the difference between sequela visit & follow up

when do we use S & when do we use D for injury?

re: the difference between sequela visit & follow up

Use sequala as a late affect. Say you broke your hip and then developed arthritis in it. That would be a late affect.

Use D for example therapy for the left hip break.

D is for 2nd or more visits of an existing problem. S is the late effects of an injury, burn, piosoning etc.
