About H04.55
H04.55 is the ICD-10-CM diagnosis code for acquired stenosis of nasolacrimal duct. 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 H04.5 (stenosis and insufficiency of lacrimal passages), H04.55 is specifically for acquired stenosis of nasolacrimal duct. Related codes cover Dacryolith (H04.51), Eversion of lacrimal punctum (H04.52), neonatal obstruction of nasolacrimal duct (H04.53), stenosis of lacrimal canaliculi (H04.54), stenosis of lacrimal punctum (H04.56) and stenosis of lacrimal sac (H04.57).
To report this condition, pick the subcode that matches the documentation: H04.551 (duct), H04.552 (duct), H04.553 (duct) and H04.559 (duct).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
