Contusion of diaphragm, initial encounter

This code signifies a bruise or minor injury to the diaphragm, the muscle separating the chest and abdomen, without an open wound. It indicates damage to the diaphragm's tissues, typically caused by blunt force trauma, leading to swelling and pain.

Apply this code when documenting an initial presentation of a patient who has sustained a blunt injury to the torso, and diagnostic imaging or clinical assessment confirms a contusion of the diaphragm. This is appropriate for cases such as motor vehicle accidents, falls, or direct blows to the chest or upper abdomen.

• Ensure documentation clearly specifies a contusion and not a laceration or rupture of the diaphragm.
• Verify that this is the initial encounter for the injury; subsequent encounters will require a different seventh character.
• Always code any associated external cause of injury (e.g., V-code for MVA) and other co-occurring injuries.
