ICD-10-CM Code D21.0

Benign neoplasm of connective and other soft tissue of head, face and neck

Version 2021 Billable Code Neoplasm Benign

Valid for Submission

D21.0 is a billable code used to specify a medical diagnosis of benign neoplasm of connective and other soft tissue of head, face and neck. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code D21.0 might also be used to specify conditions or terms like apocrine cystadenoma, apocrine hidrocystoma of eyelid, benign neoplasm of blood vessel of face, benign neoplasm of blood vessel of head, benign neoplasm of blood vessel of neck, benign neoplasm of cervical vertebral column, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic carotid (artery) ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] auricular ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] ear (external) ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] eyelid ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] pinna ; Neoplasm, neoplastic connective tissue NEC auricle (ear) ; Neoplasm, neoplastic connective tissue NEC cervical region ; etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code D21.0:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Benign neoplasm of connective tissue of ear
  • Benign neoplasm of connective tissue of eyelid

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • benign neoplasm of connective tissue of orbit D31.6

Table of Neoplasms

The code D21.0 is included 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.

Information for Patients


Benign Tumors

Also called: Benign neoplasms, Noncancerous 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.
