N45 Orchitis and epididymitis

Name of the Condition

• Orchitis and epididymitis

Summary

Orchitis and epididymitis are inflammatory conditions affecting the testicle (orchitis) and the epididymis (epididymitis), respectively. These conditions often occur together (epididymo-orchitis) and are typically caused by infections, leading to pain, swelling, and potential complications if untreated. The inflammation can result from bacterial or viral sources, with sexually transmitted infections being a common cause in younger adults.

Causes

Orchitis and epididymitis are most frequently caused by bacterial infections, including sexually transmitted infections (e.g., gonorrhea, chlamydia) or urinary tract infections. Viral infections, such as mumps, can also lead to orchitis. Less commonly, non-infectious causes like trauma, autoimmune reactions, or chemical irritation may contribute to inflammation.

Risk Factors

• Being sexually active, particularly with multiple partners or unprotected intercourse, increases the risk of sexually transmitted infections that can cause these conditions.
• A history of urinary tract infections or recent urinary tract procedures may elevate risk.
• Age (younger men are more prone to sexually transmitted causes, while older men may have infections related to prostate enlargement).
• Immunocompromised states or recent mumps infection can predispose to viral orchitis.

Symptoms

• Pain and swelling in the scrotum, often localized to the testicle or epididymis.
• Tenderness or warmth in the affected area.
• Fever, chills, or general malaise.
• Pain during urination or ejaculation.
• Discharge from the penis (in cases of sexually transmitted infections).
• Redness or skin changes over the scrotum.

Diagnosis

Diagnosis involves a physical examination to assess scrotal swelling and tenderness, along with patient history to identify potential causes (e.g., recent infections or sexual activity). Urine tests (urinalysis or culture) may detect bacterial infections, while blood tests can check for signs of inflammation (e.g., elevated white blood cells). Imaging, such as ultrasound, may be used to rule out other conditions like testicular torsion or abscesses.

Treatment Options

Treatment depends on the underlying cause. Bacterial infections are treated with antibiotics, tailored to the suspected pathogen. Anti-inflammatory medications (e.g., NSAIDs) reduce pain and swelling. Supportive care includes scrotal elevation, cold compresses, and rest. For viral orchitis (e.g., mumps), treatment focuses on symptom relief, as antibiotics are ineffective. Sexual partners may need evaluation and treatment if a sexually transmitted infection is identified.

Prognosis and Follow-Up

With prompt treatment, most cases resolve without long-term complications. Pain and swelling typically improve within days to weeks. Follow-up may involve repeat testing to ensure infection clearance and monitoring for recurrence. Untreated or severe cases can lead to complications, requiring ongoing care.

Complications

• Abscess formation in the scrotum or testicle.
• Chronic pain or infertility due to scarring of the epididymis or testicle.
• Spread of infection to the bloodstream (sepsis) in rare cases.
• Testicular atrophy (shrinkage) from prolonged inflammation.

Lifestyle & Prevention

• Practice safe sex (e.g., condom use) to reduce sexually transmitted infection risk.
• Maintain good hygiene and promptly treat urinary tract infections.
• Stay up-to-date with mumps vaccination to prevent viral orchitis.
• Avoid activities that may cause scrotal trauma.

When to Seek Professional Help

Seek medical attention if you experience sudden or severe scrotal pain, fever, or swelling, as these may indicate a serious infection or other conditions like testicular torsion. Persistent symptoms after initial treatment or signs of worsening (e.g., increasing pain, discharge) also warrant evaluation.

Tips for Medical Coders

When coding for orchitis and epididymitis (ICD-10-CM code N45), ensure documentation specifies whether the condition affects the testicle (orchitis), epididymis (epididymitis), or both (epididymo-orchitis). Note the underlying cause (e.g., infectious vs. non-infectious) if available, as this may influence coding specificity. For bilateral involvement, additional documentation may be required to support appropriate code assignment.
