About J70

J70 is the ICD-10-CM diagnosis code for respiratory conditions due to other external agents. It belongs to block J60-J70 (lung diseases due to external agents) and chapter 10 (diseases of the respiratory system). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: J70.0 (radiation), J70.1 (radiation), J70.2 (disorders), J70.3 (disorders), J70.4 (unspecified), J70.5 (inhalation), J70.8 (agents) and J70.9 (agent).

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