain, bloating, and changes in menstrual cycles. Proper coding and patient care are essential for managing this condition effectively.

  • Address emotional concerns: Acknowledge the patient’s anxieties and provide support. Discuss potential impact on fertility if applicable.
  • Develop a personalized care plan: Tailor the approach based on the individual’s circumstances and preferences.
  • Ensure clear communication: Maintain open communication channels to address any questions or concerns throughout the process.
  • Follow-up care: Schedule regular follow-up appointments to monitor the cyst and ensure a successful outcome.


A common ailment that affects women of all ages is ovarian cysts. While most are benign and resolve independently, some require medical attention. Understanding the different types of cysts, their diagnosis with relevant ICD-10 coding, and available treatment options empowers women to make informed decisions about their healthcare.  Effective patient communication, emotional support, and personalized care plans are essential for optimal outcomes. Remember, consulting a healthcare professional is vital for proper diagnosis and management of any ovarian cyst concerns.
