Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the D22 range.
Angiofibroma
A benign neoplasm of fibrous tissue in which there are numerous small and large, frequently dilated, vascular channels. (Stedman, 25th ed)
Lumbosacral Region
Region of the back including the LUMBAR VERTEBRAE, SACRUM, and nearby structures.
Mongolian Spot
A bluish-gray to gray-brown benign, melanocytic nevus found usually in the LUMBOSACRAL REGION of dark-skinned people, especially those of East Asian ancestry. It is usually congenital or appears shortly after birth, and disappears in childhood.
About the D22 Code Range
ICD-10 code D22 and its subcategories are used to identify and document melanocytic nevi, commonly known as moles. These benign skin growths can appear on various body parts including the lip, eyelids, ear, face, scalp, neck, trunk, and limbs. Each code from D22.0 to D22.9 specifies the exact location of the nevus, facilitating precise medical coding and treatment planning.
These codes cover a range of melanocytic nevi types, including congenital and acquired forms, and variants such as junctional or compound nevi. For example, D22.0 addresses nevi of the lip, also referred to as “benign neoplasm of skin of lip,” and D22.10 specifies nevi on the eyelid or canthus, also known by synonyms like “pigmented hairy epidermal nevus of upper eyelid.” Similarly, codes like D22.21 and D22.39 cover nevi on the right ear and various parts of the face, respectively. The broad code D22.9 captures unspecified or atypical melanocytic nevi, which may include descriptions like “junctional melanocytic nevus” or “dysplastic nevus.” These codes are essential for accurately classifying these common benign skin lesions in medical records and claims.
