About coding orchitis
The ICD-10-CM code for orchitis is N45.2 (Orchitis). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N45.2.
Within N45 (orchitis and epididymitis), N45.2 is specifically for orchitis. Related codes cover epididymitis (N45.1), epididymo-orchitis (N45.3) and abscess of epididymis or testis (N45.4).
Use an additional code (B95-B97), to identify infectious agent.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
