A: The correct code in AIS 98 is 140606.3. Thanks to everyone who participated and congratulations to our three contributors who gave the correct answer. The answer 140604.3 identifies a single contusion, but does not get as specific (“small”) as the correct code. You will notice however that the severity is not affected in this case. In AIS 2005 we have added a new code for these very small lesions in the brain. It is 140605.2 tiny:< 1 cm in diamter and it more correctly reflects the lesser severity of these lesions.
