Q: Driver of a motorcycle without a helmet is struck by a large truck on the highway. He arrives with a GCS 4 and has the usual workup with a CT-head that does not demonstrate any injury. He remains in coma for several days and undergoes an MRI which clearly identifies diffuse axonal injury (DAI) located at the corpus callosum; How would you code this injury and what is your rationale for the choice?

A: Because of the length of coma, the DAI is coded from the concussive section of the head chapter even though we know it is located at the corpus callosum. The coma is consistent for > 24 hours with the MRI appropriately done to confirm the diagnosis and reason for...

Q: A trauma activation is called for a patient with a GSW to the lower abdomen. Immediate laparotomy is undertaken and a perforation to the sigmoid colon identified. The sigmoid is resected, colostomy placed, and the patient moves to the ICU. Please code this abdominal injury

A: The sigmoid is part of the colon and therefore coded to the "colon" in the abdomen chapter. A perforation is identified. The injury should not be coded any more severely just because the sigmoid was resected. Code:540824.3

Q: Patient arrives after a fall down a flight of outdoor stairs. The patient experiences an unknown period of exposure prior to being found and brought to the ED. The initial core temperature on arrival is 90.1 degrees Fahrenheit; What would you do with this information?

A: A tempreature of 90.1F is equivalent to a temperature of 32.3 C and therefore meets criteria for the hypothermia code 010004.2; this is not induced for medical treatment but rather from exposure and is included as an injury.

Q: 36 y.o. female is running across the highway and struck by a vehicle at high speed; she is unresponsive at the scene and has an immediate CT-head which identifies a large bleed likely at the sagittal sinus; Operative craniotomy revealsa laceration to the sagittal sinus with a 2000ml blood loss; the injury is irreparable; How do you code this injury?

A: sadly the blood loss, although massive, cannot be attached to this injury specifically and laceration is the only available code. Code: 122402.4
