Neoplasm of uncertain behavior of appendix
Valid for Submission
| ICD-10: | D37.3 |
| Short Description: | Neoplasm of uncertain behavior of appendix |
| Long Description: | Neoplasm of uncertain behavior of appendix |
Code Classification
D37.3 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of appendix. The code D37.3 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 D37.3 might also be used to specify conditions or terms like carcinoid tumor of appendix, neoplasm of uncertain behavior of appendix or neuroendocrine neoplasm of appendix.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: appendix or intestine, intestinal large appendix .
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Carcinoid tumor of appendix
- Neoplasm of uncertain behavior of appendix
- Neuroendocrine neoplasm of appendix
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code D37.3 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 D37.3 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D37.3 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 D37.3 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
Colonic Diseases
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.
