Au contraire, I think it is exactly what we want (if we can dismiss the "sundry detached doctor parts" interpretation).
I don't think {loi mikce} can refer to detached doctor parts. That has to be {loi mikce pagbu}. {loi mikce} can only be some doctors collectively, but only doctors, not doctor parts.
But {mi nitcu loi mikce} says that there is some group of doctors (possibly a singleton) such that I need that group. That's not the usual meaning of "I need a doctor".
