Benign Cystic Ovarian Mass
Understand Benign Cystic Ovarian Mass (ICD-10 codes: N83.0-N83.2, D27). This guide covers ovarian cyst diagnosis, benign ovarian neoplasm workup, and clinical documentation best practices for healthcare professionals. Learn about differential diagnosis, medical coding for ovarian cysts, and treatment options. Find information relevant to healthcare providers, medical coders, and clinicians.
Fluid-filled sacs in or on an ovary, usually noncancerous.
Often asymptomatic. May cause pelvic pain, bloating, irregular periods, or pain during intercourse.
Gynecology clinics, primary care offices, emergency rooms for ruptured cysts.

When to use each related code
| Description | When to use |
|---|---|
| Fluid-filled sacs on the ovary, often asymptomatic. | Use for simple cysts, functional cysts, and other non-cancerous masses. Exclude if complex features present. |
| Non-cancerous ovarian tumors including teratomas and cystadenomas. | Use for solid or complex ovarian masses with benign characteristics on imaging. Histopathology confirmation recommended. |
| Malignant ovarian tumors with potential for spread. | Use for ovarian masses with suspicious features on imaging or biopsy suggesting cancer. Refer to oncology. |
Best-practice checklist
- ✓Ovarian cyst size, location, and characteristics documented.
- ✓Symptoms, such as pelvic pain or bloating, clearly described.
- ✓Imaging results (e.g., ultrasound, CT) specifying cyst type.
- ✓Differential diagnosis considerations for ovarian masses noted.
- ✓Management plan, including observation or surgical intervention, detailed.
Common pitfalls to avoid
Documentation lacks clarity on whether the cyst affects the right, left, or both ovaries, impacting code selection (e.g., N28.1 vs. N28.0).
Missing details on the specific cyst type (e.g., follicular, corpus luteum) may prevent accurate coding and affect reimbursement.
Failing to document if the cyst is ruptured or intact can lead to incorrect coding, as specific codes exist for ruptured cysts (e.g., N28.2).
Best-practice tips
- 01ICD-10 N83.2 accurate coding for ovarian cyst
- 02Detailed pelvic exam documentation for CDI
- 03Monitor cyst size, resolve coding queries
- 04Patient education on ovarian cyst management
- 05Compliance: document informed consent for procedures
Step-by-step checklist
- 1
Confirm patient age, menstrual history, and symptoms (pelvic pain, bloating).
- 2
Review ultrasound findings: simple cyst, unilocular, thin walls, no solid components.
- 3
Check CA-125 levels (if age-appropriate) to assess risk of malignancy.
- 4
Exclude ectopic pregnancy with beta-hCG test if premenopausal.
Ready-to-paste narrative
Patient presents with complaints consistent with possible benign cystic ovarian mass, including pelvic pain, abdominal bloating, and irregular menstrual cycles. Differential diagnosis includes ovarian cyst, benign ovarian neoplasm, functional ovarian cyst, polycystic ovary syndrome (PCOS), and endometriosis. Physical examination reveals tenderness on palpation of the adnexa. Pelvic ultrasound was performed demonstrating a unilocular, thin-walled cystic structure on the right ovary measuring 4 cm in diameter, suggestive of a simple ovarian cyst. Laboratory tests including complete blood count (CBC), comprehensive metabolic panel (CMP), and CA-125 tumor marker were ordered and resulted within normal limits, further supporting the diagnosis of a benign process. Patient was counseled on expectant management with repeat ultrasound in 8-12 weeks to assess for resolution. Diagnosis codes considered include ICD-10 N76.0 (benign cyst of ovary) and N83.20 (ovarian cyst, unspecified, not elsewhere classified). Medical billing will reflect the evaluation and management (E/M) services provided, along with the diagnostic testing performed. Patient education regarding ovarian cysts, symptoms, and potential complications was provided, emphasizing the importance of follow-up care. The patient verbalized understanding of the treatment plan and was advised to return for further evaluation if symptoms worsen or new symptoms develop.
Common questions and answers
What are the key differentiating factors in the diagnostic workup of a simple ovarian cyst vs. a benign cystic ovarian neoplasm requiring surgical intervention?+
Differentiating a simple ovarian cyst from a benign cystic ovarian neoplasm requiring surgery relies on a combination of clinical presentation, imaging characteristics, and tumor marker evaluation. Simple cysts are typically asymptomatic, anechoic on ultrasound, and resolve spontaneously. However, features like increasing size (>5-7cm), complex morphology (septations, solid components), or persistent symptoms warrant further investigation. Serum CA-125 can be helpful, especially in postmenopausal women, but it's not specific to malignancy. Consider implementing a risk stratification model incorporating these factors to guide management. Explore how RMI risk score calculator aids in decision-making for ovarian cysts.
How can I best manage a premenopausal patient with a suspected benign cystic ovarian mass and persistent pelvic pain despite conservative management?+
Managing premenopausal patients with persistent pelvic pain despite conservative measures for a suspected benign cystic ovarian mass requires a thorough evaluation to rule out other causes of pain. Consider a detailed history, physical examination, and imaging studies like pelvic ultrasound or MRI to characterize the mass and assess for other pelvic pathologies like endometriosis or pelvic inflammatory disease. If the pain is directly attributable to the ovarian mass (e.g., torsion, rupture), laparoscopic cystectomy may be indicated. For chronic pain associated with a persistent cyst, explore how hormonal contraceptives may impact cyst size and symptom control. Learn more about the role of laparoscopic surgery in managing symptomatic ovarian cysts.
When should I refer a patient with a benign cystic ovarian mass to a gynecologic oncologist for expert opinion and potential surgical management?+
Referral to a gynecologic oncologist is recommended for benign cystic ovarian masses with suspicious features raising concern for malignancy. These include rapid growth, complex morphology on imaging (solid components, thick septations, ascites), elevated or rising tumor markers (especially CA-125 in postmenopausal women), or family history of ovarian cancer. While most benign masses can be managed by a general gynecologist, the expertise of a gynecologic oncologist is crucial in cases with concerning features or when surgical complexity is anticipated. Consider implementing a referral pathway for ovarian masses based on risk stratification. Explore how current guidelines on ovarian cyst management can improve referral practices.
