D22.22
BillableMelanocytic nevi of left ear and external auricular canal
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
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.
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
