Melanocytic nevi

    2016 2017 2018 2019 2020 2021 Non-Billable/Non-Specific Code
  • D22 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2021 edition of ICD-10-CM D22 became effective on October 1, 2020.
  • This is the American ICD-10-CM version of D22 - other international versions of ICD-10 D22 may differ.

    Neoplasms

    Note
    • Functional activity
    • 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, etc. 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
    • 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. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
    • Malignant neoplasm of ectopic tissue
    • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).
    Neoplasms
Clinical Information
  • A benign (not cancer) growth on the skin that is formed by a cluster of melanocytes (cells that make a substance called melanin, which gives color to skin and eyes). A mole is usually dark and may be raised from the skin.
  • A circumscribed stable malformation of the skin and occasionally of the oral mucosa, which is not due to external causes and therefore presumed to be of hereditary origin.
  • A neoplasm composed of melanocytes that usually appears as a dark spot on the skin.
  • A nevus characterised by the presence of excessive pigment.
  • A nevus containing melanin. The term is usually restricted to nevocytic nevi (round or oval collections of melanin-containing nevus cells occurring at the dermoepidermal junction of the skin or in the dermis proper) or moles, but may be applied to other pigmented nevi.
  • A type of nevus (mole) that looks different from a common mole. A dysplastic nevus is often larger with borders that are not easy to see. Its color is usually uneven and can range from pink to dark brown. Parts of the mole may be raised above the skin surface. A dysplastic nevus may develop into malignant melanoma (a type of skin cancer).
  • Circumscribed stable malformation of the skin and occasionally of the oral mucosa, which is not due to external causes.
  • Moles are growths on the skin. They happen when cells in the skin, called melanocytes, grow in a cluster with tissue surrounding them. Moles are very common. Most people have between 10 and 40 moles. A person may develop new moles from time to time, usually until about age 40.moles are usually pink, tan or brown. They can be flat or raised. They are usually round or oval and no larger than a pencil eraser.about one out of every ten people has at least one unusual (or atypical) mole that looks different from an ordinary mole. The medical term for these unusual moles is dysplastic nevi. They may be more likely than ordinary moles to develop into melanoma, a type of skin cancer. Because of this, you should have a healthcare professional check your moles if they look unusual, grow larger, change in color or outline, or in any other way. nih: national cancer institute
  • Nevus containing melanin; usually restricted to nevocytic nevi (round or oval collections of melanin-containing nevus cells occurring at the dermoepidermal junction of the skin or in the dermis proper) or moles, but may be applied to other pigmented nevi.
  • Solitary or multiple, slightly raised, pigmented lesions with irregular borders, usually measuring more than 0.6cm in greatest dimension. Morphologically, there is melanocytic atypia and the differential diagnosis from melanoma may be difficult. Patients are at an increased risk for the development of melanoma.
