Mumps orchitis

This code represents inflammation of one or both testicles caused by the mumps virus. It is a common complication of mumps, particularly in post-pubertal males, and can lead to testicular atrophy and infertility.

Assign this code when documentation explicitly states a diagnosis of orchitis due to a mumps infection. This typically occurs in a patient presenting with symptoms of mumps (e.g., parotitis) followed by testicular pain and swelling.

• Ensure documentation specifies mumps as the causative agent for orchitis; otherwise, a non-mumps orchitis code would be more appropriate.
• Consider sequencing this code after the primary mumps infection code (e.g., 072.9) if the orchitis is a complication.
• Do not use this code for orchitis due to bacterial infections or other viral etiologies.
