H20 — Iridocyclitis
Not billable
Is H20 billable?
No — H20 is a non-billable header code. H20 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 38 billable codes beneath H20.

What codes fall under H20? (5)
How long has H20 existed?
H20 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
