Yes the letter "J" is a roman numeral, but it as not a typical roman numeral. The letters "J" and "I" are interchangeable when the letter "I" is the last letter in the Number Form ( i.e. "MMXVIIJ" instead of "MMXVIII" ). This is an easy way to show the end of a roman numeral, but only if it would normally be ended with an "I". There are different reasons why you would want to indicate the end of the number form, but the main reason is to stop alterations of the number ("VI" cannot be changed to "VII" if the letter "J" is used, "VJ" is a correct number but "VJI" is not). This is why doctors will use the letter "J" when writing a script, to stop someone from changing the number on the script.
