H16.26 — Vernal keratoconjunctivitis, with limbar and corneal involvement
H16.26 is a non-billable header ICD-10-CM code for vernal keratoconjunctivitis, with limbar and corneal involvement. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- vernal conjunctivitis without limbar and corneal involvement (H10.44)
Other codes that can never be billed with H16.26
These codes carry an Excludes1 note pointing at H16.26. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H16.26 alone.
- H10.44Vernal conjunctivitis
Risk adjustment
H16.26 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
