N83.5 Torsion of ovary, ovarian pedicle and fallopian tube

Name of the Condition

• Torsion of Ovary, Ovarian Pedicle, and Fallopian Tube
  
  • Also known as adnexal torsion, this condition involves the twisting of the ovary, its supporting structures, and the fallopian tube.

Summary

Ovarian torsion is a medical emergency where the ovary and fallopian tube twist around their vascular and ligamentous supports, compromising blood flow. Prompt diagnosis and treatment are critical to preserve ovarian function and prevent complications.

Causes

The exact cause is often unclear, but potential triggers include ovarian cysts, masses, or hypermobility of the reproductive organs. Pregnancy, fertility treatments, or anatomical variations may also contribute to the risk of torsion.

Risk Factors

• Females of reproductive age, especially those undergoing fertility treatments
• Presence of ovarian cysts or masses
• Polycystic ovarian syndrome (PCOS)
• History of prior torsion or pelvic surgery
• Hormonal therapies or assisted reproductive technologies

Symptoms

• Sudden, severe unilateral pelvic pain
• Nausea and vomiting
• Abdominal tenderness or distension
• Low-grade fever (in advanced cases)
• Possible vaginal bleeding or discharge

Diagnosis

Transvaginal ultrasound with Doppler imaging to assess blood flow to the ovary. Physical pelvic examination to evaluate tenderness and masses. MRI or CT scans may be used to confirm diagnosis in unclear cases. Laboratory tests to rule out other conditions (e.g., infection, ectopic pregnancy)

Treatment Options

• Surgical intervention (laparoscopy or laparotomy) to untwist the structures and restore blood flow. If the ovary is nonviable, removal (oophorectomy) may be necessary.
• Pain management with analgesics and antiemetics during stabilization.
• Conservative management (e.g., bed rest, observation) may be considered in select cases with minimal symptoms and preserved blood flow.

Prognosis and Follow-Up

Early treatment generally yields a good prognosis with preservation of ovarian function. Delayed intervention increases the risk of ovarian necrosis and infertility. Follow-up may include imaging to monitor ovarian viability and fertility assessments if needed.

Complications

• Ovarian necrosis or infarction
• Infertility due to loss of ovarian tissue
• Infection or abscess formation
• Recurrence of torsion

Lifestyle & Prevention

• Avoid strenuous activity if ovarian cysts or masses are present.
• Promptly address pelvic pain or symptoms suggestive of torsion.
• Regular gynecological evaluations to monitor reproductive health.

When to Seek Professional Help

• Sudden, severe pelvic pain, especially with nausea or vomiting.
• Persistent abdominal pain or tenderness.
• Signs of infection (e.g., fever, chills).

Tips for Medical Coders

• Code N83.5 is specific to torsion of the ovary, ovarian pedicle, and fallopian tube. Ensure documentation supports the diagnosis, including clinical findings (e.g., pain, imaging results) and any surgical or conservative management. Avoid coding for related but distinct conditions (e.g., isolated fallopian tube torsion) without clear differentiation.
