About coding Antritis
The ICD-10-CM code for Antritis is J32.0 (Chronic maxillary sinusitis). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J32.0.
Within J32 (chronic sinusitis), J32.0 is specifically for chronic maxillary sinusitis. Related codes cover chronic frontal sinusitis (J32.1), chronic ethmoidal sinusitis (J32.2), chronic sphenoidal sinusitis (J32.3), chronic pansinusitis (J32.4), other chronic sinusitis (J32.8) and unspecified (J32.9).
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.
