About H04

H04 is the ICD-10-CM diagnosis code for disorders of lacrimal system. It belongs to block H00-H05 (disorders of eyelid, lacrimal system and orbit) and chapter 7 (diseases of the eye and adnexa). 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: H04.0 (dacryoadenitis), H04.1 (gland), H04.2 (epiphora), H04.3 (passages), H04.4 (passages), H04.5 (passages), H04.6 (passages), H04.8 (system) and 1 more.

Don't report H04 together with the conditions in its Excludes1 note: congenital malformations of lacrimal system (Q10.4-Q10.6).

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