H10.44 — Vernal conjunctivitis

Billable / specific codeICD-10-CM

H10.44 is a billable, specific ICD-10-CM code for vernal conjunctivitis. It is valid for submission on a claim.

Excludes1 — never code together

Other codes that can never be billed with H10.44

These codes carry an Excludes1 note pointing at H10.44. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H10.44 alone.

Risk adjustment

H10.44 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.

Medicare coverage

H10.44 is named in 12 Medicare coverage policies — 12 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
