M25.20
Flail joint, unspecified joint
M25.28 M25.20 identifies a flail joint condition at an unspecified anatomical site — a joint that has lost all active and passive motor control due to paralysis, severe ligamentous destruction, or neuromuscular compromise, rendering it abnormally loose and functionally unstable.
Flail joint, other site
A flail joint at a site not covered by any other specific M25.2x subcategory — meaning the joint has lost all functional stability and moves passively beyond its normal range in every plane.
