What This Code Means
H47.521 is the ICD-10-CM diagnosis code for disorders of visual pathways in (due to) neoplasm, right side. Problems with the visual pathways on the right side of the brain caused by a tumor or abnormal growth. H47.521 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of optic nerve and visual pathways (h46-h47).
H47.521 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.
Confirm the neoplasm is documented and laterality is right; code the neoplasm separately with appropriate ICD-10 code.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H47.521 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Confirm the neoplasm is documented and laterality is right; code the neoplasm separately with appropriate ICD-10 code
- •If laterality is unspecified, use H47.529 instead
