A: Hyperdensities generally refer to blood and in these areas are usually either SDH or SAH. The falx separates the right side of the cerebrum from the left side and the tentorium separates the cerebrum from the cerebellum. When blood is described as being “along the tentorium” we code it to the cerebrum unless they

A: 411000.2 breast avulsion female, 410102.2 pectoral muscle laceration, 422008.3 transected mammary artery with > 20% blood loss
A: The vertebral artery is frequently injured at the level of the cervical spine fracture; the srtery traverses the transverse foramina and is vulnerable at this point, thus the CTA examination. Code: 321018.3
A: 240212.1; the ossicles are seen on CT scan but they are the skeletal component of of the ear. Thus, the AIS code for the ossicles is found in the face, under the organ “ear”. This injury is frequently associated with a basilar skull fracture, which would be coded separately. The patient is likely also
;
A: The bilateral code in the AIS dictionary refers specifically to the common iliac artery. In this case the two internal iliac artery injuries would be coded separately, using 520604.3 for the left and the right internal iliac arteries.
A: The correct code is 816014.1 and the injury is assigned to the External ISS body region. Although the dictionary does inclue specific codes for muscle injuries in the Extremities chapters, those codes are intended for blunt injury. Penetrating injuries to the extremity that do not include injuries to specific underlying structures such as vessels
;
A: In AIS 98 the correct code is 851612.2In AIS 205 the correct code is 854465.2Note that the early editions of AIS 2005 did not include this code. Over the last several months, there have been several additions and corrections. Please refer to www.aaam1.org/ais and click on Updated Pages to download the latest updates to

A: These injuries present something of a dilemma. The rules and guidelines that apply include: Code bilateral mandible fractures as a single injury. Displacement must be significant (guideline added to AIS 2005 dictionary). With open fractures, do not code the overlying skin injury. The best choice is to use 250610.2. Open/displaced/comminuted but NFS as to
;
A: There are two correct answers for this question in AIS 98. The code 912020.4 indicates burns to a child less than 5 years of age. The code 912022.4 indicates facial involvement. It is up to the coder to decide which of the two is more important to note their choice of code. Note that
