About the S40–S49 Code Range
These injuries affect the shoulder or upper arm. They include surface injuries, open wounds, broken bones, joint injuries, damage to nerves and other tissues, crushing injuries, and injury-related amputations.
The categories separate injuries by type. S40 covers surface injuries, while S41 covers open wounds. S42 separates fractures by bone or part of the bone. S43 separates dislocations from sprains and identifies the affected joint.
S44 identifies injured nerves, S45 identifies blood vessels, and S46 identifies muscles and tendons. S47 separates crushing injuries by side. S48 separates injury-related amputations by level. S49 includes other and unspecified injuries and fractures at either end of the upper arm bone.
Listed seventh characters distinguish initial encounters, subsequent encounters, and later effects. Fracture endings can also distinguish open from closed fractures and describe healing during subsequent encounters.
