About coding membranous angina
The ICD-10-CM code for membranous angina is J05.0 (Acute obstructive laryngitis [croup]). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J05.0.
Within J05 (acute obstructive laryngitis [croup] and epiglottitis), J05.0 is specifically for acute obstructive laryngitis [croup]. Related codes cover epiglottitis (J05.1).
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.
