D22 is a non-billable ICD-10-CM category code for melanocytic nevi, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D22.0, D22.10, D22.111, and D22.112.

Specific Coding for Melanocytic neviOverview

  • Use D22.0 for Melanocytic nevi of lip

  • D22.1 for Melanocytic nevi of eyelid, including canthus

  • Use D22.10 for Melanocytic nevi of unspecified eyelid, including canthus

  • D22.11 for Melanocytic nevi of right eyelid, including canthus

  • D22.12 for Melanocytic nevi of left eyelid, including canthus

  • D22.2 for Melanocytic nevi of ear and external auricular canal

  • Use D22.20 for Melanocytic nevi of unspecified ear and external auricular canal

  • Use D22.21 for Melanocytic nevi of right ear and external auricular canal

  • Use D22.22 for Melanocytic nevi of left ear and external auricular canal

  • D22.3 for Melanocytic nevi of other and unspecified parts of face

  • Use D22.30 for Melanocytic nevi of unspecified part of face

  • Use D22.39 for Melanocytic nevi of other parts of face

  • Use D22.4 for Melanocytic nevi of scalp and neck

  • Use D22.5 for Melanocytic nevi of trunk

  • D22.6 for Melanocytic nevi of upper limb, including shoulder

  • Use D22.60 for Melanocytic nevi of unspecified upper limb, including shoulder

  • Use D22.61 for Melanocytic nevi of right upper limb, including shoulder

  • Use D22.62 for Melanocytic nevi of left upper limb, including shoulder

  • D22.7 for Melanocytic nevi of lower limb, including hip

  • Use D22.70 for Melanocytic nevi of unspecified lower limb, including hip

  • Use D22.71 for Melanocytic nevi of right lower limb, including hip

  • Use D22.72 for Melanocytic nevi of left lower limb, including hip

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D22: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

  • atypical nevus
  • blue hairy pigmented nevus
  • nevus NOS

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • 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).

Clinical InformationClinical

  • Nevus, Pigmented

    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.

Patient EducationClinical

Birthmarks

Birthmarks are abnormalities of the skin that are present when a baby is born. There are two types of birthmarks. Vascular birthmarks are made up of blood vessels that haven't formed correctly. They are usually red. Two types of vascular birthmarks are hemangiomas and port-wine stains.
