The ICD code D485 is used to code Dysplastic nevus A dysplastic nevus or atypical mole is a nevus (mole) whose appearance is different from that of common moles. In 1992, the NIH recommended that the term "dysplastic nevus" be avoided in favor of the term "atypical mole".
Why ICD-10 codes are important
The ICD-10-CM is a catalog of diagnosis codes used by medical professionals for medical coding and reporting in health care settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates.
Melanocytic nevi are benign neoplasms or hamartomas composed of melanocytes, the pigment-producing cells that constitutively colonize the epidermis. Melanocytes are derived from the neural crest and migrate during embryogenesis to selected ectodermal sites (primarily the skin and the CNS), but also to the eyes and the ears.
Intradermal melanocytic nevi are common, benign, pigmented skin tumors formed by proliferation of dermal melanocytes. A number of notable, uncommon changes may be observed in intradermal melanocytic nevi. In particular, their association with lymphatic invasion is an extremely rare phenomenon.

It is a benign skin growth and are caused by the sun, immune status or genetic factors. For example: People with many moles tend to have family members that also have many moles, and their moles may have a similar appearance. New moles may erupt following the use of BRAF inhibitor drugs (vemurafenib, dabrafenib).
Atypical nevi, also known as dysplastic nevi, are benign acquired melanocytic neoplasms. Atypical nevi share some of the clinical features of melanoma, such as asymmetry, irregular borders, multiple colors, and diameter >5 mm (picture 1A). They occur sporadically or in a familial setting.
A abnormal, congenital formation or mark on the skin or neighboring mucosa that does not show neoplastic growth. [
(dis-PLAS-tik NEE-vus) A specific type of nevus (mole) that looks different from a common mole. Dysplastic nevi are mostly flat and often larger than common moles and have borders that are irregular. A dysplastic nevus can contain different colors, which can range from pink to dark brown.
An acral nevus is a cutaneous condition of the palms, soles, fingers, or toes (peripheral body parts), characterized by a skin lesion that is usually macular or only slightly elevated, and may display a uniform brown or dark brown color, often with linear striations.

Cases of malignant melanoma arising from an intradermal nevus have rarely been reported. Moreover, previously reported cases showed melanoma cells beneath the intradermal nevus.
Intradermal Nevi Another name for these moles is “dermal nevi.” The melanocytes that make up an intradermal nevus are located in the dermis (below the dermo-epidermal junction).
There are 4 common types of moles: congenital moles, dysplastic nevi, acquired nevi, and spitz nevi. Below are the differences between each.
A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere.
The 2022 edition of ICD-10-CM D22.5 became effective on October 1, 2021.
All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm. Morphology [Histology] Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, ...
The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes. Primary malignant neoplasms overlapping site boundaries.

Nevus (or naevus, plural nevi or naevi, from nævus, Latin for "birthmark") is the medical term for sharply-circumscribed [1] and chronic lesions of the skin. These lesions are commonly named birthmarks and moles. Nevi are benign by definition.
Nevi are benign by definition. Using the term nevus and nevi loosely, most physicians and dermatologists are actually referring to a variant of nevus called the "Melanocytic nevus", which are composed of melanocytes.
