What I was taught was that if you PLAN to do a reduced procedure (e.g. you know the patient has a portion of colon missing, so you will not be performing a full colonoscopy), then you use a -52 modifier.
If you have to interrupt your procedure, you use a -53 modifier. It describes a "discontinued" procedure when it must be discontinued "due to extenuating circumstances or those that threaten the well being of the patient." That "or" is an important clarifier.
Hope that helps.
