Neoplasm Coding at a Glance (ICD-10-CM Cheat Sheet)

A two-page quick reference for coding neoplasms in ICD-10-CM (Chapter 2). It shows how to use the Neoplasm Table and what to sequence first, so you can code cancer encounters with confidence.

WHAT'S INSIDE

• Page 1: finding the code step by step (histology first, then the Table, then the Tabular), the 6 Neoplasm Table columns with their code ranges, uncertain vs. unspecified behavior, "metastatic from" vs. "metastatic to", overlapping sites, lymphoma spread, C80.0 and C80.1, and a decision box for current cancer vs. personal history (Z85) vs. remission
• Page 2: a "what goes first" table by the reason for the encounter (primary or secondary site, chemo, immunotherapy, radiation, anemia of cancer vs. anemia from chemo, dehydration, surgical complications, pathological fracture, cancer pain, pregnancy), which codes have remission choices, the Z codes around cancer, and 5 worked examples

GOOD TO KNOW

• Based on the FY2027 ICD-10-CM code set and Official Guidelines (in effect October 1, 2026 to September 30, 2027). Codes change every October, so check the current year.
• This guide covers ICD-10-CM diagnosis coding only. It has no CPT procedure codes.
• Educational reference, not legal or billing advice. Payers and facilities can add their own rules.
• AAPC doesn't allow extra notes or printouts in exam code books, so this is a study aid and work reference, not an exam aid.
• Not affiliated with or endorsed by CMS, NCHS, AHA, AAPC, or AHIMA.
• Digital items generally can't be returned. If a file is missing, damaged, or different from this listing, email thedenialdesk@gmail.com and I'll help sort it out.
• Drafted with help from AI tools, then reviewed and fact-checked by a certified medical coding professional.
