AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2023 Issue 4; New/Revised ICD-10-CM Codes
Familial Adenomatous Polyposis and Benign Neoplasm of Ill-Defined Sites of Digestive System
Code D13.9, Benign neoplasm of ill-defined sites within the digestive system, was expanded to create codes D13.91, Familial adenomatous polyposis, and D13.99, Benign neoplasm of ill-defined sites within the digestive system.Familial adenomatous polyposis (FAP) is a rare inherited cancer predisposition syndrome characterized by hundreds to thousands of precancerous colorectal polyps (adenomatous polyps). There are three types of FAP: classic, attenuated, and autosomal recessive. The classic and attenuated types are caused by mutations in the adenomatous polyposis coli (APC) gene. The autosomal recessive type is caused by mutations in the MUTYH gene, which is also known...

Article Overview
This article covers an ICD-10-CM update affecting familial adenomatous polyposis and benign neoplasm coding for ill-defined digestive system sites. It provides background on familial adenomatous polyposis, including its major hereditary subtypes, associated genes, and general clinical features. The article is relevant for coders, clinical documentation specialists, and providers who need to understand how the expanded diagnosis classification relates to hereditary colorectal cancer risk and digestive system neoplasm reporting.
Why This Topic Matters
Accurate diagnosis coding for hereditary polyposis conditions affects problem lists, claims, risk adjustment, and communication among clinicians, coders, and payers. Understanding the scope of the updated classification helps users distinguish the expanded family of digestive system neoplasm codes from the broader hereditary syndrome discussed in the article.
