D23 is a non-billable ICD-10-CM category code for other benign neoplasms of skin, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D23.0, D23.10, D23.111, and D23.112.

Specific Coding for Other benign neoplasms of skinOverview

Non-specific codes like D23 require more characters. Use one of these billable codes instead:

  • Use D23.0 for Other benign neoplasm of skin of lip

  • D23.1 for Other benign neoplasm of skin of eyelid, including canthus

  • Use D23.10 for Other benign neoplasm of skin of unspecified eyelid, including canthus

  • D23.11 for Other benign neoplasm of skin of right eyelid, including canthus

  • D23.12 for Other benign neoplasm of skin of left eyelid, including canthus

  • D23.2 for Other benign neoplasm of skin of ear and external auricular canal

  • Use D23.20 for Other benign neoplasm of skin of unspecified ear and external auricular canal

  • Use D23.21 for Other benign neoplasm of skin of right ear and external auricular canal

  • Use D23.22 for Other benign neoplasm of skin of left ear and external auricular canal

  • D23.3 for Other benign neoplasm of skin of other and unspecified parts of face

  • Use D23.30 for Other benign neoplasm of skin of unspecified part of face

  • Use D23.39 for Other benign neoplasm of skin of other parts of face

  • Use D23.4 for Other benign neoplasm of skin of scalp and neck

  • Use D23.5 for Other benign neoplasm of skin of trunk

  • D23.6 for Other benign neoplasm of skin of upper limb, including shoulder

  • Use D23.60 for Other benign neoplasm of skin of unspecified upper limb, including shoulder

  • Use D23.61 for Other benign neoplasm of skin of right upper limb, including shoulder

  • Use D23.62 for Other benign neoplasm of skin of left upper limb, including shoulder

  • D23.7 for Other benign neoplasm of skin of lower limb, including hip

  • Use D23.70 for Other benign neoplasm of skin of unspecified lower limb, including hip

  • Use D23.71 for Other benign neoplasm of skin of right lower limb, including hip

  • Use D23.72 for Other benign neoplasm of skin of left lower limb, including hip

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D23: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • benign neoplasm of hair follicles
  • benign neoplasm of sebaceous glands
  • benign neoplasm of sweat glands

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

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).

Patient EducationClinical

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.
