About J37

J37 is the ICD-10-CM diagnosis code for chronic laryngitis and laryngotracheitis. It belongs to block J30-J39 (other diseases of upper respiratory tract) 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.

To report this condition, pick the subcode that matches the documentation: J37.0 (laryngitis) and J37.1 (laryngotracheitis).

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), infectious agent (B95-B97), occupational exposure to environmental tobacco smoke (Z57.31) and 2 more.

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