Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
Rules for coding benign and malignant neoplasms: using the Neoplasm Table, sequencing primary and secondary sites, treatment encounters, complications, and current cancer versus personal history.
- Admission/Encounter for treatment of primary site (page 33)
- Admission/Encounter for treatment of secondary site (page 33)
- Coding and sequencing of complications (page 34)
- Primary malignancy previously excised (page 34)
- Admissions/Encounters involving antineoplastic chemotherapy, immunotherapy and radiation therapy (page 35)
- Admission/encounter to determine extent of malignancy (page 36)
- Symptoms, signs, and abnormal findings listed in Chapter 18 associated with neoplasms (page 36)
- Admission/encounter for pain control/management (page 36)

Digestive Diseases
When you eat, your body breaks food down to a form it can use to build and nourish cells and provide energy. This process is called digestion. Your digestive system is a series of hollow organs joined in a long, twisting tube. It runs from your mouth to your anus and includes your esophagus, stomach, and small and large intestines. Your liver, gallbladder and pancreas are also involved. They produce juices to help digestion.
