About H04.30

H04.30 is the ICD-10-CM diagnosis code for unspecified dacryocystitis. It belongs to category H04 (disorders of lacrimal system), 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 4 subcodes must be used instead.

Within H04.3, choose H04.30 (Unspecified dacryocystitis) only when documentation doesn't support a more specific option: Phlegmonous dacryocystitis (H04.31), acute dacryocystitis (H04.32) and acute lacrimal canaliculitis (H04.33).

To report this condition, pick the subcode that matches the documentation: H04.301 (of right lacrimal passage), H04.302 (of left lacrimal passage), H04.303 (of bilateral lacrimal passages) and H04.309 (of unspecified lacrimal passage).

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