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