ICD-10 Code for Ovarian Cyst

Understanding the details of diagnostic codes is essential in the always changing world of healthcare and medical coding. When it comes to appropriately recording and accounting for this frequent gynaecological illness, the ICD-10 code for ovarian cyst is one of the most important. The significance, use, and ramifications of this particular code for both medical professionals and patients will be clarified as we dig into its depths in this extensive book.

What is the ICD-10 Code for Ovarian Cyst?

The International Classification of Diseases, 10th Edition, commonly referred to as ICD-10, is a standardized system used worldwide for classifying medical diagnoses. It assigns a unique code to each medical condition, ensuring precise communication between healthcare providers, insurance companies, and researchers. When it comes to ovarian cysts, the specific ICD-10 code you should be familiar with is N83.20.

Understanding the Code: N83.20

Let’s break down this code to understand its components and significance:

  • N: This letter represents the category of the disease. In this case, “N” stands for diseases of the genitourinary system.
  • 83: The digits following the category letter represent the subcategory. In the ICD-10 system, ovarian cysts fall under subcategory 83.
  • 20: The final two digits provide further specificity within the subcategory. For ovarian cysts, the code 20 is used to designate an unspecified ovarian cyst.

Accurate Diagnosis and Treatment

Accurate coding of medical conditions, such as ovarian cysts, is paramount for healthcare professionals. It ensures that patients receive appropriate treatment and that insurance claims are processed correctly. When a healthcare provider assigns the ICD-10 code N83.20 for an ovarian cyst diagnosis, it clearly communicates the nature of the condition to insurance companies, facilitating a smoother claims process.

Research and Data Analysis

Medical coding is essential for data analysis and research in the field of medicine. Researchers can track the prevalence of ovarian cysts, examine trends, and get insights into the treatment and results of the condition by using coded data. This ultimately leads to improvements in patient treatment and the growth of medical knowledge.

Billing and Reimbursement

Correct billing and reimbursement for healthcare facilities are made possible by accurate coding. The right ICD-10 code needs to be used in order to accurately bill insurance companies for ovarian cysts. By ensuring that healthcare workers receive equitable pay for their labor, it helps to preserve the caliber of care that they provide to patients.

Ovarian Cyst: An Overview

Ovarian cysts are fluid-filled sacs that can develop either inside or outside the ovaries. These cysts commonly appear in women of all ages and might differ in size, appearance, and symptoms. While most ovarian cysts are benign and disappear on their own, some may require medical attention.

Types of Ovarian Cysts

Ovarian cysts can in a variety of forms, including:

  1. Functional Cysts: These cysts are the most common and typically develop as part of the menstrual cycle. Usually, they go away on their own after a few menstrual cycles.
  2. Dermoid Cysts: Dermoid cysts are filled with various types of tissues, including hair and skin. They are usually benign but may require surgical removal.
  3. Endometriomas: These cysts form when endometrial tissue grows within the ovaries. They could disrupt fertility and be unpleasant.
  4. Cystadenomas: Cystadenomas are filled with a watery or mucus-like substance and can grow quite large. While usually benign, they may require surgical removal if they become too large or cause discomfort.

How Is Ovarian Cyst Diagnosed?

The diagnosis of an ovarian cyst typically involves a combination of the following:

Medical History: A thorough medical history is taken to understand the patient’s symptoms, any relevant medical conditions, and family history.

Physical Examination: A physical examination may reveal tenderness or swelling in the lower abdomen. During this examination, the healthcare provider may also perform a pelvic exam.

Imaging Tests: To confirm the presence of an ovarian cyst and gather more information about its size and characteristics, the following imaging tests may be used:

  • Ultrasound: This non-invasive test uses sound waves to create images of the ovaries and cysts.
  • CT Scan: A computed tomography (CT) scan provides detailed cross-sectional images, aiding in diagnosis.
  • MRI: Using magnetic resonance imaging (MRI), more details regarding the cyst’s makeup can be obtained.

Blood Tests: The likelihood of the cyst being malignant may be assessed using blood testing, such as CA-125, however this is not conclusive.

Treatment Options for Ovarian Cysts

The method used to treat ovarian cysts relies on a number of variables, such as the cyst’s size, kind, and if it is producing symptoms. Treatment choices might be:

Watchful Waiting

For small, asymptomatic cysts, healthcare providers may recommend a “watch and wait” approach. This involves regular monitoring to ensure the cyst does not grow or cause symptoms.


Hormonal birth control pills are sometimes prescribed to prevent new cysts from forming or to shrink existing ones. Pain relievers may also be recommended for discomfort.

Surgical Intervention

If a cyst is large, painful, or suspected to be cancerous, surgery may be necessary. There are two primary surgical approaches:

  • Laparoscopy: This minimally invasive procedure involves making small incisions and using a tiny camera to guide the removal of the cyst.
  • Laparotomy: In some cases, a larger incision may be required to remove the cyst, especially if it is large or cancerous.


It is essential to comprehend the N83.20 ICD-10 code for ovarian cysts when it comes to medical coding and healthcare. This code makes accurate diagnosis, treatment, research, and billing possible, guaranteeing that patients and healthcare professionals get the greatest support and care possible.

Despite being frequent, ovarian cysts can differ in complexity and severity. You must consult a doctor right away if you think you have an ovarian cyst or if you have symptoms like pelvic discomfort. Your healthcare professional can make a diagnosis, suggest the best course of action, and guarantee your wellbeing.
