2022 ICD-10-CM Code D01.49
Carcinoma in situ of other parts of intestine
Code Classification
D01.49 is a billable diagnosis code used to specify a medical diagnosis of carcinoma in situ of other parts of intestine. The code D01.49 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 D01.49 might also be used to specify conditions or terms like carcinoma in situ of duodenum, carcinoma in situ of ileum, carcinoma in situ of jejunum, carcinoma in situ of meckel's diverticulum, carcinoma in situ of small intestine , carcinoma in situ of small intestine, etc.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: duodenojejunal junction ; duodenum ; ileum ; intestine, intestinal small duodenum ; intestine, intestinal small ileum ; intestine, intestinal small jejunum ; jejunum ; etc
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Carcinoma in situ of duodenum
- Carcinoma in situ of ileum
- Carcinoma in situ of jejunum
- Carcinoma in situ of Meckel's diverticulum
- Carcinoma in situ of small intestine
- Carcinoma in situ of small intestine
- Carcinoma in situ of small intestine
- Neoplasm of Meckel's diverticulum
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code D01.49 is grouped in the following groups for version MS-DRG V39.0 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). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 374 | DIGESTIVE MALIGNANCY WITH MCC | 06 | 2.0679 |
| 375 | DIGESTIVE MALIGNANCY WITH CC | 06 | 1.2049 |
| 376 | DIGESTIVE MALIGNANCY WITHOUT CC/MCC | 06 | 0.8952 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert D01.49 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D01.49 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 D01.49 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.

Information for Patients
Colorectal 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.

Intestinal Cancer
Your small intestine is part of your digestive system. It is a long tube that connects your stomach to your large intestine. Intestinal cancer is rare, but eating a high-fat diet or having Crohn's disease, celiac disease, or a history of colonic polyps can increase your risk.
Possible signs of small intestine cancer include
- Abdominal pain
- Weight loss for no reason
- Blood in the stool
- A lump in the abdomen
Imaging tests that create pictures of the small intestine and the area around it can help diagnose intestinal cancer and show whether it has spread.
Surgery is the most common treatment. Additional options include chemotherapy, radiation therapy, or a combination.
