Official Coding Guidelines
Complications of surgery and other medical careG. Complications of surgery and other medical care When the admission is for treatment of a complication resulting from surgery or other medical care, the complication code is sequenced as the principal diagnosis. If the complication is classified to the T80-T88 series and the code lacks the necessary specificity in describing the complication, an additional code for the specific complication should be assigned.
Sequence blood vessel/nerve injury first (fragment)injury is to the blood vessels or nerves, that injury should be sequenced first.
