D229 - A mole (melanocytic nevus) that has not been identified as being in a specific location on the body.
International Classification of Diseases
What is a ICD-10 Code?
ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.
Detailed Description
This code refers to a melanocytic nevus — commonly known as a mole — where the specific location on the body has not been documented or specified. Moles are very common, benign (non-cancerous) skin growths made up of pigment-producing cells called melanocytes. They can appear anywhere on the body, vary in color from pink to dark brown, and may be flat or raised. Most moles are harmless, but they are sometimes examined or removed to rule out skin cancer, particularly melanoma. This diagnosis was recorded during a new patient office visit, meaning this was likely the first time you were seen by this provider for evaluation of the mole.
Additional Information
A diagnosis of D22.9 (Melanocytic nevi, unspecified) simply means a mole was identified but its exact body location was not specified in the medical record. This is a very common and typically benign finding. However, any mole should be monitored using the ABCDE rule: Asymmetry, Border irregularity, Color variation, Diameter larger than a pencil eraser, and Evolving changes. If any of these warning signs are present, consult your healthcare provider promptly. This code does not indicate cancer.

What's Required Before This
- New patient office visit (first-time visit with this provider)
- Visual or physical examination of the skin lesion
- Patient medical history review
What to Expect After
- Regular skin self-examinations to monitor moles for changes in size, shape, or color
- Annual or periodic dermatology check-ups, especially if you have many moles or a family history of skin cancer
- Follow up with your provider if the mole changes appearance, bleeds, itches, or becomes painful
- Possible biopsy or removal if the mole shows suspicious characteristics
- Sun protection measures (sunscreen, protective clothing) to reduce skin cancer risk
