Code Classification

  • Neoplasms
    (C00–D49)
    • Benign neoplasms, except benign neuroendocrine tumors
      (D10-D36)
      • Other benign neoplasms of connective and other soft tissue
        (D21)

D21.10 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of connective and other soft tissue of unspecified upper limb, including shoulder. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference the parent code D21.1 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic aponeurosis palmar ; Neoplasm, neoplastic connective tissue NEC antecubital fossa or space ; Neoplasm, neoplastic connective tissue NEC arm ; Neoplasm, neoplastic connective tissue NEC elbow ; Neoplasm, neoplastic connective tissue NEC extremity upper ; Neoplasm, neoplastic connective tissue NEC finger ; Neoplasm, neoplastic connective tissue NEC forearm ; etc

Unspecified diagnosis codes like D21.10 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:

  • Benign neoplasm of blood vessel of finger
  • Benign neoplasm of blood vessel of forearm
  • Benign neoplasm of blood vessel of hand
  • Benign neoplasm of blood vessel of shoulder
  • Benign neoplasm of blood vessel of upper arm
  • Benign neoplasm of blood vessel of upper limb
  • Benign neoplasm of muscle of shoulder

  • Benign neoplasm of soft tissue of forearm
  • Benign neoplasm of soft tissue of hand
  • Benign neoplasm of soft tissue of upper arm
  • Benign neoplasm of soft tissues of shoulder
  • Benign neoplasm of soft tissues of upper limb
  • Fibroma of upper limb
  • Neoplasm of blood vessel of finger
  • Neoplasm of blood vessel of forearm
  • Neoplasm of blood vessel of hand
  • Neoplasm of blood vessel of hand
  • Neoplasm of blood vessel of shoulder
  • Neoplasm of blood vessel of upper arm
  • Neoplasm of muscle of shoulder

  • ICD-9-CM Code: 215.2 - Ben neo soft tissue arm
    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 D21.1 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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
