According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.
The appropriate 7th character is to be added to each code from block Superficial injury of head (S00). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Information for Patients
Also called: Contusion, Ecchymoses
A bruise is a mark on your skin caused by blood trapped under the surface. It happens when an injury crushes small blood vessels but does not break the skin. Those vessels break open and leak blood under the skin.
Bruises are often painful and swollen. You can get skin, muscle and bone bruises. Bone bruises are the most serious.
It can take months for a bruise to fade, but most last about two weeks. They start off a reddish color, and then turn bluish-purple and greenish-yellow before returning to normal. To reduce bruising, ice the injured area and elevate it above your heart. See your health care provider if you seem to bruise for no reason, or if the bruise appears to be infected.
