60.3 - Determining High Risk for Developing Colorectal Cancer
(Rev. 13025, Issued: 12-23-24; Effective: 10-01-24; Implementation: 03-20-25)
A. Characteristics of the High-Risk Individual
An individual at high risk for developing colorectal cancer has one or more of the following:
•
A close relative (sibling, parent, or child) who has had colorectal cancer or an adenomatous
polyp.
•
A family history of familial adenomatous polyposis.
•
A family history of hereditary nonpolyposis colorectal cancer.
•
A personal history of adenomatous polyps.
•
A personal history of colorectal cancer; or
•
Inflammatory bowel disease, including Crohn’s Disease, and ulcerative colitis.
B. Partial List of ICD-10-CM Codes Indicating High Risk
Listed below are some examples of diagnoses that meet the high-risk criteria for colorectal cancer.
This is not an all-inclusive list. There may be more instances of conditions, which may be coded
and could be considered high risk at the medical directors’ discretion.
