The abbreviation for 'Complaint of' is what?

• A. c/w
• B. c/o
• C. cc
• D. DNI

Answer: (B)

In medical shorthand, to capture what the patient reports feeling or experiencing, we use c/o, which stands for “complains of.” It signals subjective symptoms described by the patient. For example, saying “c/o chest pain” means the patient reports chest pain. This is distinct from chief complaint, which is the main reason for the visit and is often abbreviated as CC, a label for the visit focus rather than the patient’s own report. The other options don’t fit because c/w is used for something like “consistent with” (or “with” in some contexts), cc can mean chief complaint or cubic centimeters, and DNI means “do not intubate.” So the correct abbreviation for “Complaint of” is c/o.
