What This Code Means
D22.22 is the ICD-10-CM diagnosis code for melanocytic nevi of left ear and external auricular canal. This code describes benign brown or black moles (melanocytic nevi) located on the left ear or in the ear canal. These are common, non-cancerous skin growths that typically do not require treatment unless they change in appearance or cause irritation. D22.22 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D22.22 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, 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.
Ensure laterality is documented as left ear; if bilateral nevi are present, code both sides separately using D22.21 for right ear and D22.22 for left ear.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D22.22 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure laterality is documented as left ear; if bilateral nevi are present, code both sides separately using D22.21 for right ear and D22.22 for left ear
- •Distinguish between melanocytic nevi (benign moles) and melanoma; confirm the pathology report documents 'nevus' rather than malignant melanoma before assigning this code
