Official Coding Guidelines

Coding injuries: separate codes unless combination; T07; S00-T14.9 notes

b. Coding of Injuries When coding injuries, assign separate codes for each injury unless a combination code is provided, in which case the combination code is assigned. Codes from category T07, Unspecified multiple injuries should not be assigned in the inpatient setting unless information for a more specific code is not available. Traumatic injury codes (S00- T14.9) are not to be used for normal, healing surgical wounds or to identify complications of surgical wounds. The code for the most serious injury, as determined by the provider and the focus of treatment, is sequenced first.

Sequence blood vessel/nerve injury first (fragment)

injury is to the blood vessels or nerves, that injury should be sequenced first.
