Orchitis

This code represents an acute inflammatory condition affecting the testis, characterized by sudden onset of testicular pain, swelling, and tenderness. It is often associated with systemic symptoms such as fever and malaise, and can be infectious or non-infectious in origin.

Use this code when documentation clearly indicates a diagnosis of acute orchitis. This typically includes physician notes detailing the acute onset of symptoms, physical examination findings consistent with testicular inflammation, and potentially laboratory results supporting an inflammatory process.

• Differentiate from epididymitis (N45.3) or epididymo-orchitis (N45.4) based on documentation of the primary site of inflammation.
• If an infectious agent is identified, code the infection first, followed by this code.
• Ensure the laterality (left, right, bilateral) is not specified, as this code represents unspecified laterality.
