ICD-10-CM Code D01.2

Carcinoma in situ of rectum

Version 2021 Billable Code Neoplasm CaInSitu

Valid for Submission

D01.2 is a billable code used to specify a medical diagnosis of carcinoma in situ of rectum. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code D01.2 might also be used to specify conditions or terms like carcinoma in situ of colon, carcinoma in situ of rectosigmoid junction, carcinoma in situ of rectum, carcinoma in situ of rectum, carcinoma in situ of rectum and rectosigmoid junction, carcinoma in situ of sigmoid colon, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic rectum (ampulla) .

Diagnostic Related Groups

The ICD-10 code D01.2 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).

Table of Neoplasms

The code D01.2 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


Colorectal Cancer

Also called: Colon cancer, Rectal cancer

The colon and rectum are part of the large intestine. Colorectal cancer occurs when tumors form in the lining of the large intestine. It is common in both men and women. The risk of developing colorectal cancer rises after age 50. You're also more likely to get it if you have colorectal polyps, a family history of colorectal cancer, ulcerative colitis or Crohn's disease, eat a diet high in fat, or smoke.

Symptoms of colorectal cancer include

  • Diarrhea or constipation
  • A feeling that your bowel does not empty completely
  • Blood (either bright red or very dark) in your stool
  • Stools that are narrower than usual
  • Frequent gas pains or cramps, or feeling full or bloated
  • Weight loss with no known reason
  • Fatigue
  • Nausea or vomiting

Because you may not have symptoms at first, it's important to have screening tests. Everyone over 50 should get screened. Tests include colonoscopy and tests for blood in the stool. Treatments for colorectal cancer include surgery, chemotherapy, radiation, or a combination. Surgery can usually cure it when it is found early.
