What This Code Means
D31.90 is the ICD-10-CM diagnosis code for benign neoplasm of unspecified part of unspecified eye. A noncancerous tumor of the eye when the specific part of the eye and which eye are not documented. D31.90 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D31.90 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.
This is the least specific code in the D31 category; use only when no other details are available.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D31.90 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
