2021 ICD-10-CM Code C25.9
Malignant neoplasm of pancreas, unspecified
Valid for Submission
C25.9 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of pancreas, unspecified. The code C25.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code C25.9 might also be used to specify conditions or terms like acinar cell carcinoma of pancreas, adenocarcinoma of pancreas, carcinoma of pancreas, cystadenocarcinoma of pancreas, exocrine pancreas tnm finding , exocrine pancreas tnm finding, etc.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic pancreas .
Unspecified diagnosis codes like C25.9 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.

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code C25.9 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). applicable from 10/01/2020 through 09/30/2021.

Table of Neoplasms
The code C25.9 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
Pancreatic Cancer
The pancreas is a gland behind your stomach and in front of your spine. It produces the juices that help break down food and the hormones that help control blood sugar levels. Pancreatic cancer usually begins in the cells that produce the juices. Some risk factors for developing pancreatic cancer include
- Smoking
- Long-term diabetes
- Chronic pancreatitis
- Certain hereditary disorders
Pancreatic cancer is hard to catch early. It doesn't cause symptoms right away. When you do get symptoms, they are often vague or you may not notice them. They include yellowing of the skin and eyes, pain in the abdomen and back, weight loss and fatigue. Also, because the pancreas is hidden behind other organs, health care providers cannot see or feel the tumors during routine exams. Doctors use a physical exam, blood tests, imaging tests, and a biopsy to diagnose it.
Because it is often found late and it spreads quickly, pancreatic cancer can be hard to treat. Possible treatments include surgery, radiation, chemotherapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.
