An abnormal growth in the area around the uterus, including the ovaries and fallopian tubes.
Often asymptomatic. May present with pelvic pain, bloating, or menstrual changes. Requires imaging for diagnosis.
Gynecology clinics, primary care offices, emergency rooms for acute pain or torsion.

When to use each related code
| Description | When to use |
|---|---|
| Growth near uterus, often ovary. | Use for unspecified mass in adnexal region. Consider ovarian or pelvic mass if location is clear. |
| Mass arising from the ovary. | Use when mass is confirmed to be ovarian. Rule out other pelvic masses like fibroids. |
| Abnormal growth in the pelvis. | Use when location is pelvic but not specifically ovarian or uterine. Investigate organ of origin. |
Best-practice checklist
- ✓Adnexal mass laterality (left, right, bilateral)
- ✓Mass size (cm), measured via imaging
- ✓Palpable on exam? Location/mobility details
- ✓Ultrasound characteristics: simple vs. complex
- ✓Symptoms: pain, bloating, pressure, abnormal bleeding
Common pitfalls to avoid
Missing documentation specifying whether the adnexal mass is on the right, left, or bilateral side, impacting accurate coding.
Using a generic term like 'adnexal mass' instead of a more definitive diagnosis if known (e.g., cyst, tumor) can lead to coding errors.
Coding a suspected or probable diagnosis as confirmed without clear documentation of confirmation can cause inaccurate reporting.
Best-practice tips
- 01ICD-10 N83.2, clear laterality documentation for adnexal mass.
- 02CPT coding: pelvic US for diagnosis, surgical codes if removed.
- 03CDI: specify mass type, size, location, complexity for accurate billing.
- 04HCC coding: document associated symptoms, consider malignancy (C56).
- 05Compliance: detailed operative report if surgery performed, pathology report.
Step-by-step checklist
- 1
Confirm laterality (right, left, bilateral) and document precisely.
- 2
Characterize mass (cystic, solid, complex) using imaging results.
- 3
Assess CA-125 levels and document, especially if >35 U/mL.
- 4
Evaluate for pelvic pain, bloating, abnormal bleeding, and document.
- 5
Rule out other diagnoses (ectopic pregnancy, fibroids) and document.
Ready-to-paste narrative
Patient presents with concerns regarding a possible adnexal mass. Presenting symptoms include pelvic pain, bloating, abdominal distension, and irregular menses. Differential diagnoses considered include ovarian cyst, adnexal torsion, ectopic pregnancy, pelvic inflammatory disease, and other gynecological malignancies. Physical examination revealed tenderness in the adnexal region. Pelvic ultrasound was performed, demonstrating a complex adnexal mass measuring [size] cm. CA-125 levels were drawn. Patient was counseled on the possible diagnoses and treatment options, including watchful waiting with repeat ultrasound, surgical intervention such as laparoscopy or laparotomy, and medical management depending on the final diagnosis. The patient's medical history includes [relevant medical history, e.g., prior pregnancies, surgeries, gynecological conditions]. Family history is significant for [relevant family history, e.g., ovarian cancer, breast cancer]. The patient was advised to return for follow-up in [timeframe] to discuss results and further management. ICD-10 code N73.9 (Female pelvic mass, unspecified) is provisionally assigned, pending definitive diagnosis. This may be updated based on further investigation and pathology results if surgical intervention is pursued. Further evaluation is required to determine the etiology of the adnexal mass and guide appropriate treatment.
Common questions and answers
What is the optimal diagnostic workup for an adnexal mass in a premenopausal woman, considering both benign and malignant differentials?+
The optimal diagnostic workup for an adnexal mass in a premenopausal woman should consider the wide range of potential diagnoses, from benign physiological cysts to malignant ovarian neoplasms. Initial assessment includes a thorough pelvic exam combined with transvaginal ultrasound to characterize the mass (size, morphology, complexity). Serum CA-125 levels can be helpful, particularly in postmenopausal women, but have limitations in premenopausal patients due to lower specificity. Risk stratification models, such as the RMI (risk of malignancy index), incorporating ultrasound findings and CA-125, can aid in risk assessment. For complex masses or those with concerning features, further imaging with MRI may be warranted. Consider implementing a multidisciplinary approach involving gynecologic oncologists for suspected malignancy. Explore how risk stratification tools and advanced imaging modalities can enhance the accuracy of adnexal mass evaluation. If surgical intervention is considered, referral to a gynecologic oncologist is crucial for optimal management.
How can I differentiate a simple ovarian cyst from a more concerning adnexal mass requiring urgent gynecologic oncology referral?+
Differentiating a simple ovarian cyst from a more concerning adnexal mass relies on a combination of clinical findings and imaging characteristics. Simple cysts typically appear anechoic on ultrasound, with thin, smooth walls and no internal septations or solid components. Conversely, features suggestive of malignancy include thick septations, solid components, papillary projections, increased vascularity on Doppler, and ascites. Size alone is not always a reliable indicator, but larger masses, especially those rapidly growing, warrant closer scrutiny. Elevated CA-125, while not definitive, adds to suspicion. Clinicians should maintain a high index of suspicion for any adnexal mass in postmenopausal women. Learn more about the specific ultrasound characteristics that differentiate benign from malignant adnexal masses to ensure prompt and appropriate referrals. If any doubt exists, urgent gynecologic oncology consultation is recommended, as early diagnosis and intervention significantly impact outcomes for ovarian cancer.
What are the recommended management strategies for an adnexal mass in a pregnant patient, balancing maternal and fetal risks?+
Managing adnexal masses in pregnancy presents unique challenges, requiring careful consideration of both maternal and fetal well-being. The majority of adnexal masses discovered during pregnancy are benign and often resolve spontaneously. Transvaginal ultrasound is the preferred imaging modality, although MRI can be used if necessary. Expectant management with serial ultrasounds is often appropriate for asymptomatic simple cysts. However, complex masses, solid components, or those causing symptoms necessitate further evaluation. Surgical intervention, if required, is ideally performed during the second trimester to minimize risks. Explore how a multidisciplinary team involving maternal-fetal medicine specialists and gynecologic oncologists can provide comprehensive care for pregnant women with adnexal masses. Consider implementing a shared decision-making approach with the patient, weighing the risks and benefits of intervention during pregnancy.
