About J01.4

J01.4 is the ICD-10-CM diagnosis code for acute pansinusitis. It belongs to category J01 (acute sinusitis), block J00-J06 (acute upper respiratory infections) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within J01 (acute sinusitis), J01.4 is specifically for acute pansinusitis. Related codes cover acute maxillary sinusitis (J01.0), acute frontal sinusitis (J01.1), acute ethmoidal sinusitis (J01.2), acute sphenoidal sinusitis (J01.3), other acute sinusitis (J01.8) and unspecified (J01.9).

To report this condition, pick the subcode that matches the documentation: J01.40 (unspecified) and J01.41 (pansinusitis).

Use an additional code (B95-B97) to identify infectious agent.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
