T81.31 is a non-billable header ICD-10-CM code for disruption of external operation (surgical) wound, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

The appropriate 7th character is to be added to each code from category T81
