H16 — Keratitis
Not billable
Is H16 billable?
No — H16 is a non-billable header code. H16 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 60 billable codes beneath H16.

What codes fall under H16? (7)
How long has H16 existed?
H16 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
