Spider, they are different.

Med. transcription is typing into a computer (like into WORD) notes from a doctor that he or she dictated into a dictating machine like Dictaphone.

Medical coding is assigning a code from a book for each type of medical procedure that has been performed. The code is entered onto insurance forms. There is a large book that has thousands of codes - each one corresponds to the type of procedure. The medical professional (doctor usually) writes down the procedure and the coder looks up the code and enters it on the insurance form.

Hope that helps!
