Family history of adenomatous and serrated polyps

This code indicates a patient's family history of precancerous growths in the colon or rectum, specifically adenomatous polyps (e.g., tubular, tubulovillous, villous adenomas) and serrated polyps (e.g., sessile serrated lesions, traditional serrated adenomas). These types of polyps are known to have malignant potential and increase the risk of colorectal cancer.

Use this code when documenting a patient's family history of these specific polyp types, which may necessitate increased surveillance or screening. This is particularly relevant for patients undergoing colonoscopy or other colorectal cancer screening procedures.

• Do not use this code for a personal history of polyps; use codes from category Z86.01.
• Ensure documentation specifies "adenomatous" or "serrated" polyps in the family history.
• This code is often used as a secondary diagnosis to support medical necessity for screening or surveillance.
