KC20.1

ICD-11 MMS 2026-01

Umbilical cutis or polyp of newborn

Description

An umbilical cord polyp is a congenital lesion resulting from persistence of the omphalomesenteric duct. It originates from either the omphalomesenteric duct or from urachal remnants. The polyp may contain intestinal mucosa.

Coding note from above levels

Conditions arising in the perinatal period, even though death or morbidity occurs later, should, as far as possible, be coded to chapter 19, which takes precedence over chapters containing codes for diseases by their anatomical site. For children less than 28 days old, assume that a reported condition developed in the perinatal period, unless the duration is stated and the onset was after the first completed week of life.
