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)
