About coding testis infectional gangrene
The ICD-10-CM code for testis infectional gangrene is N45.2 (Orchitis). The official index lists 1 more specific code, 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.
