About coding vesiculitis
The ICD-10-CM code for vesiculitis is N49.0 (Inflammatory disorders of seminal vesicle). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N49.0.
Within N49 (inflammatory disorders of male genital organs, not elsewhere classified), N49.0 is specifically for inflammatory disorders of seminal vesicle. Related codes cover inflammatory disorders of spermatic cord, tunica vaginalis and vas deferens (N49.1), inflammatory disorders of scrotum (N49.2), Fournier gangrene (N49.3), inflammatory disorders of other specified male genital organs (N49.8) and inflammatory disorder of unspecified male genital organ (N49.9).
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.
