About coding nasal abscess
The ICD-10-CM code for nasal abscess is J32.9 (Chronic sinusitis, unspecified).
Within J32, choose J32.9 (unspecified) only when documentation doesn't support a more specific option: chronic maxillary sinusitis (J32.0), chronic frontal sinusitis (J32.1), chronic ethmoidal sinusitis (J32.2), chronic sphenoidal sinusitis (J32.3), chronic pansinusitis (J32.4) and other chronic sinusitis (J32.8).
Use an additional code to identify: infectious agent (B95-B97).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
