chapter 2: Neoplasms
22 billable codes under D3A: none are a CC or MCC; all map to HCC 22 (Bladder, Colorectal, and Other Cancers).An HCC counts toward a Medicare Advantage patient's risk score.

Instructional notes
Excludes2: not included here, code separately if applicable
- benign pancreatic islet cell tumors (D13.7)
Code also: add a code for this too, order depends on the encounter
- any associated multiple endocrine neoplasia [MEN] syndromes (E31.2-)
Use additional code: add a second code for this, listed after this one

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)

About the condition

Benign Tumors
Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.
