Code Description

ICD-10 N45 is a billable code used to indicate a diagnosis of orchitis and epididymitis.

Key Diagnostic Point:

Orchitis and epididymitis refer to the inflammation of the testis and the epididymis, respectively. Orchitis can occur as a result of viral infections, such as mumps, or bacterial infections, often associated with sexually transmitted infections (STIs) like gonorrhea and chlamydia. Epididymitis is frequently caused by similar pathogens and can present with acute or chronic symptoms. Patients typically experience scrotal pain, swelling, and tenderness, which may be accompanied by fever and dysuria. In some cases, these conditions can lead to complications such as abscess formation, testicular necrosis, or infertility due to damage to the reproductive structures. The management of orchitis and epididymitis often involves antibiotics for bacterial infections, pain management, and supportive care. In cases of hydrocele, which is the accumulation of fluid around the testis, surgical intervention may be necessary if symptomatic. Understanding the underlying causes and associated conditions is crucial for effective treatment and management of male infertility and other testicular disorders.

  • Differentiating between viral and bacterial causes
  • Identifying associated conditions like hydrocele
  • Understanding the implications for male infertility
  • Documenting the severity and duration of symptoms

Audit Risk Factors

  • Inadequate documentation of causative agents
  • Failure to specify acute vs. chronic conditions
  • Misclassification of orchitis as a testicular disorder
  • Omission of associated conditions like hydrocele

Frequently Asked Questions

What are the common causes of orchitis and epididymitis?

Common causes include viral infections like mumps and bacterial infections such as those caused by gonorrhea and chlamydia. Other factors may include trauma or autoimmune conditions.

How can orchitis and epididymitis affect male fertility?

Both conditions can lead to complications such as testicular atrophy or damage to the reproductive structures, potentially impacting fertility. Early diagnosis and treatment are crucial.
