About J98

J98 is the ICD-10-CM diagnosis code for other respiratory disorders. It belongs to block J96-J99 (other diseases of the respiratory system) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: J98.0 (classified), J98.1 (collapse), J98.2 (emphysema), J98.3 (emphysema), J98.4 (lung), J98.5 (classified), J98.6 (diaphragm), J98.8 (disorders) and 1 more.

Don't report J98 together with the conditions in its Excludes1 note: newborn apnea (P28.4-) and newborn sleep apnea (P28.3-).

The conditions in its Excludes2 note aren't part of J98, but may be coded alongside it if the patient has both: apnea NOS (R06.81) and sleep apnea (G47.3-).

Use an additional code to identify: exposure to environmental tobacco smoke (Z77.22), exposure to tobacco smoke in the perinatal period (P96.81), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and 1 more.

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