2025 ICD-10-CM code D22

Melanocytic nevi. Includes: atypical nevus, blue nevus, hairy pigmented nevus, and nevus NOS.

The ICD-10-CM code D22 is used for all melanocytic nevi, including atypical, blue, and hairy nevi. Chapter 4 codes can be used to identify any associated functional activity. If a malignant transformation occurs, the appropriate code for melanoma should be used.

Medical necessity for treatment is typically based on changes in the nevus that raise concern for malignancy, such as rapid growth, change in color or shape, bleeding, or itching. Cosmetic removal can also be considered.

Diagnosis is typically based on patient history, signs and symptoms, and a physical examination. A complete excisional biopsy might be performed to determine if the lesion is benign or malignant. Imaging studies, like MRI, may be considered for individuals with multiple congenital nevi over the spine.

In simple words: A melanocytic nevus, commonly known as a mole, is a non-cancerous skin growth made up of melanocytes, the cells that give skin its color. Moles can be flat or raised, and their color can range from light tan to dark brown or even blue. They can be present at birth or appear later in life.While most moles are harmless, it's important to monitor them for changes, as some can develop into skin cancer.

Melanocytic nevi are benign (non-cancerous) lesions characterized by an overgrowth of melanocytes, cells that produce melanin, the pigment responsible for skin and hair color. These lesions, often referred to as moles, can vary in appearance, from flat to raised, and in color, from tan to brown or even black or blue.They can be present at birth (congenital) or develop later in life (acquired). Variants include blue nevi, Spitz nevi, and Clark nevi (also known as dysplastic or atypical nevi). While benign, melanocytic nevi, especially congenital ones, can develop into melanoma, a type of skin cancer.

Example 1: A 25-year-old patient presents with a new, rapidly growing mole on their back. After examination and biopsy, it is determined to be a benign melanocytic nevus (D22)., A newborn infant is noted to have a large congenital melanocytic nevus on their leg (D22). The parents are counseled about monitoring the lesion for changes., A 40-year-old patient has multiple atypical nevi (D22) and a family history of melanoma. They undergo regular skin checks to monitor for any changes in their moles.

Documentation should include the location, size, color, shape, and any changes observed in the nevus. Biopsy results, if performed, should also be documented.
