About coding Supraglottitis
The ICD-10-CM code for Supraglottitis is J04.30 (Supraglottitis, unspecified, without obstruction). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on J04.30.
Within J04.3, choose J04.30 (without obstruction) only when documentation doesn't support a more specific option: with obstruction (J04.31).
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.
