The Matrix is a tool for classifying
injury ICD-9-CM codes by body
region and nature of injury.
It is useful for standardized
retrieval of injury cases for
epidemiological, clinical and
management oriented analyses
What is the Matrix?

To characterize the patterns of injury
Matrix objectives
To serve as a standard for casemix comparison
To simplify the process of classifying
injuries To provide a standard format for
reports

Motivation for building the matrix
Sorted by nature of injury
Detecting injuries by body
region
requires collating codes across
chapters

Dissemination
The Matrix was posted on the net by
Lois in October 2001.
A paper describing matrix construction
will be published in the June 2002 issue
of Injury Prevention.

“Five digit ICD-9-CM codes will be used where necessary”.
“Priority codes will not be used, an “other and unspecified” by body region row will be added in order to minimize loss of information”.
April 3, 2001: ICE meeting, Washington DC
General Agreements Reached
“Instructions on how to collapse rows will be available to ensure a standard collapsed table”.

injuries with a specific mention of intracranial injury or loss of consciousness of more than one hour
Original Two-row TBI definition(created by Vita Barell)
A derivation from CDC definitions: concussions with no or short loss of consciousness were classified as ‘possible TBI’.

An addition to the definition: injuries indicating damage to the optic nerve pathways:
•optic chiasm (950.1) •optic pathway (950.2) and •visual cortex (950.3)

•Multiple injury requires timely care by a
number of specialists simultaneously.
•Multiple injury is often associated with
greater severity and mortality.
• ISS takes into account the contribution
of multiple injuries to severity, but does
not profile the injury.
