D12.6 is a billable ICD-10 code used to specify a medical diagnosis of benign neoplasm of colon, unspecified. 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 this diagnosis code given the correct histological behavior: Neoplasm, neoplastic intestine, intestinal large or Neoplasm, neoplastic intestine, intestinal large colon .
Unspecified diagnosis codes like D12.6 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Adenoma of large intestine
- Adenomatous polyp of colon
- Attenuated familial adenomatous polyposis
- Benign lymphoid polyposis of intestine
- Benign neoplasm of colon
- Benign neoplasm of large intestine
- Benign polyp of colon
- Cap polyposis
- Dysplasia of colon
- Dysplasia of large intestine
- Familial adenomatous polyposis due to 5q22.2 microdeletion
- Familial multiple polyposis syndrome
- Gardner syndrome
- Hamartoma of intestine
- Hereditary mixed polyposis syndrome
- Inflammatory polyposis of intestine
- Intestinal polyposis syndrome
- Metaplastic polyposis of intestine

- Villous adenoma of colon
- Gardner Syndrome-. a variant of adenomatous polyposis coli caused by mutation in the apc gene (genes, apc) on chromosome 5. it is characterized by not only the presence of multiple colonic polyposis but also extracolonic adenomatous polyps in the upper gastrointestinal tract; the eye; the skin; the skull; and the facial bones; as well as malignancy in organs other than the gi tract.
- Intestinal Polyposis Syndrome-. a syndrome associated with the development of multiple polyps throughout the intestine. it includes familial adenomatous polyposis , hamartomatous polyposis syndromes, and other rare polyposis syndromes.
- Turcot Syndrome-. an autosomal dominant hereditary neoplastic syndrome caused by mutations in the pms2, mlh1, msh2, or apc genes. there are two types described, type 1, characterized by the presence of glioblastoma and often associated with hereditary nonpolyposis colorectal carcinoma, and type 2, characterized by the presence of medulloblastoma and familiar adenomatous polyposis.
- Turcot Syndrome Type 1-. an autosomal dominant hereditary neoplastic syndrome caused by mutations in the pms2, mlh1, or msh2 genes. it is characterized by the presence of glioblastoma and the absence of familiar adenomatous polyposis. patients often develop hereditary nonpolyposis colorectal carcinoma.
- Turcot Syndrome Type 2-. an autosomal dominant hereditary neoplastic syndrome caused by mutations in the apc gene. it is characterized by the presence of medulloblastoma and familiar adenomatous polyposis.
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 coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Inclusion TermsInclusion 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.
- Adenomatosis of colon
- Benign neoplasm of large intestine NOS
- Polyposis (hereditary) of colon
Type 1 ExcludesType 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.
- inflammatory polyp of colon K51.4
Index to Diseases and Injuries References
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 this diagnosis code are found in the injuries and diseases index:

Table of Neoplasms
This 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.
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.

Your colon, also known as the large intestine, is part of your digestive system. It's a long, hollow tube at the end of your digestive tract where your body makes and stores stool. Many disorders affect the colon's ability to work properly. Some of these include:
- Colorectal cancer
- Colonic polyps - extra tissue growing in the colon that can become cancerous
- Ulcerative colitis - ulcers of the colon and rectum
- Diverticulitis - inflammation or infection of pouches in the colon
- Irritable bowel syndrome - an uncomfortable condition causing abdominal cramping and other symptoms
Treatment for colonic diseases varies greatly depending on the disease and its severity. Treatment may involve diet, medicines and in some cases, surgery.

Juvenile polyposis syndrome
Juvenile polyposis syndrome is a disorder characterized by multiple noncancerous (benign) growths called juvenile polyps. People with juvenile polyposis syndrome typically develop polyps before age 20; however, in the name of this condition "juvenile" refers to the characteristics of the tissues that make up the polyp, not the age of the affected individual. These growths occur in the gastrointestinal tract, typically in the large intestine (colon). The number of polyps varies from only a few to hundreds, even among affected members of the same family. Polyps may cause gastrointestinal bleeding, a shortage of red blood cells (anemia), abdominal pain, and diarrhea. Approximately 15 percent of people with juvenile polyposis syndrome have other abnormalities, such as a twisting of the intestines (intestinal malrotation), heart or brain abnormalities, an opening in the roof of the mouth (cleft palate), extra fingers or toes (polydactyly), and abnormalities of the genitalia or urinary tract.
Juvenile polyposis syndrome is diagnosed when a person has any one of the following: (1) more than five juvenile polyps of the colon or rectum; (2) juvenile polyps in other parts of the gastrointestinal tract; or (3) any number of juvenile polyps and one or more affected family members. Single juvenile polyps are relatively common in children and are not characteristic of juvenile polyposis syndrome.
Three types of juvenile polyposis syndrome have been described, based on the signs and symptoms of the disorder. Juvenile polyposis of infancy is characterized by polyps that occur throughout the gastrointestinal tract during infancy. Juvenile polyposis of infancy is the most severe form of the disorder and is associated with the poorest outcome. Children with this type may develop a condition called protein-losing enteropathy. This condition results in severe diarrhea, failure to gain weight and grow at the expected rate (failure to thrive), and general wasting and weight loss (cachexia). Another type called generalized juvenile polyposis is diagnosed when polyps develop throughout the gastrointestinal tract. In the third type, known as juvenile polyposis coli, affected individuals develop polyps only in their colon. People with generalized juvenile polyposis and juvenile polyposis coli typically develop polyps during childhood.
Most juvenile polyps are benign, but there is a chance that polyps can become cancerous (malignant). It is estimated that people with juvenile polyposis syndrome have a 10 to 50 percent risk of developing a cancer of the gastrointestinal tract. The most common type of cancer seen in people with juvenile polyposis syndrome is colorectal cancer.
