Many people still believe that the new ICD-10 CM and PCS code set transition from ICD-9-CM will simply involve one-to-one mapping, but it will also require one-to-many general equivalency mappings (GEMs). This will require analysis, system reconfiguration, and thorough staff training.
One-To-Many Example
With the new ICD-10 coding, sports injuries will be coded with the sport and reason for the injury. Here’s the difference between ICD-9 and ICD-10 coding for sports injuries:
ICD-9 Code
- Striking against or struck accidentally in sports without subsequent fall (E917.0)
ICD-10-CM Detail Codes
- W21.00 Struck by hit or thrown ball, unspecified type
- W21.01 Struck by football
- W21.02 Struck by soccer ball
- W21.03 Struck by baseball
- W21.04 Struck by golf ball
- W21.05 Struck by basketball
- W21.06 Struck by volleyball
- W21.07 Struck by softball
- W21.09 Struck by other hit or thrown ball
- W21.31 Struck by shoe cleats Stepped on by shoe cleats
- W21.32 Struck by skate blades Skated over by skate blades
- W21.39 Struck by other sports foot wear
- W21.4 Striking against diving board
- W21.11 Struck by baseball bat
- W21.12 Struck by tennis racquet
- W21.13 Struck by golf club
- W21.19 Struck by other bat, racquet or club
- W21.210 Struck by ice hockey stick
- W21.211 Struck by field hockey stick
- W21.220 Struck by ice hockey puck
- W21.221 Struck by field hockey puck
- W21.81 Striking against or struck by football helmet
- W21.89 Striking against or struck by other sports equipment
- W21.9 Striking against or struck by unspecified sports equipment
That’s right, there are 24 possible ICD-10-CM detail codes to represent sports injuries, compared to only one ICD-9 sports injury code. This is just one of many examples that busts the myth that this is a simple one-to-one mapping effort.
