ICD-10-CM Code for Moles on Face
The ICD-10-CM code for a benign melanocytic nevus (mole) on the face is D22.39 (Other benign neoplasm of skin of other parts of face).
Coding Structure for Facial Nevi
The ICD-10-CM uses the D22 series for benign melanocytic nevi, with anatomic site-specific subcodes:
- D22.3 covers benign neoplasms of skin of other and unspecified parts of face
- D22.30: Benign neoplasm of skin of unspecified part of face
- D22.39: Benign neoplasm of skin of other parts of face (most commonly used for facial moles)
For more specific facial locations, alternative codes include:
- D22.31: Benign neoplasm of skin of nose
- D22.32: Benign neoplasm of skin of right ear and external auricular canal
- D22.33: Benign neoplasm of skin of left ear and external auricular canal
Clinical Context
While the provided evidence focuses primarily on clinical management and classification of melanocytic nevi rather than coding 1, 2, the coding question is straightforward. The D22.39 code applies to:
- Acquired melanocytic nevi (common moles that develop after birth) 2
- Small to medium congenital melanocytic nevi on the face (though larger congenital nevi may warrant additional documentation) 1
- Benign intradermal, junctional, or compound nevi 2, 3
Important Coding Considerations
Use D22.39 only when the nevus is confirmed or clinically assessed as benign. If there are atypical features, dysplastic changes, or concern for malignancy, different codes apply (such as D48.5 for neoplasm of uncertain behavior).
The code does not distinguish between:
- Congenital versus acquired nevi
- Junctional, compound, or intradermal subtypes
- Size of the lesion
These clinical details should be documented in the medical record but do not change the primary diagnosis code for a benign facial nevus.
