ICD-10-CM Code K56.1

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

K56.1 is a billable ICD code used to specify a diagnosis of intussusception. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code K561 is used to code Intussusception (medical disorder)

An intussusception is a medical condition in which a part of the intestine invaginates (folds into) into another section of intestine, similar to the way the parts of a collapsible telescope retract into one another. This can often result in an obstruction. The part that prolapses into the other is called the intussusceptum, and the part that receives it is called the intussuscepiens. Intussusception is a medical emergency and a patient should be seen immediately to reduce risk.
