About J01

J01 is the ICD-10-CM diagnosis code for acute sinusitis. It belongs to 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: J01.0 (sinusitis), J01.1 (sinusitis), J01.2 (sinusitis), J01.3 (sinusitis), J01.4 (pansinusitis), J01.8 (sinusitis) and J01.9 (unspecified).

Don't report J01 together with the conditions in its Excludes1 note: sinusitis NOS (J32.9).

The conditions in its Excludes2 note aren't part of J01, but may be coded alongside it if the patient has both: chronic sinusitis (J32.0-J32.8).

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.
