2022 ICD-10-CM Code D12.4

Benign neoplasm of descending colon

Version 2021

Valid for Submission

ICD-10:D12.4
Short Description:Benign neoplasm of descending colon
Long Description:Benign neoplasm of descending colon

Code Classification

  • Neoplasms (C00–D48)
    • Benign neoplasms, except benign neuroendocrine tumors (D10-D36)
      • Benign neoplasm of colon, rectum, anus and anal canal (D12)

D12.4 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of descending colon. The code D12.4 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code D12.4 might also be used to specify conditions or terms like adenoma of descending colon, benign neoplasm of descending colon or polyp of descending colon.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: intestine, intestinal large colon descending or intestine, intestinal large colon distal or intestine, intestinal large colon left .

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code D12.4 are found in the index:

Approximate Synonyms

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

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D12.4 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The code D12.4 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

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.

Colonic Polyps

A polyp is an extra piece of tissue that grows inside your body. Colonic polyps grow in the large intestine, or colon. Most polyps are not dangerous. However, some polyps may turn into cancer or already be cancer. To be safe, doctors remove polyps and test them. Polyps can be removed when a doctor examines the inside of the large intestine during a colonoscopy.

Anyone can get polyps, but certain people are more likely than others. You may have a greater chance of getting polyps if you

Most colon polyps do not cause symptoms. If you have symptoms, they may include blood on your underwear or on toilet paper after a bowel movement, blood in your stool, or constipation or diarrhea lasting more than a week.
