What This Code Means

H30.121 is the ICD-10-CM diagnosis code for disseminated chorioretinal inflammation, peripheral right eye. Inflammation affecting the choroid and retina spread across the outer edges (peripheral areas) of the right eye. H30.121 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of choroid and retina (h30-h36).

H30.121 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Distinguish between peripheral (outer edges) and posterior pole (central back) locations as they use different code families.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H30.121 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Distinguish between peripheral (outer edges) and posterior pole (central back) locations as they use different code families
  • Ensure documentation clearly indicates right eye involvement and peripheral location
