D23.20 - Other benign neoplasm of skin of unspecified ear and external auricular canal

Version 2023
ICD-10:D23.20
Short Description:Oth benign neoplasm skin/ unsp ear and external auric canal
Long Description:Other benign neoplasm of skin of unspecified ear and external auricular canal
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Benign neoplasms, except benign neuroendocrine tumors (D10-D36)
      • Other benign neoplasms of skin (D23)

D23.20 is a billable ICD-10 code used to specify a medical diagnosis of other benign neoplasm of skin of unspecified ear and external auricular canal. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms reference the parent code D23.2 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic auditory ; Neoplasm, neoplastic auditory canal (external) (skin) ; Neoplasm, neoplastic auricle, ear [See Also: Neoplasm, skin, ear] ; Neoplasm, neoplastic auricular canal (external) [See Also: Neoplasm, skin, ear] ; Neoplasm, neoplastic canal auditory (external) [See Also: Neoplasm, skin, ear] ; Neoplasm, neoplastic canal auricular (external) [See Also: Neoplasm, skin, ear] ; Neoplasm, neoplastic concha [See Also: Neoplasm, skin, ear] ; etc

Unspecified diagnosis codes like D23.20 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The parent code D23.2 of the current diagnosis code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education


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.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

Skin Conditions

Your skin is your body's largest organ. It covers and protects your body. Your skin:

Anything that irritates, clogs, or inflames your skin can cause symptoms such as redness, swelling, burning, and itching. Allergies, irritants, your genetic makeup, and certain diseases and immune system problems can cause rashes, hives, and other skin conditions. Many skin problems, such as acne, also affect your appearance.
