About coding urethritis
The ICD-10-CM code for urethritis is N34.2 (Other urethritis). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N34.2.
Within N34, choose N34.2 (Other urethritis) only when documentation doesn't support a more specific option: urethral abscess (N34.0), nonspecific urethritis (N34.1) and urethral syndrome, unspecified (N34.3).
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.
