Regarding the original topic, this is what the CPT book says:
"Self-limited or minor: A problem that runs a definite and prescribed course, is transient in nature, and is not likely to permanently alter health status OR has a good prognosis with management/compliance."
Since that is as clear as mud and can easily apply to more serious problems that many would have no problem labeling as "new problems," I usually add what has been posted already in my instruction, that "self-limited" refers to a problem that will usually self-resolve in a few days and really doesn't need medical intervention at all.
Also, here is what one Medicare contractor said:
"Follow-up Questions from the 8/23/06 E&M MDM/PROBE FINDINGS 99214 & 99215 TELECONFERECE with WPS Medicare.
Q) Some of my staff attended a seminar earlier this year and asked for a definition of self-limiting or minor problem vs. a new problem. They stated that someone from WPS said if it required a prescription it's considered a new problem. Is that true?
ANSWER: If a prescription is needed to manage a problem, it is usually not self limited. However, there are some self-limiting problems that will resolve themselves, but a drug is prescribed to help treat symptoms. In the end, the nature of the presenting problem and the diagnosis will determine whether the problem is minor or self limiting."
