ICD-10-CM Code S22.5XXB
Flail chest, initial encounter for open fracture
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.S22.5XXB is a billable ICD code used to specify a diagnosis of flail chest, initial encounter for open fracture. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code S225 is used to code Flail chest
Flail chest is a life-threatening medical condition that occurs when a segment of the rib cage breaks under extreme stress and becomes detached from the rest of the chest wall. It occurs when multiple adjacent ribs are broken in multiple places, separating a segment, so a part of the chest wall moves independently. The number of ribs that must be broken varies by differing definitions: some sources say at least two adjacent ribs are broken in at least two places, some require three or more ribs in two or more places. The flail segment moves in the opposite direction as the rest of the chest wall: because of the ambient pressure in comparison to the pressure inside the lungs, it goes in while the rest of the chest is moving out, and vice versa. This so-called "paradoxical breathing" can increase the work and pain involved in breathing. Studies have found that up to half of people with flail chest die.
