H10 — Conjunctivitis

Not billable

Is H10 billable?

No — H10 is a non-billable header code. H10 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 H10.

Excludes1 — never code together

The conditions below can never be reported together with H10 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

keratoconjunctivitis (H16.2-)

Excludes2 — not included here — inherited from Chapter 7

The conditions below are not part of H10, but a patient may have both at the same time. When documentation supports it, H10 and the excluded code may both be reported.
