C16: ICD10 Code for Malignant neoplasm of stomach

C16 refers to Malignant neoplasm of stomach, a type of gastrointestinal cancer affecting various parts of the digestive system. These malignancies can cause symptoms like bleeding, pain, or obstruction and may require surgery, chemotherapy, or radiation therapy. Accurate ICD10 coding ensures appropriate care planning, oncology tracking, and reimbursement.

Symptoms

• Abdominal pain – Common in cancers of the digestive organs
• Weight loss – Often unexplained and progressive
• Blood in stool or vomit – Seen in GI tract cancers
• Changes in bowel habits – Diarrhea, constipation, or pencil-thin stool
• Jaundice – Indicative of liver, bile duct, or pancreatic cancers
• Nausea or vomiting – Especially in upper GI malignancies
• Fatigue – From chronic blood loss or systemic effects of cancer

Diagnosis

Diagnosis of Malignant neoplasm of stomach involves imaging (CT, MRI, endoscopy), blood tests (e.g., liver function, tumor markers), and biopsy. Colonoscopy is crucial for colorectal cancers, while endoscopy is used for upper GI cancers. Histopathological confirmation and staging are essential for treatment planning and prognosis estimation.

ICD10 Code Usage

ICD10 code C16 is used in oncology records, pathology reports, billing systems, and national cancer registries. It supports treatment authorization, outcome tracking, clinical research, and public health planning for gastrointestinal cancers.
