About H44.44

H44.44 is the ICD-10-CM diagnosis code for primary hypotony of eye. It belongs to category H44 (disorders of globe), block H43-H44 (disorders of vitreous body and globe) 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 H44.4 (hypotony of eye), H44.44 is specifically for primary hypotony of eye. Related codes cover unspecified hypotony of eye (H44.40), Flat anterior chamber hypotony of eye (H44.41), due to ocular fistula (H44.42) and due to other ocular disorders (H44.43).

To report this condition, pick the subcode that matches the documentation: H44.441 (eye), H44.442 (eye), H44.443 (bilateral) and H44.449 (eye).

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