What This Code Means
D31.10 is the ICD-10-CM diagnosis code for benign neoplasm of unspecified cornea. A non-cancerous growth on the cornea (the clear front part of the eye), but the specific eye is not documented. D31.10 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D31.10 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.
Query the provider for laterality specification as corneal lesions are typically unilateral.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D31.10 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Query the provider for laterality specification as corneal lesions are typically unilateral
- •Corneal neoplasms are rare; verify the diagnosis is not a scar, dystrophy, or other non-neoplastic condition
