You Be the Coder: History of Cancer Diagnosis

Why This Topic Matters

Accurate diagnosis coding affects whether a case is treated as active cancer or as a past history of cancer, which can change how surveillance and follow-up encounters are represented in claims and records. This is especially important for post-resection colorectal cancer cases and related oncology follow-up.

2. Answer

   Explains the broad principles discussed in the article for moving from an active cancer diagnosis to a history code after treatment. Includes discussion of follow-up encounters, registry timing, and post-treatment assessment contexts.

3. Example scenario and diagnosis selection

   Uses a colorectal resection and subsequent endoscopic surveillance scenario to illustrate the type of diagnosis categories referenced. Also notes the article’s discussion of a situation involving continued oncology-related findings after surgery and subsequent treatment.
