What ICD-10 codes are used for moles?

If you're looking for mole ICD codes, please note that there are no ICD-10 codes that mention mole in their names. Instead, they go by the medical term for mole, melanocytic nevus.

The basic ICD-10 code for mole you're looking for is D22.9 - Melanocytic nevi, unspecified. It's meant to be used only when your patient has moles, but you haven't specified the locations.

Once you've identified the specific locations of the moles, you must use more specific ICD-10 codes based on their locations. Here are examples of specific codes:

  • D22.0 - Melanocytic nevi of lip
  • D22.10 - Melanocytic nevi of unspecified eyelid, including canthus
  • D22.20 - Melanocytic nevi of unspecified ear and external auricular canal
  • D22.30 - Melanocytic nevi of unspecified part of face
  • D22.60 - Melanocytic nevi of unspecified upper limb, including shoulder
  • D22.70 - Melanocytic nevi of unspecified lower limb, including hip

For Items 2 to 5, the specific part isn't specified. Once you've identified the specific parts, you must use specific variants of their ICD-10 codes (e.g., right eyelid, left eyelid, right upper eyelid, left upper eyelid, left ear, right ear, left upper limb, right upper limb, etc.).

Which mole ICD-10 codes are billable?

All of the aforementioned codes are billable.

Clinical information

  • Melanocytic nevi, commonly called moles, are common dark growths on the skin. These growths appear as spots or lumps with varying sizes and textures. They are usually colored brown or black.
  • Moles are made up of melanocytes. These are pigmented cells that produce melanin. When these are exposed to sunlight, they boost their melanin production. Light-skinned people become tan, while dark-skinned people become darker.
  • Moles are mostly harmless or considered benign neoplasms, so they can just be left alone. However, if a mole changes, like changes in color, symmetry, shape, size, and borders, it's best to see a healthcare professional to check for the possibility of Melanoma, a type of skin cancer.

Synonyms include

Commonly asked questions

Dysplastic moles, sometimes called atypical moles, don’t look like typical moles. They have irregular shapes and uneven colors. They can also be larger than regular moles. They look like smudges on the skin.

Most of them aren’t. However, dysplastic moles have a chance of becoming cancerous.

If they are cancerous, they can and should be removed before they get any worse. However, some people have their moles removed for cosmetic reasons.
